Month 3 The train driver who tore the armor, the boy in a wheelchair holding up the train, the female master who rubbed the flesh and blood mecha with her hands...

- "Conductor's Log" We crushed the tide of corpses with steel wheels, connected the broken tracks with supernatural powers, set up flamethrowers in the plant frenzy, and when other survivors begged to get on the train, my attendant was baking cranberry cookies.
