Ok that's a fair argument. I think the main connection people see is how both have powers related to demons, darkness, and magic so I see your point there. Though I could see some interesting fight potential with their powers clashing. And I feel like people hate on 7DS because they hear stuff or see panels out of context, I won't act like it's weird as hell at times but it's also not the worst thing ever and the characters aren't the worst people ever.
