Kure-nai

After approaching Benika to request more challenging and rewarding jobs, Shinkurō is assigned as a bodyguard to Murasaki. The next day, Shinkurō goes to school, leaving Murasaki alone in his apartment. When he returns and she is missing, he begins frantically searching the neighborhood. After searching for a long, Shinkurō finally finds her, crying alone in the dark. Shinkurō comforts Murasaki by hugging her, which signifies the beginning of their bond.

While Shinkurō is at school, Murasaki meets the other inhabitants of the apartment building. In the evening, Shinkurō takes Murasaki to the public bathhouse, and then buys her a new futon. After Murasaki is asleep, Shinkurō goes out on another assignment as a negotiator and finds himself in a violent confrontation with thugs who are threatening the owner of a local restaurant. Shinkurō realizes there is more than meets the eye.

Murasaki appears at Shinkuro's school and wanders around, investigating high school students' life and culture. She also ends up meeting Yūno Hōzuki, who she already dislikes. Later at night, Murasaki discovers Shinkurō has snuck out and follows him. She gets caught up in the middle of a violent confrontation and gets hurt. As a result, Shinkurō goes berserk and quickly cleans up the scene with the Hōzuki horn. Murasaki wakes up the next morning and offers Shinkurō breakfast to apologize for interfering with his job.

After the incident at the yakuza's office, Yayoi demands to know why Shinkurō is given the job of protecting Murasaki. Shinkurō's background comes to light as well as the reason why Benika helped Murasaki escape. It also shows why he has a lot of respect for Benika.

Murasaki and Shinkurō go to the Hōzuki household so Shinkurō can train with Yūno Hōzuki. Murasaki interacts with Yūno's little sister. More is revealed about the Hōzuki family and Yūno turns out to be a very competent martial artist.

All four apartment tenants are practicing for a musical, which will be held during a community festival. Yūno is recruited but it turns out that she's tone deaf and has Shinkurō practice with her. Yamie gets Yayoi to help her with her singing.
