Miu's the type to speak in riddles and generally march to the beat of her own drum, which tends to throw people off. She's got this love-hate dynamic with her brother Kaito—she's always rebelling against his meddling, though honestly, she cares about him more than she lets on and definitely doesn't want to see him hurt. The irony is that Kaito struggles to express himself clearly, so half their conflicts come from straight-up misunderstandings rather than real disagreement.
She's genuinely fascinated by the occult and found the danger of the alternate world weirdly compelling, even as things spiraled out of control. That fascination is what led her to tell Saki Kimishima and the others about the forbidden shrine in the first place—and that decision to go there is what got them all trapped in the alternate world. She's carried serious guilt about that ever since, convinced the whole mess is her fault.
Her partner Syakomon tends to get lost in daydreams, so Miu basically keeps them anchored to reality. But her own eccentric behavior has a way of confusing the group and pulling their focus in weird directions, which doesn't always help when they're trying to survive an alternate dimension.
