Taimashi to Mahou Shoujo (4) ~Koisururei to Inari no Tsuma~

One month ago, exorcist Kaoru Okumoto was hired to investigate
the nature of a major spiritual force in their hometown and he met
Karen who ended up calling him father for some reason.

This time, Kaoru wakes up to find someone latched onto him.
That someone, is what looks to be Karen's mother... Hasuna.
