Hajime Nagumo/Chronology

History
Hajime's father is a game creator and his mother is a shoujo mangaka. While in high school, his career goals were to eventually get a part-time job at his father’s company or mother’s workplace. This was because he thought his otaku hobbies would help him excel in these fields.

In Middle School, Hajime witnessed a scared grandmother and child apologizing to a punk for accidentally spilling his drink on his clothes. An ordinary passerby would not have gotten involved, but he moved his body unconsciously when he saw the punk start to lay his hands on the child. Knowing that he was no match for the bully but still wanting to protect the child, he knelt down to beg forgiveness for the child even at the sacrifice of his own dignity. Kaori witnessed his bravery and the strength of his heart that allowed him to stand against evil while a weak person and began approaching him at his school every day only in vain until she found him in high school.

Tortus Arc
At the beginning of the story, Hajime was a complete otaku who was always late and always came to class with a sleepy expression. He was frequently bullied and was glared at by both of his male and female classmates for being close to their idol-like classmate, Kaori.

After wishing for his annoying classmates to be summoned to another world, they appeared on top of a pillar-like structure in another world. Then they become saviors called by the god of Tortus, Ehit, thus becoming one of the heroes.

However, he was given the job "Synergist" which was not a cheat-like job with all his stats starting with 10. All of his classmates had cheat-like jobs and stats reaching the hundreds just by being level one. Because of this, he was also bullied for being weak. One night before they are going to the Labyrinth, Kaori decided to visited his room and telling him not to go to Great Orcus Dungeon, because she had a dream that someone is gonna take him away from her. Hajime comforted her by saying that he knew she would be able to protect him.

After that day, they went to Great Orcus Dungeon to level up. They were fine until they reached the 20th floor when Hiyama touched a huge shiny ore in an attempt to obtain it for Kaori to impress her. It was a trap and everybody present was teleported to the 65th floor in the dungeon. There, they saw a lizard-like monster called a Behemoth, that the legendary adventurer was unable to defeat. Hajime helped the scared Yuka who was surrounded by monsters and told her to keep calm or else she would perish. Then, he got mad at Kouki who refused to abandon Meld, saying that someone should lead the panicking classmates. Hajime told Meld to help his classmates after they immobilized the Behemoth. After that, their party was casting magic to kill the Behemoth, but one classmate betrayed Hajime and hit him with a fireball, sending him off a cliff much of the shock of Kaori and the others.

Later in the Abyss, Hajime wakes up to see a giant bear monster and tries to run away, but his left arm is bitten off by the bear and escapes just barely by transmuting a wall to cover himself. After falling into despair, he thinks back to how he got here and becomes determined to return home and will kill anything and anyone who gets in his way. He stops the bleeding in his severed left arm and confronts a wolf monster as he stabs it to death. He then restores his vitality and mana by eating the wolf monster. After Hajime finishes eating, he writhes in agony until he realizes that the wolf meat he eats gave him a new power while he transforms and because of this his hair turned out white. He only survives because of his luck to find a Divinity Stone with limitless Ambrosia in it. After gaining some lightning abilities from another monster, he transmutes a revolver and calls it Donner. He then travels in the abyss killing and eating monsters until he confronts the same bear that ate his left arm. After getting injured again by it, he uses a green glowstone as a flashbang and shoots the monster's left arm off, completely disintegrating it. He then finishes it off by shooting it in the head and then consumes it.

Three days after killing the bear, Hajime continues traveling in the abyss gaining raw material until he confronted 2 cyclopses but kills them instantly. He then comes across a room with a little girl sealed inside some kind of magic box. At first he was leaving her with the belief that she was dangerous, but after she tells him that she was also betrayed, Hajime decided to listen to her story. She says that she's a vampire and was the strongest of her clan until her people betrayed her, so she begs Hajime to help her escape. Hajime then breaks the sealed box with full power transmute. After she was freed, Hajime asks for her name, but she says that she doesn't have one and requests Hajime to give her a new name. He names her Yue. As they are about to leave the room, a monster pops up in an attempt to kill them. They have a hard time killing it, so Yue tells Hajime to trust her as she bites his neck, drinks his blood, and uses one of her strongest attacks called Azure Blaze. Hajime finishes it off by shooting a hole in it and sticking what looks like a grenade inside of it causing the monster to explode. After a month of exploring, Hajime and Yue open up to each other on how they both fell down the labyrinth into the abyss, and Yue decides to tag along with Hajime on his journey back home.

