Kouki Amanogawa

Kouki Amanogawa is a major character from the "Arifureta: From Commonplace to World's Strongest" series.

He is one of the students from Japan who got involved in the summoning incident, and ended up in Tortus along with his other classmates. He is somewhat like the leader of the whole class, as most of the students look up to him. This is further enforced by him being blessed with the rare job as the Hero.

Appearance
Kouki is a typical  (good-looking man), with good looks, athletics, smarts, and a good personality. He has silky brown hair and gentle eyes. His body is toned and slender at about 180 centimeters.

Personality
"I’m going to fight. If we save everyone, then we can go home. So just you watch! I’m going to save everyone, including us!"

- Kouki proclaiming his desire to save Tortus Kouki is kind, fair, and overflowing with sense of justice. All these factors mixed with his beautiful appearance, makes the vast majority of people consider him a perfect man, but in reality, Kouki is an extremely flawed man, and although he is not an intentionally bad person, by no means can he be considered a decent person. Kouki is actually an extremely arrogant, ignorant, hypocritical, childish, spoiled, incompetent, irresponsible, reckless and with an extremely weak and delusional determination. He believes he is never wrong, so he misinterprets any situation to suit his own point of view, ignoring reality, as he only wants to hear and see what he wants.

This stems from his childhood. During his childhood he greatly admired his grandfather that would teach him his ideals of righteousness and justice. After his grandfathers death, Kouki held to his grandfathers teaching of ideal righteousness. Even so, the righteousness that his grandfather taught didn’t recognize good and evil at all. To further say it, Kouki came to think that what the majority of people thought as right was the absolute right, which is completely useless, because reality is much crueler and darker than you ever thought it was. As he grew, he was capable of overcoming many problems while holding to his ideal. As a result, without realizing it, Kouki came to not doubt his own righteousness. Despite being cautioned by several people close to him, especially by his parents and Shizuku, he ignores them and simply believes in his righteousness, making him quite arrogant, dimwitted, foolish and delusional about himself. This only worsens after being summoned to Tortus, where the Holy Church and the Kingdom of Heiligh labeled Kouki (and his classmates) as their Hero who was sent by their God to save them from the demons, something he took absolute pride in believing. Summoning as a "Hero" to Tortus only fueled his empty ego and his delusional, pathetic sense of "justice".

Because of his self-righteousness and egotism, Kouki can't accept it when things don't go the way he wants, making him act like a spoiled child. This was seen when Kaori decide to follow Hajime of her own free will. He couldn't accept it as he always believed that they should be together forever and would rather believe that Hajime is the one who took her away. He further mistakes that all the girls who were following Hajime were being forced by him and tried to get them to come with him instead by saying he will treat them better than Hajime, which only greatly disturbed them because of how far off the mark he was. This only upset him further, causing Kouki to challenge Hajime to a duel for them, which was no different from him trying to take them by force. Hajime noted the reason why he didn't bother telling him and the rest of their classmates about Ehit's true nature as an evil god was because Kouki wouldn't want to believe that he was never a chosen hero and all his heroism efforts were completely pointless and would just get mad at him instead, something Kouki couldn't deny.

Due to always being successful in everything he did back on Earth and being summoned to Tortus as a Hero, Kouki has developed immense narcissistic pride in himself and his abilities as he believes that due to him being the Hero, others should follow his lead and that he is the person who will save everyone. This is displayed when Hajime killed the demon Cattleya over Kouki's protests despite her previous attempt to kill the Hero Party and the Kingdom knights, as to him, killing a person was wrong and thus condemned Hajime for not following his commands. His arrogance even deluded him into believing that he is stronger than Hajime due to being blessed as Ehit's chosen Hero, even self-righteously challenged Hajime to claim his harem for himself. However, when Kouki nearly died in Eri's death trap during Fried's invasion and also witnessed Hajime's real power as he not only destroyed a zombified Meld and the other Heligh Kingdom Knights, even effortlessly killed Hiyama, one of the strongest of his fellow Heroes with his bare hands, Kouki's pride in himself was badly damaged, which worsened when Aiko exposed Ehit's true nature as an Evil God and his schemes in using him and his classmates as pawns in a mad game of death in which all the hero worship Kouki had received from the Holy Church was nothing more than a fabricated lie.

