Kunihiro leaves to investigate a large fire that erupts in the Sunohara base at night, leaving signs of his departure. The next day, Akiho challenges Iriya to gather information for the newspaper club so as not to be a burden to Naoyuki just before she makes daily call to Enomoto. Followed by a group of four friends including Naoyuki, they soon began food-eating competition as a symbolic competition of their love for Naoyuki, concluding with a three course meal of massive quantity called the Strong Man's Set Meal (鉄人定職 Tetsujin Teishoku?). Resting after they're battle at Akiho's house, they become friends when Enomoto arrives, angry for not being contancted at noon. She returns to school the next day with her hair platinum-blonde and extremely frail. Her vision begins to fail, and in the clocktower of the school, she begins to fountain blood from her mouth; Shiina saves her by sticking five syringes into her body. After finding out that she keeps his things as a charm, he vocalizes his doubts about Iriya's situation, earning him a beating from Shiina. After recovering from his bruises, he decides with Iriya to run away from Enomoto. After removing the bug placed in the right side of his neck, they began their escape.
