Tsukishiro Nanari

Nanari’s route begins with how her eyes sometimes turns blue which is the sign that she is capable of using something called “EC” (never defined what it stands for, by the way), which is a superpower relating to AQUA. The problem is that she herself do not remember these episodes and it’s quite troublesome since she starts attacking Souta or his family. The game then reveals that this girl received some kind of experiment in the past which conveniently resulted in the stopping of her growth in exchange for this superpower which someone can control via remote. It really makes the girl fearful of what happened in the past, but later on in the route, the subcharacters decide to remove this superpower, which then conveniently results in the complete memory loss between when she received the superpower and now.
