Fufu, it's not my fault humans have simply chosen to worship me under so many different names. I use Faust and Mephisto equally both here and back home -- so call me whichever you'd prefer.

[He doesn't really have a preference, so long as it's not inappropriate for whatever company they're in, such as calling him Samael in public, or disrespectful... like Sammy.]

[But then Chuuya goes and says that-- and right away, Mephisto is curious.]

...you told me you were fused with an ability. You never told me it had a name.
