Chan Agi

Chan is a technical officer for Londo Bell who helps Amuro supervise the development of his ν Gundam during the Second Neo Zeon War.

Her relationship with Amuro earns her the wrath of Quess Paraya, who calls her a "disgusting hag" and ultimately betrays Amuro when he attempts to stop Char Aznable before he carries out his plan to drop the Axis asteroid onto Earth.
