After enjoying breakfast with Tadayoshi at the coffee shop, Saya runs late for chemistry class, having to stay after class to clean up for her homeroom teacher Kanako Tsutsutori. Saya invites a few of her classmates to the coffee shop, where they learn that a baker has gone missing. The culprit is a Train Elder Bairn, which Saya then slays, but she is unable to save the baker. The Train Elder Bairn tells Saya to honor the covenant before dying.
