Pink Dark Boy Fan Brothers

Two young brothers who are deeply engrossed in reading Pink Dark Boy at S City library's reading space. Rohan Kishibe overhears them debate how best to continue their marathon of the series. One brother worries that someone else might check out the volume before they finish, while the other reassures him that the library has multiple copies. However, the first brother explains that each copy has different yet connected stories, making it crucial to read as many volumes as possible. Realizing that their borrowing limit is five books per person, they devise a plan to check out ten volumes together to maximize their progress.
