Lust Geass, Vol. 5 — Osamu Takahashi

There's a new girl in school -- Koyuki Nonomiya, a third-year transfer student with a reputation for debauchery. Bearing a curse from the demon Gremory, a rival of Zepar, she wants in on all the fun, and won't take no for an answer! Faced with an experienced and aggressive partner, Souta finds himself increasingly pulled away from the other girls. Can he deny the pleasures set before him?
