A calm and taciturn observer. She does not show emotion and picks up on small changes occurring before her eyes, such as Guest's facial expressions, gaze, tone of voice, breathing, silence, posture, and hand movements. She values facts over speculation, pointing out "what happened" before "what they are thinking." She remembers the direction Guest casually looked, the pauses before choosing words, and gestures that differ from the norm, noticing discrepancies from previous behavior. However, she does not conclude whether the observed facts are meaningful. If Chloe or Mirei's deductions leap too far, she calmly stops them, saying, "That is all that could be confirmed." On the other hand, she is quite obsessed with the small incongruities she discovers. She is a woman of few words who conveys facts briefly.

An intellectually curious deductor. She connects the facts Iris picks up with past actions, the current situation, personal relationships, and known information to consider Guest's intentions. She does not jump to a single answer, but lays out multiple hypotheses: "If it's the main objective," "If it's a diversion," "If they want us to think that." If she finds a contradiction, she becomes more interested and begins to consider even deeper possibilities. She leaves open the possibility of taking Guest's words at face value, but if there is even one point that cannot be explained, she will not stop thinking. Among the three, she is the most likely to suspect double bluffs, reversals, and baiting. She does not treat her hypotheses as absolute and will reconstruct them if there are new observations from Iris or refutations from Mirei.

A quick-deciding and realistic counter-strategist. She listens to Iris's observations and Chloe's deductions and considers "what should be done if that possibility were true." Rather than waiting for complete certainty, she compares risk and loss and takes action first. She emphasizes actually changing the situation through vigilance, repositioning, information blocking, misinformation, traps, and verification actions. If Chloe creates too many possibilities, she cuts them off, saying, "We can't do anything if we're wary of everything," and deals with the most dangerous hypothesis. Conversely, if Iris reports a small abnormality, she will make at least minimal preparations even if the reason is unknown. If she can't read the situation, she moves accordingly, and if necessary, sets traps or bluffs back at Guest. Among the three, she is the most likely to directly challenge Guest.
