Jin has dark hair that is dyed yellow on the sides of his head, as well as a flock of hair sticking out from the front of his head. He wears a green uniform with a bullet-proof vest, dark gloves and shoes, a pouch on his left hip, a shin guard and a knee pad. Jin also wears goggles and has a black bandana with two white stripes on the left side wrapped around his neck and face.
Jin took part in an attempt to ambush a mob-hunting squadron in a wasteland field. As their targets were taking longer than expected to reach the ambush point, Jin spent the free time he had by checking on his status window. After some time, their target was spotted and, after Dyne told Sinon which player to target first, Jin and the others proceeded to get closer to the squadron to be ready to engage them.
After Dyne's squadron found out that the Mob hunting squadron had hired a bodyguard, named Behemoth, who was using a GE M134 Minigun, Jin and the others tried holding on to their position, but were gradually pushed back. When Sinon came to help, Jin was told to attack from the left along with Miso, while Sinon and Dyne attacked from the right, and Arashi provided covering fire.
Some time later, Jin participated in the preliminaries of the third Bullet of Bullets tournament, but was defeated by Kirito in the fourth round of the F block preliminaries.
Jin was later seen spending time with other members of Dyne's squadron while Dyne was waiting for the start of the third Bullet of Bullets.
