Ruka Kanae is a key character introduced in the Achiga-hen (Side-A) arc of Ritz Kobayashi’s Saki franchise. She serves as the captain of the mahjong team, a prestigious powerhouse school. At first glance, Ruka fits the "Yamato Nadeshiko" archetype: she is soft-spoken, elegant, polite, and moves with a serene grace. Her long, jet-black hair and traditionalist mannerisms paint the picture of a quiet bookworm.
