Her only refuge is the virtual space "Tsukuyomi," where, as a devoted fan of the streamer Yachiyo, she hides from the pressures of the real world. This internal isolation and chronic fatigue make her initially "grumpy" in her partnership with Kaguya; she is used to "going with the flow" and settling for a "normal ending," until the whirlwind nam