They fight off monsters in a forest until Yue is held captive by a plant monster. Yue tells Hajime to kill it and don't worry about her, and Hajime shoots blowing the plant monster's head off. When it seemed like they made to the end of the abyss, they are immediately cut off by a six headed hydra-like monster. As they fight it off, one of the monsters cast some kind of mind spell on Yue causing her to freak out until Hajime breaks her out of her hallucination by kissing her injecting a potion inside of her. After saving Yue, Hajime tells her to distract the Hydra so that he powers up his secret weapon which is an anti-matter rifle he calls Schlagen. As Yue attacks with another one of her abilities called Crimson Javelin, Hajime then fires a shot with Schlagen at the Hydra blowing off multiple heads at once. When it seemed like they were finished, the 7th silver hydra head shows up and blasts an attack at Hajime mortally wounding him and blinding his right eye. He falls unconscious while Yue desperately fights off the silver hydra with his Donner but she gets mortally wounded as well. Hajime regains conscious and steps behind Yue letting her know that they're gonna end this fight. Hajime distracts the silver hydra while Yue charges up her Azure Blaze. The silver hydra constantly blasts attacks at them, but Hajime dodges them all and transmutes the ceiling above the silver Hydra making it fall on it. Yue then fires her Azure Blaze greatly wounding the silver hydra, and Hajime finished it off by shooting it in the head with his Donner.

Two months after clearing the labyrinth and learning creation magic, Hajime makes himself a prosthetic arm and makes Yue a necklace with a gemstone that contains reserved mana inside. Afterward, they finally leave the labyrinth for good. After some walking, they find a hidden door leading to the outside. They make haste through the Reisen Gorge Canyon until they come across a bunny girl being chased by a two-headed dinosaur-like monster. Annoyed by it, Hajime steps in and kills the monster saving the girl. The girl then reveals herself to be a demi-human and that her family, the Haulia, lived the depths of the forest which was demi-human territory. Unfortunately, because of her abilities she and her family were exiled. The reason why was because originally, demi-humans had no talent for magic, but she have, and she had the ability to manipulate it. She has what's called the Inherent Spell Prophecy, the ability to see the future before it happens. She fears that if she's captured, she will be executed. During their time fleeing into the forest, her family was attacked by imperial soldiers and because her family were non-combative, half of her family was captured. Now she begs Hajime and Yue for help, but Hajime immediately refuses. She desperately begs and asks why. Hajime explains by asking what he gets out of helping a demi-human that has no home yet she has the ability to predict the future. She then admits that the future will change with hard work and that some futures won't change if you do nothing, so she's determined to believe that her vision of Hajime and Yue was meant to be and that she won't give up on them. Yue tells Hajime that they should go with her since they have no means of guidance through the forest and that they won't be defeated so easily. Hesitant on the matter, Hajime agrees to take her along. The demi-human then introduces herself as Shea Haulia. She then begs Hajime & Yue to save her family as she has seen the future in which they save her family.

Grand Gruen Volcano
After leaving Kouki's party, Hajime's party with now including Kaori Shirasaki now travel in Gruen Great Desert to conquer a labyrinth, the Grand Gruen Volcano. They were attacked by multiple desert sandworms, while being ambushed by these sandworms Kaori noticed a collapsed person which is not being attacked by the sandworms. They came to him after dispatching the sandworms, Kaori did a quick check on the person they found, she found that he is suffering from "mana overload" that was ravaging his body, Kaori used a high-ranked healing magic spell which eased the man's condition by extracting some of his mana. After the man woke up he thought of Kaori as a goddess and tried to reach her but Hajime caught him only to be trampled by him, Hajime noticed the clothes of the man that is a specially clothed from the Dukedom of Ankaji, fearing that the disease spread there they might change their course.

