Omamori Himari, Vol. 0

Yuuto Amakawa's ordinary life changed drastically when he encountered a
buxom feline spirit named Himari and was initiated into the world of
spirits and demon slayers! Sure, life with the supernatural has brought
adventure (and danger!) to Yuuto, but it's also considerably ramped up
the raunch factor in his world! And this companion volume of Omamori
Himari will bring more of the same to both series newcomers and
hard-core fans, with a titillating full-color manga installment and
anime design gallery and a comprehensive guide to the characters and
universe of this New York Times bestselling series!
