Asakusa...the City is filled with Shinobi who work secretly away from the public. However, each of them has an secret: they're in relationship with boys!
Witness the life of the Shinobi and their boyfriends as they live crazy adventures together. Between fighting Yoma, jealous people, others Shinobi who either want them for themself or want to split them from their couple. Along with several people from the Past who want revenge.
One thing is sure, with a City filled with Adventures/Misadventures, things won't definitively be boring.
