At first I thought that it was going to be like The World God Only Knows where Kucabara will be doing one contract after another. But then the story completely went off it's mark. He was no longer doing his Defense Devil but something else.

The character was typical too. The main protagonist as the "Naive" and innocent shounen, the main heroine as a Tsundere, and with both of them having experience tragedies in the pass.

Overall, a redundant manga but still a good manga.
