I still think that Euclid is creepy as hell being such a sis-con but I can't talk either because Serafall and Sirzechs are the same way as well but Euclid might be pushing more to the extreme than her.

I noticed that in Dxd the more powerful you are the more weird and strange you are with your personality and traits good examples are Sirzechs and Serafall maybe is a trait of Powerful Devils.
