Onizuka struggles to secretly care for the kitten, Tora, at home, with little knowledge of how to raise a cat. After learning from Kyoko about an available room in a weekly rental apartment, he decides to keep the kitten there. Balancing work, home, and visits to the apartment, he cares for Tora using online research. Even during training sessions, his mind is preoccupied with the kitten. One day, when he arrives at the apartment, Tora, who usually greets him, is nowhere to be found—he spots the kitten collapsed on the floor.
