Yakuza vs. Cat

After handing over his title to a successor, Hisahide Matsukata, the former boss of the Onikado-gumi yakuza organization, had been living out the remainder of his life sad and alone... until the day a stray cat showed up at his home! Now at the mercy of the stray cat's unpredictable behavior, the man's formerly quiet and peaceful days completely change! Each and every day is now just as lively and action-packed as when he was part of the yakuza!
