User Recommendations for Kannagi: Crazy Shrine Maidens

Normal guy + sudden supernatural girl appearance. While Shakugan no Shana has more action, both shows share romantic and magic elements.

A pure-and-sweet boy accidentially starts living with a girl with the supernatural powers. Nagi and Shana are very alike, although Shana has got more of the 'tsun' and Nagi is more 'dere'. You DEFINITLY should watch Shakugan No Shana, if you find Kannagi enjoyable. But prepare for less comedy, more romance and more mystic things.