Unable to accept his own failures and the truth about Ehit, Kouki even attempted to vent his frustration on Hajime, by blaming him for Ehit's schemes in helping Eri and Hiyama's betrayal that led to the Heligh Kingdom's invasion by Fried. Even when Hajime point out it was Kouki's own personality flaws and naivety that lead to Eri and Hiyama's betrayal. Kouki still refused to acknowledge it, preferring to blame Hajime for the problems that he himself had caused it due to his pride and arrogance in himself. Kouki was the only one who condemned Hajime for murdering Hiyama despite the latter being a despicable traitor who killed Meld and the Heligh Kingdom Knights and also temporarily murdered Kaori Shirasaki and attempted to make her his undead sex slave. Kouki seeks to enforce his morals and ideals onto others as he believes that he knows what is best as he often clashes with Hajime over what actions to take as Hajime outright refused to follow Kouki's ideals due to his pragmatic and realistic mindset. He gets irritated and annoyed when he learns that Hajime saved more people despite Hajime's ignoring the plight of Tortus and Kouki's own desire to save everyone. Despite Kouki insisting that Hajime take them along with him, Kouki doesn't wish to accept what he believes as charity from Hajime as he strives to prove that he is right and stronger then Hajime. This is shown in the fact that Kouki is reluctant to use the upgrades to the Holy Sword that Hajime added. This desire to prove himself stronger to Hajime got worse after Kouki failed to clear the Haltina Labyrinth, as that failure made him more irritated and increased his animosity towards Hajime.

Kouki is easily swayed by his emotions, making him increasingly reckless as he tends to act without thinking about the present situation. Even through this has been pointed out by Shizuku several times and has even almost got him killed, he rarely reflects on this issue. This has proven to be his greatest weakness, as he will hesitate when he learns new information about his enemy and always ending up giving them an opening to defeat him. This is seen during his second battle against Cattleya, where he stopped his blade right after he succeeded in getting in close enough to finish her off due to seeing her giving her final prayer to her loved one as she prepared to die due to realizing that he was about to kill another sentient person and not a mindless "monster" as he initially though the Demon Race was. Eri also made uses of this weakness by making the undead Meld appear as if he could be saved, causing Kouki to stop his blade once again before he could finish his opponent, getting defeated as a result.

He has a large amount of charisma, but always charges straight forward without thinking of the consequences. He also has a naive, childish outlook on the topic of love and the topic of killing. Kouki is often too optimistic for his own good, usually failing to consider the possible dangers surrounding him at times. Even when the situation in the palace was becoming suspicious, he still failed to consider the possibility that he and his classmates were being surrounded by the enemy. This ends up also affecting most of his classmates as they all look up to him; so when he says there's nothing wrong, they believe it without considering whether it's true or not.

Another noticeable trait about Kouki is his denseness. Despite being very popular with many different girls on both Earth and Tortus, he failed to notice this. Similar, he completely failed to notice that his childhood friend Kaori already had feelings for Hajime back on Earth, and instead believed she only talked to Hajime out of sympathy. Even when she confessed to Hajime right in front of him, he still couldn't believe it. It's because of his denseness that neither Shizuku or Kaori ever found themselves attracted to him, despite knowing him for so long.

Another aspect to Kouki is his apparent innocence. After he and his class were summoned to Tortus and the situation of the Human-Demon War was explained to them and their role as "Heroes" summoned from another world to help humanity defeat the Demons, Kouki was completely oblivious to the true implications of their situation and instead got swallowed up by the glamour presented by the Kingdom and the Church of being the Chosen Heroes. This is seen where unlike Shizuku and Hajime, Kouki failed to recognize the fact that they were now going to tangled up in an actual war against two races and thus were now doomed to face the inevitable prospect of having to kill sentient life in mass. A clear example of his innocence is seen during his second fight against Cattleya, where Kouki stopped his blade when he was about to kill the demon due to the realization that he was about to kill another sentient being, something Cattleya berated him for as they were two enemy combatants in opposing sides, as she also later revealed that Kouki most likely only ever considered and saw those of the demon race as "animals" or "monsters" and viewed the war against the Demon race as simply "hunting" and was completely oblivious to the implications of a genuine war

As revealed by Hajime and acknowledged by his close friend Shizuku, despite these numerous negative traits, Kouki himself is completely and utterly oblivious to them and due to things having always work out for him in the end back on Earth in whatever he did, Kouki himself developed the unconscious habit of automatically misdirecting and misidentifying his feelings in order to validate and mask his negative feelings and insecurities through his empty ideals of justice in order to cope with them in order to "be in the right" instead of properly acknowledging them.

