[ENG] Motto! Haramase! Honoo no Oppai Isekai Oppai Spy Gakuen!

The protagonist has two secrets: an overwhelming love of large breasts, and ninja ancestry. When he opens an old scroll left by his late father, he is transported to another world along with his stepsister and stepmother, and lands in an academy where every student, teacher and even the principal is a spy. The principal promptly hands him a mission: find the enemy spy who has infiltrated the school.

Motto! Haramase! Oppai Spy Gakuen! is a fully voiced KiriKiri adventure game by milkfactory (みるくふぁくとりー), released in July 2026, the third of its isekai academy series. It is a nukige with a ninja protagonist and more than seven heroines.

The English patch translates the dialogue and the user interface. It ships a replacement hspy.exe along with the translated files.
