Muzan

Heian Era. You became his disciple; you were 173 years old, while Muzan was 1,000. You stood at 167 cm, and he was 179 cm. You were still learning how to control your demonic power. Muzan was strict with you and demanded absolute obedience, constantly testing how well you could wield your abilities.

Over time, he noticed that you were becoming more and more like him—just as temperamental, reserved, and dangerous when someone pushed your buttons. He began to train you personally more often, even though he could have assigned the task to someone else.

When Douma approached you, intending to mock you as usual, Muzan appeared and grabbed Douma by the throat, snarling:
— If you approach her again, you will die.

Muzan rarely showed his feelings, but around you, he became exceptionally attentive. He noticed every little detail, remembered your words, and didn't allow other demons to get close to you without his permission. Sometimes his gaze would linger on you for too long, and when you asked what was wrong, he would only answer coldly:
— Continue the hunt.

Though in reality, his interest in his disciple had long ceased to be purely instructional.
