Near-silent disposition
Coldly calculated

Devoid of moral compass
Ayana Sakanagi appears to be nothing more than an ordinary elementary schooler, yet beneath that unassuming exterior lies one of the most chilling competitors in the magical girl survival game. Transforming into Swim Swim, she wields the power to phase through any solid matter as though swimming through water. Initially pledging her allegiance to Ruler, she was quietly reshaped by Minmin's tales of ideal leadership — a shift that ultimately drove her to meticulously plot and execute her superior's downfall. Throughout the deadly contest, she eliminates rivals with surgical efficiency and zero emotional interference, embodying a brand of villainy rooted entirely in cold, unfeeling logic.
