Hajime Nagumo/Chronology

History
His father was a game creator and his mother was a shoujo mangaka. His original plans while in high school was to eventually get a part time job at his father’s company or mother’s workplace.

And all his Otaku hobbies were perfect for practicing his skills for his future plans and occupation.

In Middle School, Hajime had witnessed a scared mother and child apologizing to a punk for accidentally spilling something on the punk's 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 once witnessed this bravery and the strength of his heart that allowed him to stand against evil while a weak person and began approaching him everyday once she found him in high school.

Tortus Arc
At the beginning of the story, Hajime was a complete otaku in his class who always and always comes to class with a sleepy expression. He was always bullied and was glared 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, the next thing he saw was that they were on top of a pillar-like structure in another world. Then, they become saviors called by the "GOD" on Tortus, Ehit, thus becoming one of the heroes.

However, he had 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. He was thus also bullied for being weak. After that, Kaori visited his room, telling him not to go to Orcus Dungeon, because she had a dream that someone is gonna take him away and Kaori can't just sleep with that thought. But Hajime comforted her that even if he will go with them, he will not be in any danger because Kaori is there to protect him which made Kaori happily nod in agreement.

After that day, they went to 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. It was a trap and everybody present was teleported to a lower floor in the dungeon. There, they saw a lizard-like monster called "Behemoth" which was the monster that was not defeated even with the legendary adventurer who reached the 65th floor. Hajime helped a girl surrounded by monsters and told them to keep calm or they are gonna die. Then, he got mad at Kouki who was full of justice and wouldn't leave behind Meld, saying someone should lead the panicking classmates. Hajime told Meld to help him after his classmates where it is safe while he was preventing the Behemoth from moving. After that, their party was casting magic to kill the Behemoth, but one classmate betrayed Hajime and hit him with a "Fireball" which caused him to fall off the cliff.

He wakes up to see a giant bear monster and tries to run away, but his left arm is bitten off by the demon. Falling into despair, Hajime transmutes a hole to escape pleading for his life. He thinks back to how it all started for him and becomes determined to return home and will kill anything and anyone who gets in his way. He stops the bleeding in his severed arm and confronts a wolf monster as he sadistically stabs it to death. He then restores his vitality and mana and eats the demon to fill up his stomach. After finish eating, he starts feeling agony until he realizes that not only did his hair turned white but he also gained a new power. After gaining some lightning abilities, he transmutes a revolver and calls it Donner. He then traverses the abyss killing and eating monster until he confronts the same monster that ate his 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 traversing the abyss gaining raw material until he confronts 2 cyclopses but kills them instantly. He then comes across a room with a little girl sealed inside some kind of magic box. She then explains that she was betrayed. She then explains 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 obliges and breaks the sealed box. Hajime asks for her name, but she says that she doesn't have one and asks Hajime to name her. He names name 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 and 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 it 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're immediately cut off by a hydra-like monster. As they fight it off, the monster 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 monster 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 at the monster blowing off multiple heads at once. When it seemed like they were finished, the hydra regenerates and blasts an attack at Hajime mortally wounding him and blinding his right eye. He falls unconscious while Yue desperately fights off the hydra with his Donner but 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 hydra in its true form while Yue charges up her Azure Blaze. The hydra constantly blasts attacks at them, but Hajime dodges them all and transmutes the ceiling above the hydra making it fall on it. Yue then fires her Azure Blaze greatly wounding the 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 outside. They make haste through the Raisen Grand 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 Shia did, 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. Shia 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. Shia 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.