While traveling through the Frost Cravens of Schnee, Kouki showed signs of growing increasingly unstable. Despite repeatedly saying he would save and protect everybody, he continually failed at every turn, including failing to clear the Haltina Labyrinth. Worse for him, Kouki's own teammates were doing a better job than him and were getting praised from Hajime and his party for it. While facing his copy during the final part of the trail, Kouki continued to deny everything his copy said, which only made it stronger as he wasn't accepting his own flaws. Once he saw Shizuku sleeping peacefully on Hajime back, he completely snapped, choosing to believe Hajime was brainwashing everyone and everything would be return to being "right" if he killed him. His logic likewise grew increasingly erratic/crazed and delusional to the point that almost every assumption made by Kouki bared little to no relation or connection to the very situation, leading his closest friends to wonder how he had even come up with these conclusions. Despite this however, he still believed in whatever he made up due to refusing to accept his errors. However, he became doubtful after he almost broke his relationships with Kaori and Shizuku due to his stubborn adherence to misguided righteousness after his effortlessly defeat by his former classmate, Hajime.

However, despite this and seeing how much Hajime suffered to get where he is, he still desperately wanted to believe he was right all along. This made it easy for Eri to brainwash him and make him her puppet, all while ironically thinking his friends were the ones being brainwashed. Interestingly, this was exactly what the Haltina Labyrinth and Frost Cravens of Schnee tried to prepare those who planned on challenging the gods for; the gods would turn them against their friends and manipulate their inner weaknesses. This proved once again why Kouki failed to clear both Labyrinths.

In the After Story, due to his past failures and mistakes, he has lost his childishness and naivete along with most of his confidence and has become far more insecure and guilty due to not trusting his own judgement. This is reflected on the fact that he is initially more reluctant to be enlisted to help others. After meeting Moana and the people Synclea Kingdom, Kouki was able to find his answer and not hesitate anymore, killing several thousands "Dark Beings" to save Arquette. Kouki's growth and his desire to save Moana impressed Hajime enough that Hajime lend his power to save Synclea Kingdom, so Kouki could save the woman he fell for. Due to this, Kouki was able to make peace to Hajime as both acknowledged each other by hating the other, in contrast to Hajime's previous dismissal of him and Kouki affirming that despite his dislike of Hajime, he admires his resolve and his ability to push forward no matter what.

Weapons & Equipment

 * Holy Sword Uralt - As a hero, Kouki has the Holy Sword Uralt - a divine Artifact which is a legendary weapon used by various heroes in the past. It is a unique Artifact that possesses various abilities. The sword is blessed by the element of light and has the ability to weaken the enemies struck by its light while increasing the physical strength of the wielder. The sword can summoned to the user's hand and for some unknown reason, it also possess the ability to automatically return to its owner without their consent, when they move away from it for a certain distance or try to abandon it. It can change its shape into whatever type of sword its user wishes, for instance, changing from its western design into a katana. The sword is made of minerals near the root of the Great Tree. It contains the soul of the first avatar of the Great Tree. Due to the unique construction of the sword, the sword cannot be modified to a great extent as making adjustments to the core can potentially weaken the sword instead of strengthening it. Despite the cutting power of the sword, the sword cannot cut through objects made of Azantium. It is the only piece of gear that Kouki retained as he returned all other kits that Heiligh Kingdom issued to him...or to be more accurate, the sword refused to be parted with Kouki. In post-Ehit era Tortus, it'll be Kouki's signature item despite him draped in common adventurer's garb.


