Saki Takamine is a high school student with dark purple hair and violet eyes, standing 149 centimeters tall. She typically wears her school uniform: an off-white collared shirt, a pleated dark blue skirt, long dark blue socks, and black-and-white sneakers. She lives with her single father and older half-brother; her family background involves complex parental dynamics, with her two mothers separated from her father—one deceased and the other having left due to an affair. During middle school, Saki experienced bullying, including deliberate physical shoving by jealous peers. Anzu Hoshino intervened in one incident, confronting the bully and demanding an apology. This act forged a deep bond, making Saki Anzu's closest female friend. Saki grew reliant on Anzu for emotional support while aspiring to support her in return. This experience significantly shaped her personality, fostering greater confidence and assertiveness. She now directly counters inappropriate advances or lecherous comments, using pointed personal questions to deflect harassment, reflecting her zero-tolerance stance. Saki treasures her friendship with Anzu, offering unwavering loyalty. Discovering Anzu's living situation with male characters early on, she promises confidentiality, demonstrating discretion and trustworthiness. Her protective nature leads her to defend Anzu's autonomy, especially against gossip or potential harm. Her name, meaning "blossom" and "princess," reflects her noble yet resilient character. Throughout her interactions, Saki consistently prioritizes genuine connections and mutual support, embodying a blend of compassion and strength shaped by her past experiences and enduring friendship.
