PLOT:
Ayumu Kamei and Runa Takishima have always been at conflict in middle school. Regardless of her age, Ayumu was continuously on the losing side, repeatedly being taunted and tricked by the youthful Runa. Ayumu believes that now they’re in high school, she will compel Runa to recognise her.
Even to this day, Runa, who is funny and charismatic, continues to play Ayumu like a tinker. No matter what techniques he ends up playing on her, she always falls for them, so she never notices his true intent. To succeed, she must find Runa’s weakness—but Ayumu is Runa’s weakness!

Tsuki no Oki ni Mesu Mama now has 600.000 copies (including digital) in circulation for vols 1-8. Congratulations to the mangaka and the Bessatsu Margaret team! Vol 9 will be out this Fall.
