3

Chihaya and Kagetsuya infiltrate Dr. Ashino's lab to rescue two black angel children held for interrogation. While searching, Chihaya finds a dormant black-winged angel named Messiah wired to the walls. Chihaya exposes his wings to attract attention, causing Messiah's memory chip to record the transformation and generate strange emotions. Messiah attempts to approach through the glass but remains trapped. An alarm sounds, forcing an immediate evacuation as the lab prepares to explode. Kagetsuya carries the rescued children, and their mother Elvira helps them escape in her car. Chihaya remains troubled by his failure to save Messiah. Later, Chihaya sees news of Dr. Ashino arriving in the city with a man in a trenchcoat, whom he recognizes as Messiah. Ashino, commissioned by the military to create the ultimate weapon, seeks revenge on the world for abandoning him after Taki left him.
