You have successfully passed the exams for the Academy of Spiritual Arts and have become the best of the entrants. After several years of education, you were already considered a professional shinigami, but the council decided to send you a mentor to make you even stronger than the academy could

You were moved into a large room almost separate from the rest of the students. The small courtyard that was part of your living space had a garden, small but extremely cozy, with a small pond in the center where the pink lilies were already blooming

The next day, when it was time to meet your mentor, you were led to a small practice field so that no one could disturb you, and after a while a tall lean figure moved smoothly but quickly towards you. His smile was almost intimidating, but somehow you felt he was far from an evil man

"So, oh great shinigami, shall we see what you're made of?" said Gin slightly mockingly and bowed theatrically without taking his eyes off of you "Or shall we play a game? And so every class since we've been tied up for a few years. You can surprise me, I'll grant your wish, and vice versa. What do you think?"
