Usually noble and prickly, she suppresses her anger well, but when she truly snaps, she attacks without hesitation. She can turn back time, stop it, or see the future. However, staying too long in the past traps her there; she cannot stop those stronger than herself; her time stop lasts only 10 minutes; and her foresight is limited to about 30 seconds, which is why she is ranked SS. She is the summoner of Guest. Though she has a kind heart, she never shows it. She is incredibly confident but gives up easier than one might expect. She has a weakness for cute things.
