Tawawa

I once even had a demonic nickname on HeroesWorld.

Yeah, there are quite a few people here who are into the theme, you can even tell from other things at the masquerade. The problem isn't about understanding that you're interested in it, but about cutting off other local villain enthusiasts and Warlocks from the topic.
Well, and yes, the logic of Siva with FGO is one of the few that works in such a case...