The young man's name is Viz Fuad Zengain, Son of the Dukedom of Ankaji's Ruler, Randzi Fuad Zengain. Ankaji is the keypoint in transporting products from the north and also is near Erisen where they intend to escort Myu to. Hearing Kaori is a "God's Apostle" and Hajime's Party of Gold ranks he decided to asked them to help the Dukedom of Ankaji. Viz told them that 4 days ago people collapse due to an unknown disease, from 3000 infected it turns to 20,000 infected after one day. They examined the water of the oasis which sustained them and it turns out that it was polluted, then their water supply storage ran out after 2 days, now they are forced to drink the polluted water which made the 270,000 of their population to be infected of the disease. Viz was ordered to go to the kingdom, if Viz go to the kingdom his words will weight heavy, but upon his travel to the kingdom they were attacked by the sandworms, only he survived. Only with the help of the sillstone can cure the mana overload, but the problem is that the stone is located in the Grand Gruen Volcano. Hajime accepted the request since they were planning to go to the Grand Gruen Volcano labyrinth anyway, and also to secure a place for supplies in Ankaji. They directly head to the palace with Viz. The King of the Ankaji is shocked to see Viz which he sent to the kingdom come back earlier than expected, The royal family is healty due to the serene stones they have, Kaori and Shea go to medical station while Hajime, Yue, Tio, and Myu go to the oasis to examine the polluted water. Yue activated her gravity magic which create a fissure and then a water element magic which fill up the fissure with water, with this the population of Ankaji have clean water supply for the time being. Then he inquire the king on how much have they examined the oasis. Hajime then sensed something in the water and pulled out something in his treasure trove, then suddenly explosions rang and water spouted from the oasis, what Hajime pulled out is a torpedo which he had prepared for the Sunken Ruins of Melusine Labyrinth beforehand, but moments later huge tentacles come out of the oasis.

Viz was shocked by the beast that lurks under the oasis and thought it was a Vachram (a Slime type demon) Yue and Tio hold of the demon with Ice and Fire magic. Viz asked if Hajime can defeat the demon, and Hajime reassured him and pulled out donner and fired at the demon with railgun like power. The attack hit the magic stone which defeated the demon. Randzi asked if the oasis is safe now, Hajime replied that since the source of the pollution is gone the water should slowly return to normal now. As Randzi wondered why Hajime deduced that the demon race is responsible, since Ankaji is in the middle of the dessert that it is no wonder that it is an ideal place to be attacked which will destroy the supply route and the export of local fruits from Ankaji. Randzi thanked Hajime's party for the help, and formally asked them to procure serene stone which Hajime accepted since their target is the Labyrinth of the Grand Gruen Volcano in which it aligned with the request. After dealing with the polluted oasis, Hajime go to the Medical center where Kaori and Shea are and telling Kaori that they will go to the challenge the Labyrinth now. Kaori decided to stay at Ankaji to help tread the diseased persons, Hajime told Myu to stay with Kaori at Ankaji while they challenge the labyrinth.

The Grand Gruen Volcano Labyrinth, unlike other volcano this one is looks like a giant hill wrapped by vicious sandstorm. The party is glad that they have the 4-wheeled vehicle in this situation and Hajime just go for it. Demons like sandworm spotted attacked them but they were countered by Yue with wind element magic. After a few battles on their way they finally got out of the sandstorm, and since the angle gets steeper that got out of the vehicle and climb up the volcano. Inside the labyrinth they found serene stones in small quantity which Hajime stored for the request of Randzi. They encounter various monsters such as Magma bull, and Bats. Worst of all is under those circumstances the scourging heat emitted at the labyrinth is getting to them. Afterwards they continued to collect more serene stones as they progress but due to Hajime's carelessness the effect of the serene stone is lost and causing the lava to become unstable. Hajime created a small boat able to withstand the lava and they go along the flow of lava going deeper under the labyrinth. Bat-type monsters show up and attack them but they were neutralized.

Then they reach what seems the end of the labyrinth, a small island can be seen at the center of the place. Hajime's party headed for the island, he examined the island then serpent type monsters show. Shea noticed something shining at the wall and notified Hajime about it. Hajime deduced that they needed to finish of the monsters in the area to clear the labyrinth. The conditions seems a lot more difficult, lava come out bursting without any notice, the intensive heat that the labyrinth produce, lava all around with just a few place to step on, and the monsters that attack them. As the battle continues they are nearing the end of exterminating the monsters but at the very last one a sudden beam defeated the monster and damaging Hajime as well.
