Sengoku Basara s01e07
Titre original : Robbery of the leadership! The battle under the moon
After her moment with Uesugi Kenshin, Kasuga finds Sasuke nearby and a conversation ensues - mostly consist of teasing and shuriken flinging. It ends when an explosion happens nearby and Sasuke goes to investigate, even though he had a hunch that it's not from Oda's force.
Back in the House of Takeda, Date Masamune is still unconscious and Koujuro is outside his door, holding back his anger of not being any use to Masamune in the previous battle. He talks briefly with Yukimura until Sasuke brings a Date soldier with a letter - some of his men were taken hostage by a shrewd man named Matsunaga Hisahide and he was demanding Date Masamune's swords and Takeda Shingen's armor for an exchange. Koujuro tells all to ignore this threat and sacrifice his men in order to prevent harm to both faction. However, Masamune - who just woke up and heard everything - disagrees with his assessment and decides to save his men. Knowing that Masamune is in no condition to move, Koujuro challenges him and ends the bout by moving into Masamune's blind side and hitting him squarely on his wounds, and knocks him out promptly. Even so, Koujuro decides to honor his lord's wish and vows to bring those men back.
After Koujuro left, Yukimura is questioned by Shingen as to why he let Koujuro go alone. After making Yukimura to see the error of his ways, Shingen orders him to aid the rescue and bring the armor back for sure.
