Teacher Sorata Muon carries on his family’s centuries-old old tradition of being the master thief Mouse who can steal anything after properly alerting authorities of his intentions so they can be there yet fail to stop him. He is assistedby 3 nubile female assistants who also use the teaching cover and who, in typical Satoru Akahori, favor tight/skimpy/bondage outfits over their ample curves as they constantly pursue Sorata much more than he pursues them, although the girls do get some attention from their master.
