Our take on Secret Agent

The defining setup is an undercover ninja trainee investigating academy incidents while an accident exposes his identity, turning the mission into a conflict between secrecy and relationships.

What is Secret Agent?

Secret Agent is a Japanese-style romance visual novel about Mikage Jin, a young ninja trained by a family tied to national security since the Edo era.

Jin enters Touka Academy under cover to investigate incidents linked to a figure calling themselves the Bat. An AI partner, Momoka, assists while Jin builds relationships with classmates and academy figures including Kanon Mayfield, Shirogane Kagura, Renjouji Main, and Amenomori Yui. After an accident reveals Jin’s identity, the mission becomes harder to maintain. The story follows whether he can continue the investigation and complete his assignment after his secret is exposed. The central setup combines undercover school life, romance, and a ninja-family background.
