June 1582, Mitsuhide prepares for battle at Horagatouge pass when he learns Hideyoshi's forces have retreated from Takamatsu. Mitsuhide then realizes he's been used by Hideyoshi. The armies will clash near Kyoto at Oyamazaki. June 12, Ieyasu decides to go assist Mitsuhide with 15 000 men. June 13, Kiyohide's armies controls Mount Tenno and Koizumi river. They are the rear-guard of Hideyoshi's forces. Takayama occupies the vanguard. Hideyoshi arrives with Hidenaga, Nobutaka, Niwa. When asked to hoist a revenge banner, only Ueda Satarou who is struck by the peculiar design is willing to. Satarou is known for killing Mitsuhide's son Tsuda Nobusumi. Takayama is having a dish he learned from the Portuguese. Attracted by the fumes, Sasuke joins him. Needing additional vigor, Sasuke drinks an overly large and strong tea he brewed in his helmet. The display is witnessed by Satarou. Hideyoshi's forces number 40 000 men. They overwhelm Mitsuhide's 15 000. His only chance of winning is to take Mount Tenno. Knowing it will mean his death, his faithful retainer Saitou will undertake the task. The battle starts: Yasuke saves Sasuke and tells him the killer of Nobunaga was Hideyoshi. Sceptical at first, Sasuke realizes this must be true. But he soon forsakes revenge for survival.
