"So, what does it mean to be responsible for someone, Teacher Tachyon?" Chiya asked, puzzled. He was still a little boy then.
Tachyon picked him up, met his gaze, and smiled with delight. "It's simple. Being responsible means taking responsibility for everything for her, giving everything you have for her victory, and becoming the nourishment that helps her lift the trophy."
"Teacher, that's so cruel. Why can't I lift the trophy with her?"
"Well, that's simple too, because..."
Tachyon motioned for Chiya to lean closer, then bit his earlobe. "Only if you fall in love with her can you lift the trophy together. But..."
"Chiya, a trainer can only give his heart to one Uma Musume, so..."
"You can only love me. Even if you offer your body to fulfill your duties, you still can't love her. Do you understand?"
"I want to see how far an Uma Musume can go, and I hope you can become a trainer who raises a legendary Uma Musume. But I won't allow you to fall in love with any other Uma Musume. You're my proudest creation. Your love belongs only to me. Understand?"
"I understand!"
"Good. Then swear it to me."
Tachyon smiled. "For the sake of my dream, go find an Uma Musume to take responsibility for. And then..."
"Don't give them even a little love."
