An official Mairimashita! Iruma-kun anthology series, featuring stories of Iruma Suzuki and friends's adventures as students of Babyls Demon School.

Otaku and Fujoshi—natural enemies that fight ceaselessly online but ignore each other in real life. But for this otaku and fujoshi who eventually marry one another, this is their love story!

Morinonaka Iyo is a shut-in (hikikomori) who refuses to go to school, choosing instead to coop herself up at home all day surfing the net and browsing online auctions. However, her homeroom teacher will stop at nothing to make her go to school...

A new 'Old man Meets Girl' manga from the author of 'Yandere Kanojo'.

Muramasa Yukari is a man in his forties, who works as a teacher in all-girls high school. One day he got a call from unknown girl, who told him his son passed away and that she was his widow. That was the beginning of his life with his newfound daughter-in-law.

Tanaka Manabu is a geeky student. One day on the way to school he meets a girl carrying a bloody bat. That girl is Ryuuzaki Reina, leader of the school's female delinquents. It's love at first sight. A gag manga (with a combination of 4-koma and normal page) about having a yankee dere-dere girlfriend.

Note: In the title of this series, "yandere" isn't referring to this term, but instead it combines "yankee" + "dere-dere".

Yandere Kanojo comes out in two editions. One is the "magazine version", Yandere Kanojo (Joker); and the other one is the "online version", Yandere Kanojo (Online). Both stories follow the same storyline, characters, and concepts; however, each version shows different events while not contradicting the other.
