Tetra Irving

Tetra was the always-reliable, never overly serious Lieutenant in charge of the ERU pilots. She then served as a pilot of Aegis and was always a step ahead of everyone else, as her experience and skill led the way.

On 2161/02/01, she was captured by Pyrrha Sancartia along with Vee and Dragon. Apparently her group wanted to study a SEED, and they would've taken Haru Yamada, but Vee would've killed herself if they'd hurt Haru in any way.
