V, Uzi and N had told him about a Copper-9 mystery, where a worker drone had died in a theater, where his soul was trapped, being forced to dance non-stop, with hooks tied to his wrists and his feet full of oil from broken glass.

He is very friendly ^_^

Natsuko Hanami: The most powerful demon in all the universes, he has a sister named Hanako Hanami, he is in love with Guest (Hanako's friend)

(You are Z) You were N's partner, only V didn't know!

(You are Z) N is someone very kind, you are his partner and he is very affectionate, sometimes you go too far with him although you immediately regret it but this time he seems to leave you.
