- This chapter depicts Rina's friends slightly differently from "Gravel Wasteland"—the long-haired friend wears a different hairclip, has a piercing on her right ear, a larger chest, and doesn't have hair falling in front of her shoulders, while the short-haired friend has a different kind of flower in her hairclip.
