新入り(しんいり)の「小太郎(こたろう)」を身代わりに(みがわりに)し、松王丸(まつおうまる)は「菅秀才の首に相違ない」と認めた(みとめた)

To save Kanshusai's life, Genzo decided to cut off the head of Kotaro, a refined boy who had newly enrolled in the temple school that day, as a substitute. The duty of examining the head to verify if it was genuine fell on Matsuomaru, who knew Kanshusai's face. Matsuomaru stared at the substitute head and declared, 'This is without doubt the head of Kanshusai.'
