Yakuza no Oshigoto

Ken Kanashiro is one of the top lieutenants in the feared yakuza outfit the Washio Clan. He lives his life by the code of the Japanese underworld, where nothing is more important than loyalty, and ties between soldiers and their aniki are sacred bonds. Ken’s never had time for hobbies... until the boss’s only daughter Megumi drags him to a K-pop concert, and he sees the glittering, charismatic Jun for the first time. Smitten like a new recruit on his first job, Ken plunges into fandom with the solemnity and passion only a true man who walks the way of the yakuza could muster.
