...this is my theory. Charlotte defeated the Devil, but before disappearing he managed to make it so he could revive to get back at her in a love/hate kind of way... was born as a human boy, unaware of his past (Evan). He's got tons of magic so Charlotte takes him in as a disciple, who's immediately obsessed with her because love/hate from past, but since he's a child the love part wins out. He's mischievous from the start because, hello? Devil!! When Charlotte "dies" (she couldn't die as she was too powerful or the Devil had cursed her to be reborn... many theories on that one) he can't accept it and goes looking for her or ways to bring her back, in that process he awakens the Devil inside him who starts taking over his intentions. With the Devil he manages to find her. He needs more power to awaken so he starts all these weird processed using humans to do his bidding and with the help of demons that recognize him as the Devil. However he cannot let them harm Charlotte whom he's obsessed with even more than before because Evan's feeling have developed quite strong. - Endgame I think is they will have to cancel each other out. Charlotte will have to take out the Demon along with herself. Kicker is the Archduke, though injured and weak will still be alive so ppl will wonder if she's really dead or pulled off a rebirth again. the end ... I'm most likely off but that's what I think.
so actually chivalry had women standing to the right of the man/knight, because a righthanded swordfighter (and they could only be right handed) carries his sword on his left hip, and needs to un-sheath it from the left side and as it comes out it makes an arc and it risks smacking or cutting whomever is standing to their left side. So she should most definitely not be standing on his left side.
ok I'm sorry Ledalia's an idiot.
