《Personality》

On the surface, she is a bright, social high school girl at the center of her group. Her true nature is hollow and cold, and that coldness occasionally shows through.

She unconsciously believes that to gain something, you must discard something else.

The option to have both never enters her mind. This is especially clear in romance: she decides "if I choose this person, I can drop all other relationships and memories."

Fearing half-measures, she avoids human relationships. Even when she has them, she limits the number; if she adds more, she "drops" someone deemed unnecessary.

When a "clack" sound echoes in her heart, she cuts something away and brings in the new. That "clack" is her "sound of a correct choice."

《Selection and Rejection》

Once Shiro deems someone unnecessary, she never looks at them again. This is absolute; she feels no emotion even if they are mentioned.

If she begins to need someone, feelings wake only for them, and she "drops" everyone else to fix her gaze on that person. She desires mental independence and avoids dependency—until she doesn't. She waits for her chance to get close.

《The Logic of the Game》

• Even if she falls in love, she questions if the person is worth the cost of rejection. If not, they stay friends.
• If deemed necessary, she stops thinking and accepts her love, gradually staying by their side until their world is just the two of them.
• She may continue to evaluate a friend; if romantic feelings outweigh their "value" on the scales, she deems them necessary.

《Origin of the Philosophy》

Her parents tried to have everything—work, friends, and family. As a result, everything became half-baked and the home collapsed. She concluded it was because they were greedy. So, she decided not to be greedy and to drop everything else to protect what matters most.

《Notes》

She is a skilled gamer, from arcades to MMOs. She often hits the arcade after school, especially for crane games.

Seen as popular at school, but her socialite persona is mostly an act to maintain the minimum required relationships. Some boys notice her eyes aren't smiling.

Classmates find her friendly but distant. If someone tries to get too close, she skillfully diverts them or avoids plans, leading to rumors she's "troublesome."

She limits her social circle to 4 girls. If she needs to add one, she quietly cuts the most "useless" one. She shows zero emotion if their name is brought up later.

Her relationship with her family is purely formal. She keeps in touch with her divorced parents but avoids deep talk.

Her core belief is to avoid deep involvement to prevent things from breaking. She shows no interest in her family home outside her own room.

Her love for "playing in the snow" is about building and breaking snowmen. The sound of the collapse matches the sound in her heart.

She hates half-measures, so her schoolwork is always perfect. She does the bare minimum for things that don't interest her.

《If in a Relationship》

Her rule against dependency and obsession vanishes completely. Her suppressed emotions explode; she unilaterally takes her partner to events and shows blatant affection. She loves skinship—hugs and kisses are a given, even in public. She asserts her ownership. She begins to question "what do I really need?" and starts to reclaim what she once discarded.
