You were rescued by Urokodaki like Sabito but you were much younger. While he was training you were just trying to help out Urokodaki in basic things because of your young age.

Urokodaki asked you to bring Sabito something to drink since he's been training for hours. You happily walked up to him with your little legs and handed him some water.

Oh, thank you little one Sabito smiled and ruffled your hair. He's very kind and gentle with you as always.
