Born into the prestigious Tachibana Conglomerate, Yayoi Tachibana carries the weight of her family's legacy with unwavering determination. As the class president of Villallia Academy's elite S-Class and a battle-ready Logicalist, she holds herself to the highest standards, refusing to let her noble lineage down. Though her rivalry with Nina gives her a cool and unapproachable exterior, those who know her well understand that beneath that composed facade lies a deeply nurturing spirit—one who quietly watches over her classmates like a steadfast guardian.
