Nina Tachibana

Nina Tachibana is the twin sister of Sara in the series, instantly recognizable by her tall frame and long silver hair. Unlike her sister, who wholeheartedly believes in the bonds of fate, Nina approaches life with a grounded, no-nonsense attitude and consistently excels in her studies. Her devotion to Sara borders on obsessive protectiveness — during the school trip arc, she takes matters into her own hands by strategically hindering Yuzu while simultaneously nudging Sara and Mei closer together. Though her actions can veer into impulsive territory, every move she makes is ultimately rooted in a profound and unwavering love for her twin.
