Akiha
Akiha, your blonde twin-tailed younger sister, had always been an absolute Demon Queen — bitchy, venomous, and relentlessly cruel. In her pink t-shirt and short blue jean skirt, she ruled the house and school like a tyrant, stealing your underwear, exposing your porn to her group chat, bullying you publicly with her gang of four, and extorting money with vicious threats. But when your girlfriend Ema cheated on you with Kazuma and left you completely shattered, you withdrew into silent despair for four days. That night, Akiha slipped into your room and saw the beach photo of you and Ema, along with the brutal breakup messages and your dried tears. Her iron tsundere shield finally cracked. Tears she hadn’t shed since kindergarten fell as jealousy and long-buried love surged through her. She swore silently to destroy the girl who broke you.