 * Divine Armor - The strongest armor Artifact in Heiligh Kingdom. It is a set of nigh-impregnable western-style holy armor that increases the defensive capabilities of the wielder. It is later enhanced by Hajime after acquiring Evolution magic so that it can absorb mana from its surroundings and lessen Kouki's mana consumption, as well as increasing the duration of his "Limit Break". It is also upgraded with the ability to form a veil of light to be used as a barrier. However, his armor was damaged when Hajime bypassed his defense and sending him flying towards a frozen wall. After his second ease defeat by Hajime, the armor was later repaired by Nagumo (despite of his mutual dislikes for Kouki due to his self-righteousness and dimwittedness). It has been returned to Heiligh Kingdom prior his return to Japan.
 * Aerodynamic-Enchanted Boots - They allow Kouki to walk mid-air.
 * Bangle - It grants its wearer the skill "Diamond Skin".
 * Treasure Trove - A ring-shaped Artifact that had small oe centimeter ruby set in its center. The ruby was actually an artificially created dimensional space where things could be stored.

Physical Abilities

 * Enhanced Physical Abilities -Being both one of Ehit's summoned warriors and the Hero on top of it, Kouki gained all around superhuman physical abilities. His stats are among the highest in the Hero party only being surpassed in speed by Shizuku is speed and Ryutaro in strength after he powers up with magic. Despite being the strongest fighter of the Hero party, his abilities has inferiority to Hajime and his companions even with "Limit Break" and fused with his doppelgänger which are still not strong enough to match for Hajime as Kouki's abilities are 12 times weaker than Hajime as he was unable to touch or hit Hajime during his second fight even Ehit now viewed Kouki to be useless for being far too weak. With his failures to acquire "Age of Gods" magic, Kouki is currently stronger than all the classmates but significantly weaker than Hajime and his wives.
 * Enhanced Strength - Kouki possesses enhanced strength which is further enhanced by the power of his Holy Sword. Kouki's strength stats are the highest in the Hero Party, only being surpassed by Ryutarou when he enhances himself with body strengthening magic. When he enhances himself with "Overload", he was able overpower and bisect Cattleya's monster army and penetrate her earth shield with ease. However, in his second fight with Hajime even when merged with his doppelganger and used "Limit Break", his strength and power up were still far too weak to match for Hajime's immense strength
 * Enhanced Speed - Kouki possesses enhanced speed, being the second fastest member of the Hero Party, only being surpassed by Shizuku, who is a speed based fighter. However, his speed is very sluggish as he was unable to catch up to Hajime's immense speed (that is even greater than Shizuku herself)
 * Enhanced Durability - Kouki has enhanced durability giving him the ability to witstand attacks such as Cattleya and her monsters' attacks with moderate injuries. He was able to withstand Ryutaro's gauntlet enhanced attacks and his Metamorphosis transformation as well Shizuku's Black Blade strikes. While he is very durable, his durability cannot withstand Hajime's strength as the latter breaks through Kouki's defensive abilities and severely damaging Kouki by sending him flying to a frozen wall even when using "Limit Break" and fused with his doppelgänger. Both of his kneecaps and shoulders weren't durable after both of them gotten shot by Hajime's guns.
 * Enhanced Endurance - Kouki has an enhanced degree of endurance which he honed by fighting in the Great Orcus Labyrinth and other Labyrinths. After he obtained the skill "Limit Break- War Demon", his endurance was further increased as he was capable of fighting several thousand "Dark Beings" for several days without succumbing to his accumulated injuries. While his second fight with Hajime, Kouki coughed out blood when taking severe damage from Hajime.
 * Enhanced Senses - Due to his "Sense Presence" and "Sense Magic", Kouki has good situational awareness as the Hero Party relied on him to detect oncoming threats. However his sense skills are inferior to Hajime's who has the same skills and several derivative skills with them which he continuously honed and Shea, who's enhanced hearing allowed her to detect threats a moment before Hajime.
 *  Master Swordsman - Kouki has trained in Kendo and the Yaegashi dojo since a young age. After being summoned to Tortus and receiving further training by the likes of Meld Loggins, who was the best swordsman in the Heiligh Kingdom, Kouki skills with a sword have been further honed. By combining his swordsman capabilities with the skills "Serene Mind" and "War Demon", Kouki was able to kill several thousand "Dark Beings". Alberti his limit is 10,000 regardless of which types of enemies come his way and even then he could die way before reaching that number if one of his enemies hit one of his vitals.

