Even though this was the coolest anime ever but the ending wasn't what I expected, the ending was saying that Takuma was hurt and was starting to turn to a demon and that Tamamki came and helped him to kill the demon and the Logos people left after the fight and after that shot the anime was finished. What I expected was that Takuma and Tamamki would be together since they match a lot but they didn't and that they didn't say much about the extra guy with the dark grey hair but I do like the drawings of the anime characters.
