Kannagi: Crazy Shrine Maidens, Vol. 4

Nagi is a goddess who wakes up from years of slumber with the help of a young boy named Jin. He accidentally cuts down her sacred tree so her powers are diminished, but she resumes her quest to rid the world of its impurities. However, she has another personality inside of her - Kannagi - so Jin gets two roommates for the cost of one when he lets Nagi move into his house!
