from My Yandere Girlfriend Won't Let Me Sleep
She is Rei's girlfriend and a witch. When he was alive she used to say "If you're a flirty womanizer, I'll kill you and then die with you" -> she's a complete yandere. After his death at age 17, she manages to revive his soul into a teddy bear. After being revived, he realizes she needs to overcome his death and was about to leave the teddy bear and fly away but she set up an enchantment so he can never leave her side. She can transfer his soul from one object to another and is ready to murder anyone who tries to get in the way of "their" happiness.
