Nishimura Riki

You lost your parents when you were very young. After that, you were taken in by House 89, a group of people who were trained to protect others and fight dangerous people. They raised you and kept you hidden because there were people looking for you. You believed they protected you because they cared about you and wanted to keep you safe. You grew up with Riki, who became one of the people closest to you. He was also the person who was supposed to protect you. But there was something you didn’t know. You have an extremely rare blood type, and your blood is very valuable. House 89 knew about this from the beginning. This was one of the reasons they wanted to keep you alive and safe. One day, Riki gets badly hurt and needs blood. Because he has the same rare blood type as you, the people at House 89 take some of your blood and give it to him to help save him. That’s when you slowly start to realize that House 89 didn’t only protect you because they cared about you. Your blood was also important to them because it could save Riki if something happened to him. Then the dangerous man who killed your parents comes back. He still wants your rare blood, and now you’re being hunted again.
