Kouki Amanogawa

Kouki Amanogawa is a major character from the "Arifureta Shokugyō de Sekai Saikyō" 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.

in the After Story, Kouki was summoned by the Queen of the Synclea Kingdom, Moana de Shelt Synclea to fight against the "Dark Beings". Following defeating the Dark "Beings", He was summoned again to another world. He and his new two companions (harem) travel to Tortus, adventuring and exterminating monsters.

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 180cm.

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 a kind, fair, and overflowing with sense of justice. However since he never thinks he's wrong, he has a bad habit of interpreting adverse situations to his own convenience. 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. As he grows, he is 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 ignore it and simply believe in his righteousness, making him extremely arrogant, foolish and delusional about himself. This only worsen 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. Hajime noted the reason why he didn't bother telling him and the rest of their classmates about Ehit's true nature was because Kouki wouldn't want to believe that Ehit who had chosen him to be the Hero is evil and that his heroism efforts was completely pointless and would just get mad at him instead, something Kouki couldn't deny. As Hajime pointed out, Kouki is naive enough to believed that his classmates are always obligated to help and protect each other, as after Hajime rescued them from Cattelya's ambush, Kouki mistook Hajime's cold refusal to rejoin them in cooperating in the war against Demons despite having extremely powerful firearms and Artifacts as an sign of utter selfishness, in reality Hajime refused to rejoin them due to having learnt of Ehit's true nature and his schemes in using them as pawns in a twisted game of death which Kouki would refused to believe even if Hajime did warned Kouki about it. Kouki even stated that Hajime could have convinced him of Ehit's true nature by thoroughly explaining it several times, Hajime simply mocked Kouki, stating that his convenient delusion of the fact that classmates must be obligated to help each other is what had allowed the intelligent, Eri and the treacherous idiot, Hiyama to betrayed him without even realizing it.

Because of his self righteousness and egotism, Kouki can't accept things when it doesn't go the way he wants, making him act like a spoiled child, a very rude man and a persistent idiot. This was seen when Kaori decide to follow Hajime on 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 that took her away. He further mistake that all the girls who were following Hajime were being force 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 but only ended up to Kouki's easy and humilating defeat by Hajime as he tossed Kouki to a pitfall filled with non-lethal bombs.

Unlike most of his classmates who taken Hajime's warning seriously, Kouki doesn't take Hajime's warning seriously as he is extremely persistent in believing that he is still stronger than Hajime due to being blessed as Ehit's chosen hero as well as his own delusional pride in his misguided and childish righteousness. However, his attempts has only makes it worse for him when he was unable to clear a single labyrinth and Hajime easily cleared almost all of them as Kouki ended up losing to Hajime twice the first when he challenged Hajime for Kaori and his harem and the second time when he attempted to kill Hajime to fufilled his misguided justice due to Kouki's emotional weaknesses and lacks of resolves. Kouki became gutless of Hajime's true power as he witnessed Hajime's brutality when he murdered Hiyama. Unlike his classmates who were praised by Hajime and his harem, Kouki didn't receive any praise from them at all when he continually enforcing his delusional and idiotic ideals.

Due to his always being successful in everything he did when he was on Earth and being summoned to Tortus as a Hero, Kouki has developed immense 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. 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. He gets irritated and annoyed when he learns that Hajime had ended up saving more people for the sake of his lovers despite Hajime's personal disregard for heroism and morality by murdering people who go against him and Kouki's own desire to save everyone. Despite Kouki insisting that Hajime take them along with him in order to gain Ancient Magic to defeat Ehit, Kouki doesn't wish to accept what he believes as charity from Hajime as he strives to prove his righteousness by proving he is stronger than 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 than Hajime got worse after Kouki failed to clear the Haltina Labyrinth as that failure made him more irritated and increased his animosity towards Hajime. According to Hajime, it was ultimately Kouki's choice to always priotize his justice and ideals over the importance of realizing his goals that led to all of his own failures in the first place. Kouki did not have the conviction to be pragmatic by temporarily put aside his idealistic righteousness when necessary, even in life or death situations that demands it as Hajime had to when he was forced to abandoned his kindness and morality in order to survive the Orcus Dungeon, as shown when Kouki stated his beliefs that great power must always be used for justice at all times regardless of a person's circumstances such as when he learned about Ehit's true nature as an Evil God and quickly presumed that Hajime is gathering Age of God's Magic for the sake of defeating Ehit and was frustrated when Hajime refused to give a damn about Ehit's malice towards Tortus. When Hajime had to searched for the captured Haulia Tribe in Hoelscher Empire, Kouki was angry at Hajime for seemingly ignoring the plight of the enslaved Beastmen and nearly caused a commotion which Hajime had to threateningly remind Kouki his original purpose in accompanying his party for Age of God's Magic. Even, when Hajime helped the Haulia Tribe to liberate the enslaved Beastmen, he was aghast by the methods they used to do so by assasinating the nobles and using threats to forced Gahard to agree in liberating the enslaved beastmen.

Kouki is easily swayed by his emotions, making him increasingly reckless as he tends to act without thinking about the present situation as well as his weaknesses has made a fool of himself. Even through this has been pointed out by Shizuku several times and has even almost got him kill, 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. During his second battle against Cattleya, Kouki stopped his blade when he was about to kill the demon due to the realization that he was able to kill a sentient being, something Cattleya berated him for doing, who 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". 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 there 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 had feelings for Hajime back on Earth, and instead believed she only talked to Hajime because she felt bad for him. In truth, He is actually a deluded pervert who is obsessive of both Kaori and Shizuku and wanted them to be with him but failed they are not interested in romance with him as they already have romance feelings for Hajime. He is more idiotic pervert who thinks Hajime mistreated his harems and offer them to join him to treat them "better" which greatly annoyed them. 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. However, with Hajime's newly appearance, Kouki is extremely jealous to Hajime for his harem ability of getting attractions from beautiful girls that includes Kaori (who holds a greatest love for Hajime during middle school) and Shizuku (who also loves Hajime). While his failed attempted to kill Hajime only to be easily defeated, Kouki became upset after he got slapped in the face by Kaori and told by Shizuku that she is in love with Hajime as well to stop bragging at them as she want to be together with Hajime due to him hurting their feelings.

While traveling through the Frost Cravens of Schnee, Kouki showed signs of growing increasingly unstable. Despite repeating 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 continue to deny everything his copy said, which only made his copy stronger as he wasn't accepting his negative qualities. Once he saw Shizuku sleeping peacefully on Hajime back, he completely snap, choosing to believe Hajime was brainwashing everyone and everything would be return to being "right" if he killed him. His logic likewise grew increasing 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 for many 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 misguided righteousness after his defeat by his former classmate, Hajime.

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 guilt due to not trusting his own judgement of killing Hajime which almost broke his relationship with Kaori and Shizuku. This is reflected on the fact that he is initially more reluctant to be enlisted to help others. After meeting Moana and the people of the 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 the Synclea Kingdom, so Kouki could save the woman he fell for and finally found a newly romance after got kissed at cheek by Moana. 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.

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?"
 * (Kouki 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 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 been mine! 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, how come everyone likes YOU!? It doesn’t make sense!"
 * (Corrupted Kouki to Hajime Nagumo): "Please, Nagumo. Give it all back to me. I’m begging you, please just die."
