Ryumi (Myotomi Ueshishi) and Totaro (Masao Takasugi) participated in the legacy division agreement for the old family, but there was a problem with chess in Kaifeng's suicide note!The children, led by their eldest daughter, Kirichi (Uchiyama Riki), also had disputes, and they developed into quarrels between brothers and brothers!?

It seems that this clan hates chess, and there seems to be a reason.Unheard of before, the last words of the chess are interpreted!In addition, Ryumi and Totaro live in a nearby hotel, worried that Ryumi's father Tatsuo (played by Seiichi Tatsuya) and mother Kasumi (played by Emiya Kasumi) also arrived, and the situation was unexpected!
