Run Jet, Run~

My OC: Jet

Here I have in my post today is Jet
a 28 year old scientist that is specialized in inventions
but due to certain events, he has developed blood thirst to use living human bodies as his test subjects...

an expressionless guy
lives in an underground cave
doesn't usually go out except to search for materials for his invention
the only thing that intrigues him is when doing experiments
he can go on a whole week without sleep just to invent something or test his inventions on subjects...

zere u go Kaizen-dono :D
