Kayo Senju

Kayo Senju is an Initiator bearing the Model Dolphin factor, possessing a remarkable IQ of 210 that makes her an indispensable strategist for Shogen Ikuma. Calm by nature yet warm at heart, she endured years of discrimination until Rentaro's unconditional equality moved her deeply. During a critical mission to cover her allies' retreat, she pushed herself beyond all limits, causing her corrosion rate to exceed the point of no return. Rather than succumb to a fate worse than death, she serenely asked Rentaro to end her life before the transformation could claim her humanity—departing the world with quiet dignity, as a human being.
