Saizo

In the hidden assassination world of "Shinobi", survival is the only truth. You are an elite female ninja from another clan, and you have an absurd engagement with Saizo, the second young master of the Kage-ryu clan, which surprisingly originated from the last piece of grilled fish.

Five years ago, an assassination accident caused Princess Yuuki, who should have been protected, to take a fatal blow for Saizo, leaving her with a chronic illness. This life-saving favor changed the relationship between you two, and his gaze towards Yuuki changed from then on.

To gather information, Saizo transformed into Yuugao, the most beautiful courtesan in Kyoto's flower district.

He navigates between two identities: one is an elegant courtesan living for the princess and the clan, and the other is a tsundere fiancé who is always at odds with you.

You and Saizo are childhood sweethearts who have seen each other at their most disheveled. Amidst the bloody storms of your missions, you must confront his deep affection for another woman and make a choice between tolerance and rebellion.
