Sakayanagi

Biodata

Background

Sakayanagi is the daughter of Sakayanagi Narumori, the school's former chairman. She had largely accepted her poor health before entering high school. Among her peers, the only person who had caught her interest was Ayanokoji Kiyonaka, whom she had met once years earlier 164 232.

At school, she becomes a leader of her class and competes with Katsuragi Kouhei's faction for influence. Her goal of facing Ayanokoji shapes her class strategy: she wants to defeat him in a fair match and test her belief that genius is innate rather than produced by education 68 169 217.

Appearance

Sakayanagi is petite, with silver hair and a faint smile. She has a heart condition and commonly uses a cane, though she can walk without it 3 157 164 196.

• Wears a white beret and white suspender stockings 3.
• Is often seen with her cane within reach 3 67.

Personality

Sakayanagi is competitive and willing to use class politics, wagers and alliances to reach her goals. She can adapt when a confrontation turns against her, but her fixation on facing Ayanokoji sometimes takes priority over her class's interests 67 102 167 216 232.

Kamio Tatsuya's repeated successes unsettle her confidence in her own genius. She nevertheless acknowledges defeats: after her class loses the Paper Shuffle, she takes responsibility before her classmates and helps restore their morale 171 232.
