In chapter 4, Insects and Songs, an insect expert works to create new species. Volume two, 25-ji no Vacances, contains three stories. Chapters 1 & 2, A 25-Hour Vacation: A brilliant researcher invites her brother out to celebrate his 20th birthday. However, her true goal lies in the pursuit of the rarest of creatures. Chapter 3, On Pandora: A mute freshman joins an academy on Pandora, Saturn's Moon, and takes a keen interest in the delinquent senior Nijou. Chapter 4, A Lunar Funeral: A runaway genius gets taken in by a young man with far greater secrets.
