S1E10 The First Boob Hunt: A Hundred Times Three Boobs

Chifusa and Kaede take refuge for the night in a deserted shack as Chifusa battles a fever. During their rest, Kaede brings up an incident from eight years ago when Chifusa suffered a similar illness, a time that led to Kaede becoming her attendant. As memories surface, both Chifusa and Ouka, at Muneyuki's home, start recalling the past. They discover that during a duel eight years ago, Chifusa inadvertently activated the Breast Flow technique, resulting in her stealing Ouka's breasts. Once Chifusa recovers, she and Kaede resume their journey, realizing that there’s still another set of breasts for Chifusa to return upon mastering the technique.
