Yukitoshi Shimizu

Yukitoshi Shimizu is a character from the "Arifureta Shokugyō de Sekai Saikyō" series.

He was a member of Aiko Hatayama's bodyguard, but later betrayed them and joined hands with the Demons.

Appearance
Yukitoshi is a young man with black hair and black-eyes.

Personality
He was an isolated person who didn't have any friends so he was described as a mob character. He always was reading books in his seat while he never talked to others in anything louder than a mutter. This was 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 outcast personality he became a habitual truant and constantly had dark thoughts floating around in his mind about his family and classmates.

Background
Yukitoshi Shimizu was an otaku but he hid the fact to avoid the kind of treatment that would come from it, having seen how Hajime was constantly bullied for it. After being transported to Tortus he was exited to be a hero but had his spirits crushed when he found out he was no more than a side character. He took up the opportunity to travel as one of Aiko's bodyguards in order to experiment with his monster subduing magic.

Plot
Yukitoshi was approached by demon named Reiss while he and the rest of Aiko's guards were at the seaside town of Ur. He requested that Yukitoshi subjugate the town and kill Aiko for the demon kingdom. Yukitoshi agreed due to Reiss' promise of being treated like a hero in the demon kingdom. Yukitoshi fled to the mountains in the north to gather and army of monsters for his plan. 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 Nagumo and his companions (including Tio, who was freed from Yukitoshi's control thanks to Hajime). Hajime brought Yukitoshi back to Aiko as per her request in the hopes that she could rehabilitate him. Unfortunately, Yukitoshi managed to grab Aiko and threatened to kill her with a poison needle form one of his monster minions. He was about to kill her, but was stopped by the intervention of Hajime's companion Shea. It was then that Reiss appeared and mortally wounded Yukitoshi with the water spell "Rupture". As he laid dying, Hajime approached Yukitoshi and told him that he could heal him, but he first wanted to know if Yukitoshi was his enemy. Yukitoshi replied by promising Hajime that he would serve him and use his powers to grant him whatever he wanted. Hearing this confirmed Hajime's belief that Yukitoshi was beyond saving and killed him by shooting him twice (in the heart and the head).

Skills

 * Magic Master - Yukitoshi has an incredible aptitude for dark magic. Dark magic is able to influence the target’s thoughts and perception. In combat, its main purpose was to debuff enemies. Yukitoshi quickly grew proficient at creating illusions to disorient foes, interfering with their ability to cast magic, and even making them hurt themselves in confusion. His talents in the art grew to a point that he could control the minds of monsters. Despite his aptitude for it, however, he couldn't control the mind of any intelligent beings unless he cast magic on them for a day and without any resistance.
 * Language Comprehension - a base skill granted to all those who got summoned. It gives the user the ability to understand any language and be proficient in it.

Trivia

 * Yukitoshi was the first member of his class to be killed and first to be killed by another classmate (Hajime).
