Hikari is now a full member of the 502nd, but she's not exactly welcome yet. Compared to the rest of the members, she's woefully underpowered, and the trainer isn't sure she should be allowed to fight with them at all.  When one of the girls go missing after returning from a flight, though, she has to go out and find them, and help defend against a Neuroi when it attacks.
