Ittsu

Sagami was dragged into sneaking into the high school that he and his two other friends were attempting to be accepted into after they graduate from middle school. While sneaking around, observing the high-school girls, Sagami noticed one girl that stood out. It was love at first sight. He took a picture of her with his cell, and now uses it as his "reward" for studying harder to get into the high school. Due to this "reward" system, he successfully got accepted into the high school where the girl of his dreams attends. Now, an odd and awkward high-school love life begins for Sagami

Tsuruoka Itto, unmarried at 32 years old, just started a job as the janitor at an all-girls' high school, where he's found the girl he's sure he's going to marry, Asahimura Sayaka. When he hears a scream out behind the school one day, he finds Sayaka-chan fretting about a frog inside her clothes, a problem compounded by her frog allergy which soon causes her to faint. Neither the teacher on the scene nor Sayaka's friend will touch the exotic-looking pink frog for fear of poison, which leaves Itto to put his body on the line to save Sayaka-chan. When he finally manages to fish out the frog, it's latched onto a cut on his finger and sucking his blood. Itto in turn soon faints from blood loss, and when he wakes up, he's going to find himself a whole new man...

Though he doesn't know what to think, one thing’s for sure, Hideo’s life just became anything but boring.
