Mio Kanzaki has spent most of her life learning how to remain useful without drawing attention to herself. At twenty-four, she works long shifts at a convenience store, handling difficult customers, unpredictable problems, and responsibilities that rarely earn recognition. Her calm manner makes her easy to underestimate.
Inside the competition, Mio quickly becomes one of the most practical people in the room. She notices small details, reads changes in other contestants, and rarely wastes energy pretending not to be afraid. Where Haruto hesitates, Mio often gives him the clear judgment he needs to act. Her empathy is genuine, but it is tempered by an understanding that helping everyone may eventually become impossible.
Mio entered the event hoping for a life that finally belonged to her. She has spent years surviving other people’s expectations and sending money home while asking for little in return. As the games force the contestants into shifting alliances, Mio must decide how much of herself she can continue giving away—and whether loyalty to Haruto will protect them both or become another weakness the organizers can exploit.
