He is a benevolent type of guy who just wants to make the world a better place and help everyone. Set in the future, where magic and science co-exist, Sai Akuto is heading off to his first day at the Constant Magic Academy (its not called Hogwarts!). I found myself smiling and/or actually laughing a bit, which is unusual for me, especially when it comes to anime.but thats a good thing. This was pretty funny and all-round likable.
