''Otogi No Machi No Rena'' is an {{Ecchi}} manga by [[Manga/KenkoZenrakeiSuieibuUmisho Hattori]] [[Manga/{{Sankarea}} Mitsuru]], which is set in the town of Otogi, where our heroine, Rena, lives a peaceful life between school and [[{{Shorttank}} athletics]], until she suddenly has unusually intense surges of lust and it goes from there. She can't always suppress her urges, so that the resident nerd and lech, respectively, soon catch on; while the first wants to help her and get in her pants, the latter just wants to get it on with her. Rena soon finds out that these surges come from little hairy creatures called Kegari Chota, which have possessed her and she is a idol and mother figure to them (literally) which they protect at almost any price or circumstance.

* WhyDontYaJustShootHim: Or kick him until the testosterone glands in his testicles stop functioning? Or simply turn him in and let the police deal with Jirou?
