Looks like a winner to me. Well constructed, nicely paced. I enjoy the main characters. Maou-sama's quick assimilation of facts is a good thing both for his survival and for the drama. The idea of being able to hypnotize people into doing what you want is a classic. Works for me.
Here's a brief quote from my
season preview: "...Director Hosoda Naoto did
Shuffle and
Mirai Nikki. Writer Yokotani Masahiro has been lead writer for
Keroro Gunsou, Reideen, and
Busou Shinki (how's that for range, lol?) Interesting cast features Ono Yuuki (Zenkichi in
Medaka Box) and Ousaka Ryoutarou (Eita in
OreShura), with Touyama Nao, Hikasa Youko, and Itou Kanae."
