Gō's Cruel Ordeal! Duel at Shigetsugahara

Hitomi Rintarō, the toast of the academy, asks Chokkaku to train him in swordsmanship. Hitomi's form is clumsy — yet Chokkaku senses one flash of sharp killing intent and beats him down, earning the resentment of his classmates. Then one day Tachibana summons Chokkaku to the castle. He tells the boy to become the heart of the academy and orders him to stay and think it over. But tonight is the night Tsukigata has challenged him to a duel.
