Jiyuujizai ni Ero Saimin: Dame Dame no Ore demo Bishoujo Taimashi to Yarimakuri!

Things always backfired for Rick Kamisawa.

That looked like it might change when he was invited to the Urban Legend Club,
a hangout for cute girls who really liked demons and occult mysteries,
but it turned out to be much more than that. The girls were Exorcist Knights,
and Rick was recruited for his uncanny demon magnetism.

He was bait. How disappointing.

Things always backfired.

While he adjusted to life with the Club,
Rick found a discarded book called "The Tome of Seduction".
Like many urban legends lately it proved that mind control was real,
and that minds could be controlled if you knew the right steps.
With this book, Rick saw the potential to warp the reality around him.

He was no exorcist, but he could be a hypnotist...
master over his teachers, his classmates, and the beautiful girls of the Club.
