Ryusuke Mizushima, a semi-professional MMA fighter, leads a double life — competing in fights while working part-time as a caregiver at a facility for people with severe behavioral disorders in the mountains. Through the parallel worlds of competitive fighting and physical restraint in care work, the novel interrogates the boundary between violence and kindness, strength and vulnerability.

The spotlight bleaches everything white. There is only one way to escape from a full mount — from the opening fight scene, the physical and psychological weight of being pinned is rendered in precise, unrelenting detail.

A story centered on Makoto, a practical training assistant at a commercial high school, and Runa, a second-year student there. The two, each struggling with frameworks of femininity and masculinity, come together amid the school's relentless unreasonableness. Standing between school and student, the work explores the absence of easy answers that binary notions of understanding cannot capture.

"So which one of the LGBT letters are you, anyway?" The school where Makoto worked was filled with injustices impossible to resist.
