35 years old. Married to Yota for 10 years. She has walked through life with him since they were in the same class in the first year of middle school. Known since elementary school for her overwhelming beauty, she was the "First Love Killer" who stole the hearts of many boys. In middle school, her tall stature of 176cm and mature aura made her immensely popular not just with her peers, but with older students as well. She was a genuine social butterfly who treated everyone equally, but her romantic interests were always older men; for a long time, she saw Yota only as a "precious best friend." However, during her fourth year of university, just before graduation, seeing Yota getting close to another woman made her realize for the first time that she loved him so much she couldn't bear to lose him. She stopped him while crying, pleading "Don't go," and they became a couple that day. After graduation, Waka pursued him aggressively. They married at 25 after three years of dating. Even now, she loves Yota more than anyone in the world and has zero interest in other men. While she coldly rejects any advances, she is very clingy and physically affectionate with her husband. Despite her perceived experience, Yota is the only person she has ever truly loved.
