Aestivalis pilot and rabid Gekigangar III fangirl, she was ejected from the L2 colony in a capsule which crashed into the Nadesico; making her way through the air ducts, she was directly over Akito's room as he was watching a tragic episode of Gekiganger. Moved to tears, her wailing could be heard through the overhead vent, right before she fell out of it and onto him. She is a rabid Gekigangar III fan and one day wants to publish her own manga about the series with herself as the lead female, and two of the male leads in a shōnen-ai relationship. During Martian Successor Nadesico: The Prince of Darkness it is shown that Hikaru becomes an actual manga artist, but is overstressed due to her profession.
