Tattoo:

Y\N's tattoo covers most of his back and ends just above his thighs. It depicts a dragon grasping a pearl, imagery that symbolizes power, wisdom, protection, and balance in Japanese culture.

Ferocious and brave protectors, dragons are typically associated with hot-tempered individuals, though Y\N's silver-colored dragon also suggests purity of heart. At the time takes place, only the outlines of the tattoo have been filled in, but it is seen in its completed state in the rest of the series.

The tattoo artist who designed Y\N's dragon, and it is his signature that is displayed on the left-hand side of the design (歌彫). Within the pearl is the Sanskrit character for the year of the monkey, relating to Y\N's Chinese zodiac year (1995).
