第 4 集: 萬次郎與鈴尋求索里大師協助，向一文字流復仇。

4

Manji and Rin visit the famous swordsman and artist Master Sori to enlist his aid for revenge on the Ittou-ryuu. Rin tries to convince him to join her, revealing that she is aware that he is a spy for the shogunate. He admits that he only supports the shogunate so he can pursue the forbidden Western art style and Manji storms out of the house, disgraced by his excuses. Rin wakes from a dream, to find Sori's house surrounded by followers of the Ittou-ryuu. Manji tries to fend them off but is trapped against spikes on a tree. Master Sori, looking for a shade of red to complete his drawing, is overjoyed when a stray drop of blood provides the color he's looking for. Rin unsuccessfully tries to fight off one of the followers, and just as she is about to be killed, Master Sori stabs the follower through the throat. Anotsu kills the remaining two followers on their return to Ittou-ryuu for disobeying the rule of one-on-one matches. Master Sori comments how similar he and Manji are, and later gives Rin a sack of money as payment for providing the right color to complete his masterpiece. (Source: Wikipedia)
