Synopsis

Shirone experiences a bizarre situation where familiar faces at her school act like they don't know her, prompting a sense of surrealism and the suspicion that she might be dreaming. Simultaneously, other students and a professor discuss mass, its creation, and the nature of existence, culminating in the idea of a 'God's Particle' associated with the feeling of will to exist. The chapter also shows Shirone reflecting on her time at the academy and her relationships, before being confronted again by the seniors who still act as if they don't know her.
