A thoroughly powerless Towa finds herself at the mercy of Zero and Nanahoshi, who attempts to strengthen his extraordinary powers by feeding on the Half-Demon Princess' enduring sorrow and unpredictability by using an eternity bug on her, giving Zero a greater advantage. Setsuna, still human, trusts that Hisui and the other demon-slayers to take care of the snow demons who are after her. Meanwhile, Moroha continues her efforts in completing the job her parents began and restore Takechiyo to his rightful place in the Raccoon-Dog Clan as well as finally pay off her entire debt to Jyūbei the Corpse Dealer. But Moroha declines, saying that bounty-hunting is her life now.
