Lovemare

Kabuki Shun is a perverted high-schooler loathed by every girl in the school, including his childhood friend Sakura. One day, however, he saves a strange, simple-minded girl who calls herself Lovemare, the Missionary of Love. After he shows her all the perverted manga he drew about his female classmates, Kabuki is suddenly transported… into the world of one of those manga.

As it turns out, Lovemare has the power to turn all of Kabuki's fantasies into reality. And thus his daily life becomes a paradise… except maybe not.
