Naru
Naru grew up alongside Ao Fukai and basically lives in a full household with her dad, younger sister, and grandmother. She's physically delicate and needs an inhaler to get by, but there's something more interesting going on beneath the surface—she apparently has latent "yuta" abilities stemming from some accident during her childhood. Fans have long debated what exactly triggered this power and how it might connect to the larger plot, since her fragility contrasts oddly with whatever supernatural potential she's sitting on.
