If you guys are looking for something new to read, do yourself a favor and read this series. It's a nice series with great action, mystery, story, plot twists and more. You won't find one plothole or inconsistency. It's the sequel to Negima, but it's stated in the description that you don't have to read Negima to get into this series. You can read Negima afterwards if you want. It has 355 chapters.
The setting is in a world filled with immortals, mortals, ghosts, Exorcists, beasts, etc with advanced modern day technology.
It's starting to get popular in Japan. Hopefully an anime comes out in the future.
