I see potential in Kei. His ghost is bloodthirsty and he can't control it quite well atm but he must have a unique skill that no other Ajin haves. Can't wait for we to figure out what it is :T_T:
I loved Kei's expressions in last two episodes when his ghost started randomly talking. hehe
For now, I just love Kei. I love his selfishness, I love his coldness, I love his inteligence. However, I am afraid that Kei is gonna change... Wait, do you read manga?
And manga is pretty much still very young... There are so many things we don't know about all characters. We basically just scratched the surface.
