[Shinogi A-suke] Boku Joshikou ni Nyuugaku shimashita ~Bangaihen~ (COMIC Mugen Tensei 2018-04)

The only boy enrolled at Amane Girls' Academy lives as the school's beloved 'prince,' fawned over by classmates and managed by a strict, clipboard-wielding handler who keeps his schedule ruthlessly booked. After a ninja ambush drags him off campus, a breathless love confession from a twintailed admirer turns into a heated, sweat-soaked session while a crowd of jealous schoolgirls watches every thrust. When his manager storms in with the entire waiting list in tow and demands he fulfill his daily quota on the spot, his harem existence tips into overwhelming, hilarious excess.
