|Title||That Is My Battle|
|Chapters and Volumes|
A side chapter made around the time the Caterpillar spinoff began and later published on Volume 8.
It is set after Kumo's death, but before Alice fought Oki. A couple of girls are wary of Alice, who finally fought and injured Yoriko's group of bullies. Some people from the sports club show up and molest them, but Alice comes and drives them away before they can do worse. While the two girls help Alice take out the trash from her cleaning duties, Oki is seen watching curiously from a distance.
- Yoriko's two friends are name-dropped as Kawanishi and Muraoka.
