Narumi awakens in an Illinois hospital with amnesia and a prosthetic arm, saved by Guy Christophe Resh. The hospital, run by Dr. Banhart, houses 2,000 children with Zonapha syndrome, where staff smile to prevent attacks. Narumi learns terminal Zonapha patients linger between life and death. Resh reveals the Midnight Circus uses automata to spread Zonapha and asks Narumi to become a Shirogane. The last Aqua Vitae healed Narumi. When Paulmann and Anselmus attack the school, Resh uses his Karakuri Olympia, and Narumi helps defeat them.
