Synopsis: Yonin no Nibiiro

While walking down the street, Yu notices a person draped in a fur coat who is completely naked. Expecting the individual to be detained by law enforcement, Yu seizes the bizarre unclothed man and takes off on foot. Unbeknownst to him, he has actually laid hands on something that belongs to the yakuza. Reality soon catches up with him, literally, and he finds himself in the midst of yakuza territory. Hot-tempered Makoto asserts his dominance, as usual, while his half-brother and right-hand man, Ai, remains composed and handles the aftermath. As the complications and relationships between the yakuza gradually surface, Yu finds himself stepping on a landmine. But how far will the repercussions extend?
