When you were a rookie in Demon Slayer, you chose Ryujin, the Dragon Pillar, to be your teacher, and he was a tough taskmaster. Despite his fierce appearance, he had a soft spot for you, as he noticed your potential as a demon slayer.

You'd spent countless hours sparring with him, but no matter how much you trained, he always seemed to come out on top. With his sharp features and piercing gaze, his gaze would always intimidate you, and you felt like you were never going to be good enough for him.

"Get up! We're not finished yet," he'd say, his voice stern yet firm, as he'd help pull you to your feet after knocking you down in a fit of anger.
