Akechi recalls the day she first met Nobunaga, who took a liking to her and showed her a world outside of her workaholic life, asking for her help in conquering the land. Meanwhile, Nobunaga takes Hideyoshi through the inspection tunnels, talking about the good luck charm she received from her grandmother, Nobusada. However, as they prepare to head back, Hideyoshi accidentally activates the security system, filling the way back with deadly traps. Meanwhile, Masamune talks with Akechi, before Nobunaga and Hideyoshi manage to escape from the tunnel. It is revealed that Masamune is actually Hideyoshis teacher, who travelled back from the present after discovering someone that came out of the shrine and then disappeared.
