Yukitoshi Shimizu

Yukitoshi Shimizu was one of the students from Japan who got involved in the Summoning Incident, and ended up in Tortus along with his other classmates. He was part of "Aiko-chan's bodyguards", but later betrayed them and joined forces with the demons. He was killed by Hajime Nagumo.

Appearance
Yukitoshi was a young man with a pale complexion, black hair in an unkept fashion, black eyes with black bags underneath them and freckles. Due to his moodiness and negative emotional state, Yukitoshi is shown to have a very crazed/haggard appearance.

Personality
He was an isolated person who didn't have any friends, so he was described as a "mob character". He was always reading books in his seat while never talking to others in anything louder than a mutter. This is in part due to the fact that he was bullied in junior high and did not want to experience that again. Due to his hobbies and anti-social personality, he became a habitual truant and would constantly have dark thoughts floating around in his mind about his family and classmates.

Yukitoshi had always wanted to be special. However, he also wanted to be the only one who was special among his surroundings. When he thought he got his wish after being transported to Tortus, he learned he wasn't the only one who was special and wasn't even the 'hero' he wanted to be, which didn't sit well with him. Even when he thought he could prove that he was better than everyone else, things didn't go the way he wanted and became depressed. These desires grew into insanity when the demons offered to treat him as their "hero" if he killed Aiko.

Despite wanting to be a hero, Yukitoshi wasn't so strong willed and never cared about anyone but himself. When things didn't go the way he hoped they would, he blamed his failures on everyone around him. This made him rather cowardly and shameless, as seen when he was about to die, he begged someone to save him even after everything he tried to do before.

Biography
Yukitoshi Shimizu was a closet otaku who was bullied throughout his junior high school life. With special interest in other-world fantasy adventures he numb his real-world pains with fantasizing himself as a world saving hero character winning ladies left and right. When he entered high school, he hid his interests well to avoid the kind of harsh treatment that would come from it, having seen how his classmate Hajime was constantly bullied for it. His anti-social behavior got to a point where even his family was concerned about him. After being transported to Tortus with the rest of his class, he was excited that his long-time dream finally be realized, only to have his spirit crushed when he found out he was no more than a side character due to the limitations of his Dark Magic. The supposed death of Hajime hit him hard, he withdrew himself and buried himself in books related to Dark Magic. It was then dawned to him that his affinity opens to specialty with dark subjugation magic. At first, he'd sneak outside the palace walls at night to trial out on low-tier monsters, since such magic difficult to affect beings of higher sapience such as humans. He took up the opportunity to travel as one of his teacher Aiko's entourage, in order to further experiment with his dark subjugation magic on higher tier monsters typically found in the mountainous region.

While Yukitoshi and the rest of Aiko's entourage were at the lakeside town of Ur, he was approached alone by a Demon named Reiss and an attachment of Monsters. Reiss made a deal with Yukitoshi, that should he destroy the town and kill Aiko for the demon kingdom. Yukitoshi be invited into Demon's ranks as their hero. Gifted with a small cadre of powerful monsters, he then sneaked out of town and to the Northern Mountain Range to gather more monsters for his army. While there, he encountered the Dragonman Tio Klarus who was sleeping in her dragon form. He managed to control her after a day of using his magic and tasked her to kill all approaching adventurers in the area so that no one could warn the town of his plans.

Yukitoshi managed to assemble an army of 60,000 monsters and headed for Ur but was stopped by Hajime and his companions (now including Tio, who earlier was freed from Yukitoshi's control thanks to Hajime). He was later dragged by Hajime back to Aiko as per her request in the hope that she could rehabilitate him. Unfortunately, after spilled his plans, the non-restrained Yukitoshi managed to grab Aiko and threatened to kill her with a poison needle from one of his monster minions and demanded Hajime to give him his power Artifacts. He was about to kill Aiko, but was stopped by the intervention of Hajime's companion Shea. Though failed to snipe Yukitoshi and Aiko from far using water spell "Rupture" due to Shea's intervention, Reiss still managed to land a mortal wound onto Yukitoshi. As Yukitoshi laid dying, Hajime approached him, told him that he could render aid, but he first needed to know if Yukitoshi is his enemy. Yukitoshi replied by promising Hajime that he would serve him and use his powers to grant him whatever he wanted, be that an army of enthralled monsters or brainwashed women. Hearing this only confirmed Hajime's belief that Yukitoshi has stooped so low he is beyond redemption and repair, Hajime proceeded to kill him with a shot to the heart and the head each.

That’s why I wanted to prove my worth to all of you..."

Trivia

 * Yukitoshi was the first member of his class to be killed and first to be killed by another classmate (Hajime).
 * Hajime has speculated that the reason the demons first recruited Yukitoshi was because they actually viewed him as the greatest threat within the Hero Party since he had the power to control monsters and could potentially steal their own monster army if he remained on the side of the humans.
 * This also ironically proves that Shimizu is indeed special, as his unique job class and skills could have had a major effect on the outcome of the Human-Demon War depending on which side he had chosen to side with.
 * Yukitoshi's wound from Reiss' snipe was bad enough that he would have die even without Hajime having shot him. The reason Hajime killed him was for Aiko not to blame herself for Yukitoshi's death.
