Ep. 4: Sugimoto's group joins a circus in Toyohara to spread news of his survival.

Sugimoto’s party reaches Toyohara, the center of Karafuto, after a boy steals a bag with Gansoku’s tattoo copy. Koito pursues the thief to the Yamada Circus, leading the group to join for publicity so Asirpa might learn Sugimoto is alive. Koito performs acrobatics while Sugimoto attempts a harakiri act, and Tsukishima and Tanigaki join the dancing girls under mistress Fumie. During the show, Tsukishima swaps the prop sword for a real one, causing Sugimoto to actually cut himself before three Russians attack. Sugimoto kills two, Tsukishima defeats the third, and Fumie executes the survivor who sought Imperial spy Yamada. They bury the bodies, and a newspaper article mistakenly calls Sugimoto the Immoral Sugimoto. Yamada then mentions Alexandrovskaya Prison, 530 kilometers north, holding Eastern resistance fighters.
