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.
SpoilerThe 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.
