Overrated. Prodigy dies, gets reborn as prodigy, does prodigy stuff with minor difficulties along the way. The end. Female lead acts cute even after she's old enough that she should really contain herself. Plot, predictable. Character's personalities, typical. Setting/costume design/music looks like watching game avatars from free 3D MMORPG games. Action scenes, okay I guess.
It's an OK watch if you're bored. There are more exciting/original anime out there to watch though.
