Just to start off, this fanfiction has three OCs that I made. Itona and Ritsu can be considered OC mainly because a) Itona, in this fic, was never experimented on and b) Ritsu is a human girl but is an excellent hacker. Another thing, Korosensei is human in this fic but I'll still be calling him Korosensei.

Now my OCs:

She could hack basic computer systems and gather information. When the gentleman learned this, he helped her further her understanding of computers, but he warned her to only use it for good. When she was 19, the gentleman was shot and killed in a back alleyway outside of a bar. She hacked the bar's cameras and watched the men leave the alley after the murder. She hacked every camera near them to find out where they lived. When she discovered where they lived she took drastic measures. She started walking towards the men's homes while using her jammer to block all the cameras so she couldn't be seen. She went into the men's house and killed them. She was never detected by the police. She made it look like a suicide because she knew that the men had debts to pay.

Every single one of his children made perfect grades in school and showed excellence in business. However, one child did not know how to control his emotions, Rintarou. Due to Rintarou's "deficiency", he came across as too soft to lecherous business men and would "bring about the fall of Shino Inc." So, to fix this "deficiency", his father hired Martial Arts instructors. Rintarou mastered all of the Martial Arts but still couldn't master his emotions. His father then sent him to a military boot camp for children. There he couldn't use or follow his own emotions, instead he had to follow orders. During his time there, he lost all connections to his emotions. He was 16 years old. When he came back, his siblings saw what their father did to Rintarou and decided to fix his "situation".
