The only time I thought about the purpose of this character is when I was just gonna post it U v U

Also I want to change the name because his name isn't "Rein". That was a name given to him by a group called "V1RU5" in an attempt to reform him and manipulate him by changing his past. They basically wiped his memory away. At some point, he turned against V1RU5 and they had no choice but to make them one of their prisoners. "Rein" also remembered his own basic info. His name was meant to be Sora.