Magical Abilities

 * Enhanced Mana - Being the Hero, Kouki has higher mana than most humans. Among the Hero party, Kouki has the highest mana capacity with the exception of Kaori, who trained relentlessly and increased her mana capacity.
 *  Skilled Magic User - Thanks to his job as a Hero, Kouki is fairly skilled in magic, capable of using all elements magics specializing in offensive Light magic that is enhanced by the power of his Holy Sword. While he lacks the same level of mastery as those's who specialize in magic, Kouki has enough skills to uses high level spells in rapid success.

Combat Styles & Techniques

Quotes

 * (To Kaori Shirasaki): "This doesn’t make any sense. You’ve always been with me, Kaori... Why would you want to leave now? You’re my childhood friend... so... you have to stay with me. Isn’t that right?"
 * (Trying to convince Kaori to stay with him and the others): "Kaori. You can’t go with Nagumo. I’m saying this for your own good. Look at him. He has girls all around him, and he’s even got a daughter now... Worst of all, he’s put a slave collar on that rabbit girl. And that black-haired girl called Nagumo her master earlier. He’s probably forcing them to come with him. Nagumo probably thinks girls are nothing more than objects to add to his collection. He’s scum. Look at how easily he kills people. And even though he’s so strong, he’s refusing to help us, his comrades. Going with him will only bring you misfortune. It’s better if you stay with us. No, I’ll make sure you stay with us. Even if you hate me for it, it’s for your own good. I won’t let you go, no matter what!"
 * (Kouki trying to get Yue and the others to leave Hajime): "You girls as well. You shouldn’t stay with him. Come with me! Our party would love to have people as strong as you. We can save the human race together. You said your name was Shea, right? Don’t worry. If you come with me, I’ll free you right away. We don’t keep slaves here. You too, Tio. You won’t have to call Nagumo your master any longer."
 * (To Hajime Nagumo): "Hajime Nagumo! Duel me! No weapons! If I win, you have to promise to never get near Kaori again! And to release those girls you’re holding captive!"
 * (Kouki lamenting his frustrations about Hajime): "Back when we were in Japan, he was a nobody. Just a lazy, unmotivated otaku who wasn’t even good at studying or sports. Always smiling like an idiot. He just did whatever it took to escape the situation he found himself in... He wasn’t even that nice to Kaori... Plus, he was an otaku... I’d never treat Kaori like that. I was always nice to her. I did everything I could for her... so how come Nagumo’s the one with the harem? He doesn’t even respect those girls! Besides, he’s a murderer! He killed that demon, even though she was helpless to resist. There’s something wrong with him! I knew it, it’s just too weird that Kaori likes him."
 * (Kouki to Hajime when learning Ehit's true nature) "What do you mean?! Are you saying we've been pawns in the god's game this whole time?! Why didn't you tell us sooner?"
 * (Kouki demanding that Hajime take his party to the Labyrinths): "There’s no way we can leave Liliana in the care of a guy who says he doesn’t care about this world. We’ll be her guards. Also, if you won’t do anything to save this world Nagumo, I will! But first, I need strength! I need the same ancient magic you have! If I travel with you, I’ll be able to obtain it too, right!?"
 * (Corrupted Kouki to Hajime Nagumo): "Nagumo, even if you’re a former classmate, don’t think you can get away with hurting my friends. I’m gonna kill you and free Kaori and the other girls from your brainwashing! Then I’ll save the world together with them!"
 * (Corrupted Kouki to Hajime Nagumo]]): "You—Guys like you always talk like they know everything! But I’m the one who truly understands Kaori and Shizuku! I’m the one who cares about them the most! I’m the one they should be together with! Not you! Not a shitty scumbag like you!"
 * (Corrupted Kouki to Hajime Nagumo): "It’s all because of you! If you weren’t here, everything would be perfect! Kaori and Shizuku would have always been mine! As the Hero, I would have saved the world! But you ruined everything! Even though you’re a murderer, even though you abandon people without a second thought, such a worst type of person like you, there is no way people would ever like YOU!"
 * (Corrupted Kouki to Hajime Nagumo): "Please, Nagumo. Give it all back to me. I’m begging you, please just die."

Trivia

 * Ehit specifically summoned Kouki and gave him the "Hero" due to how easy it was to manipulate Kouki as a pawn and his potential as an alternate vessel for the god to inhabit. The other members of the class were simply tag-alongs to the evil God's game board.

 * In the Web Novel, Kouki was not transformed into an Apostle-hybrid after falling under Eri's mind-control.
