Lieutenant Ninzaburo Furuhata

Dirty King (1x5)

:

During a shogi game called "Ryujin-sen," 8-dan Tonezawa (Yasosuke Bando) attempts to cheat. When one of the overseers, Oishi (Shoji Kobayashi) confronts him about the ploy, Yonezawa kills him and fakes it as an accident. The game later continues as a memorial to Oishi, but Furuhata, who came to inspect the scene, begins to suspect murderous intent in the unnatural scene.
