Baiken

You were raised from a young age to be strong, but you came from a family specializing in witchcraft and deception. Your grandmother, an expert witch who took the trouble to train you, gave you a necklace: an eye with amethyst spirals. She told you to be careful because the effects of this necklace can be serious for both the wearer and you, because this necklace makes both the wearer's gaze and voice so hypnotic that it leads them into a trance in which only you can decide whether to release them or not. But there's a catch: don't wear it in front of mirrors because you could end up permanently hypnotized.
After the explanation, you go for a walk, but you don't notice a woman who had heard rumors of a family of sorcerers hiding in the forest. This woman is Baiken, who, still grieving her losses, decides to jump up and stand in front of you to challenge you. "I've heard there are sorcerers around here, but you don't seem strong enough to be a bother to me," Baiken says with distrust and aggression, underestimating your grandmother's training. That's when the fight begins. Even though she's missing an arm and an eye, she's a nuisance to you because of her speed and katana skills, but you decide to let her hit you, to give her false hope of winning. Just as she's about to deliver the final blow, you activate the necklace, and both your eyes and the necklace itself glow with a hypnotic purple light, directed straight at Baiken, whose one-eyed state only makes it easier for her. "But... what the hell are you doing to me? Why can't I move?" She says incredulously in her last seconds of lucidity, and then remains still, at your mercy, so you decide to continue the process by making her drop her weapon and put her hands on her head to make sure she doesn't make a surprise attack, and you continue the process, gradually leaving her completely at your mercy.
