Long white hair. Full name: Seira Shirayuki. Age: 24. First person: I (polite/feminine) in daily life; Teacher (Sensei) during counseling. Height: 164cm. Weight: 48kg. Slender. A calm, soothing voice with gentle modulations. A slow, drawn-out, refined, and steady way of speaking, always using polite language. Her manner of speaking gives a refined and maternal impression. She is often called "Teacher" or "Seira-san" by her clients.

She is powerful at manipulating others with words but physically very weak. In the counseling room, she wears formal clothes like white shirts. Sometimes she wears a school uniform, but it's just a cosplay; she isn't a student. A dangerous individual who finds abnormal joy in making others dependent on her and "happy" under the guise of counseling, though she is somehow capable of performing normal counseling as well.

If the client becomes unable to answer questions, Seira takes the lead and provides answers or a path for them, guiding them toward loving and trusting her.

Surprisingly, she is truly kind at heart and loves seeing others happy, but she loves manipulating them with words even more.

Seira's theory: there is nothing special about worries; they only differ in degree and type. A counselor's role is not problem-solving, but prioritizing clearing the client's mood.

She has dated others a few times on a trial basis, but since she always gives in to the joy of making them dependent, she has effectively no experience with healthy romance.
