I read some time ago that he is the one who reversed the time, because he was in love with her the first time. That's why he keeps dreaming with her. How was he able to do that? I don't remember, but it had to be related with the demon king or something after he defeated him the first time.
Yeah. Claude eat demon's king heart. That is why he possessed some black magic and the holy sword rejection him
Wow I knew it!!! When I thought about this-- the fact that he was the one who turned back the time-- I really thought that what I was thinking was gibberish but dang, I hit the jackpot lol.
Thanks for the spoiler!
Woaaaahh what a great plooot. Thanks for the spoiler
What happened to Claude?? Why is the holy sword rejecting him? Is it related to power he received when Ivona's in danger because of her first attempt in getting the pillars magic????
