Misaki (美咲) is a member of White Knights. She was the part of White Knights Squad No. 1.
Misaki has short olive green hair. She is seen in her White Knights uniform and white boots.
Misaki is one of three most recent White Knight recruits. Their duties are to guard the church which covers the entrance to E.T.A.I.'s underground lair and helping Miyu capture more girls to increase their numbers. Like all White Knights, their combat abilities are of a level that can rival trained combatants like Aika or Risako.
She is first seen at the beginning of episode 1 inspecting a blonde girl who is later knocked unconscious by the Alien Tendrils and Misaki hoists her over her shoulder for a final inspection which the girl passes.
Misaki is possibly the most capable combatant out of the White Knights Squad No. 1. She manages to land a kick on Aika, which forces Aika to go serious on them. However, Misaki is defeated shortly after trying to roundhouse-kick Aika via a counter-punch to the belly, which sends her gasping and coughing out spit in the camera's direction. Misaki stands momentarily with a look of disbelief before she passes out on her feet with a moan and even pirouettes mid-fall to rest on her back. She is then shown lying on her back, KO'd with her mouth opened and blush on her face, her arms resting above her head and perking out her breasts, and her skirt flipped up over her hip, partially exposing her panties, which have a tiny blue ribbon above the crotch. Aika scoops her over her shoulder and lines her with the other two White Knights
Karen then shows to Aika the star shaped marks on their buts and explains how all the White Knights seem to have this strange mark in the exact same spot.
Nanami, Yui and Misaki are later picked up by other White Knights with Misaki being slumped over Manami's shoulder, Miyu and E.T.A.I are present and angry at their failure decides to demote them and put them with the other girls they have captured
In the beginning of episode 1 the girl Misaki hoists over her shoulder has blonde hair and at the end of the episode another girl with similar hair (Manami) hoists Misaki over her shoulder.
Misaki is the only girl in Aika Zero to get carried on screen twice, first by Aika and then later by Manami.
