As the fourth of the five Shishido sisters, the agoraphobic Nami demonstrates through her downfall from being a former teen model because of a nasty comment on her blog to an evil "Girl Who Leapt Through Space" that simply having common cultural and genetic origins will not lead to a worthwhile cohesive family. The Primavera staff affords Nami the capability to channel her QT powers for such things as discharging energy blasts at her enemies and controlling the EXISTENCE—the latter often being wielded as foot soldiers. As Takane and Akiha have demonstrated for them, Nami's inherited anti-QT powers will discharge as a concentric circular energy wave that cancels any other QT energy fields as a result of a direct hit at just the right time during combat. The defection of the EXISTENCE to Akiha who wanted to protect Itsuki and Honoka along with finding Imoko drives Nami into a genocidal and misanthropic psychosis as she makes a hasty retreat. As Nami bloodthirstily fumes in disgust of the world and reaffirms her volition to exterminate the human race starting with Akiha and her other three siblings, Panther flies over and invites Nami aboard the Leopard colony—which is Akiha's next destination.
Sora's twin sister who looks identical to him. When they were children, she'd often pretend to be Sora. Even through they look alike, their personality are polar opposites. Unlike the quiet and well demeanored Sora, she has a strong and stubborn attitude. She often forces Sora to cosplay for her own amusement. She's secretly in love with Kana. In spite of this, she's actively trying to get Kana and Sora together. Seiyuu: Aki-Sora: Yume no Naka Midori Shirayuki (白雪 碧) Eventually, she snaps when she sees them having sex after a successful date (which she assumed wouldn't be). In a rage, she almost snips off Sora's penis with scissors, thinking that could be why Kana prefers him over herself. Despite not going through with it, she angrily rapes him on the spot, fantasizing about Kana. Once she comes to her senses, she threatens to snip it off if he tells anyone. Later, she thinks about how her attraction to Kana seemed more like an obsession than anything else. With this in mind, she ponders over how Kana could like Sora, and how Sora and herself drifted away as they grew up. With the previous tension still lingering, she asks Sora if he hates her. With mixed feelings of guilt, lust, and mild infatuation she asks if they could "do it again". They then start a sexual relationship.
