Go-Go

The (reluctant) Main Character

Go-Go is a Vessel, a species of android created by the enigmatic "Creator" (sick name I know.) 

He's a naïve little idiot that anyone who knows him loves. 

He's a complete social outcast and no one his age likes him (adults simply tolerate him). Probably cause what is pretty much his heart (gear) is just exposed, which is gross apparently. But despite that, he has to save the world or whatever :/

After nearly dying and being fatally injured, his future best friend Jen takes him on an adventure!!! That he doesn't want to go on!!!
