Though in anguish for losing his mentor and hating the ugliness of war, Ranmaru continues to fight to honor Mitsuhide's wishes. Entrusting his pupil to continue believing in their lord in his place, Mitsuhide dies in Ranmaru's arms. If Ranmaru chooses to slay his mentor, Mitsuhide reveals that he betrayed Nobunaga due to him being envious of Nobunaga's power. Strengthening his resolve to defend his lord, Ranmaru simultaneously struggles to consider his mentor as his enemy and wonders if he should kill him. Additionally, Masamune, Magoichi, and Keiji utilize the chaos around them to strike against Nobunaga. Mitsuhide flees from his defeat and allies with Ieyasu at Anegawa. Although Noh defects and dies, both Nobunaga and Oichi escape safely due to Ranmaru drawing the entire Akechi army to his position. Ranmaru bravely defends the southern gate of the temple to defend Nobunaga's escape with Noh and Oichi.

Sympathizing with his mentor's retreat from the field, he stands against Mitsuhide's betrayal undaunted at Honnōji. Following his mentor to Ise-Nagashima, Ranmaru partakes in the massacre of the peasant army. Therefore, they have their wish granted and soon cause the end of the Saitō family. Their capable defense drives the Oda back momentarily and impresses Nobunaga. Losing faith in their leader, however, both men decide to prove their worth against the Oda at Inabayama Castle. He is Mitsuhide's pupil and they both begin their services in the Saitō clan. Ranmaru is a young man who believes in his lord. ~~ Huang Gai Warriors Orochi 2 Samurai Warriors ' With you around, my peaceful retirement isn't just a dream.'
