Mobile Suit Gundam 0083: Stardust Memory - The Mayfly of Space

Cima's past is explored through flashbacks in Mayfly, which takes place before the events of Episode 13. She and her unit were ordered to poison a Side 5 colony using G-3 nerve gas, which led to their ostracization by their own countrymen. The aftermath of the war left Cima and her men without a home, as their colony Mahal had been converted into a military asset, and their superior refused to grant them safe passage to Axis.
