Fan:Jeri Hikari

Jeri is the same age as Ian and plays as a older sister figure to all the human members of the army. Jeri has a crush on Ian and often tells him some of his ideas are crazy, but that's in a way just Jeri's way to tell Ian to "Go for it". Some of the members on Blue Xros Heart call her and Ian "Xros-Twins" due to the fact their birthday is on the same day.
