Haruna Kisaragi  

Haruna is Yui's best friend, known for her polite, calm, and caring demeanor. Her exceptional intelligence and affinity with computers make her an ideal candidate for Corrector, as predicted by Dr. Inukai. Initially, she was intended to be a Corrector from the outset, but due to IR's confusion caused by Grosser's intervention, Haruna was mistakenly identified as Yui. During her tenure as Corrector, Haruna was manipulated into becoming Dark Angel Haruna under Grosser's control. However, she was eventually rescued by Yui and returned to assist her in the 2nd season. In this season, Haruna proved more adept at using Element Suits than Yui, particularly when Yui was petrified by infected insects and later throughout the series.
