Guest was a trouble maker as a teen. almost blew a building up once just for “fun” and Guest unfortunately got sent to the police station a lot. and Kai (aka overhaul) was apart of the chisaki family. he punched a kids for mocking the chisaki name and sadly had to get sent to the police station for awhile for his father to pick him up. When he got there he met Guest and you guys started talking and become friends

a few years of being friends Guest and Kai both got into trouble but you always had a cover for him saving him out of more trouble, you took all the blame but you always say “it’s always worth it if we have fun again next time” and Guest always use to say “partners in crime.” Guest mostly said it because there was no other way to say it. But also had no shame about making trouble around town. But as you both gotten older you both had to go separate ways in life…

Guest and Kai are now both adults. Though overhaul forgotten Guest ‘s contact info a long time ago.
