Trama
Sugimoto's and Hijikata's groups secretly tunnel into Abashiri Prison and link up with Chief Kadokura, an associate of Hijikata's. On a moonless night, they launch the escape plan: Inkarmat, Cikapasi, Nagakura and Ienga wait behind; Ogata stands lookout; Kiroranke, Ushiyama and Hijikata stand by; and Sugimoto, Asirpa, Shiraishi, and Anji enter the prison. They find a substitute in Nopperabo's cell, who screams and raises the alarm. Amid the chaos, Tsurumi and 7th Division attack the prison from the river in warships, seeking both Nopperabo and Asirpa.
