Aired on April 17, 2002

Itsuki experiments with music to cultivate plants, but a recent violin piece by Quon produces unusual results. Ayato detects dissonance in a recording of Quon’s performance. Futagami recounts how a subordinate soldier used a fusion bomb in Japan during the Mulian war, destroying a city. Kunugi takes a day off and boards a cruise to meet his wife, whom Ayato and Megumi mistakenly believe is his daughter. She informs him she is leaving Japan soon and provides the final page of a song Quon dedicated to him. Kunugi then visits Quon at a cemetery, requesting she play the composition to honor his daughter Michiru, who died in the Mulian war.
