Jin is a fair skinned teenage boy and he strongly resembles Shoichi. Like Shoichi he has grey eyes and purple hair, but his hair is long and unkempt, reaching past his shoulder and it is lighter shade than his brother. He is depicted wearing a dull-colored shirt with sleeves ending halfway down his elbows and pants. As a child, he had short hair and wore a short-sleeved, light blue shirt and a pair of khaki shorts.
According to Yusaku after being rescued from Hanoi Project Jin developed intense PTSD and even now he is still suffering from PTSD. Since the events of the Lost Incident he has become withdrawn, reserved and closed of his heart from the world. As a child based on the picture of him and prior to getting kidnapped for Hanoi Project he appeared to be cheerful and outgoing.
Both Jin and Yusaku were victims in the Hanoi Project 10 years ago. Despite having been rescued, he is still suffering from the shock of the incident. This event drove Yusaku to fight for him, and defeat the Knights of Hanoi so that Yusaku might save him from darkness.
Jin has been mentioned several times by Yusaku Fujiki and Shoichi Kusanagi during their fight against Hanoi. After Shoichi discovered the true identity of Blue Angel who is Yusaku's classmate and step sister of SOL Technologies Security Manager Akira Zaizen Shoichi suggests Yusaku to meet her so that he can get a lead on Akira regarding Jin as well as Yusaku's stolen memories but he doubted the plan would work due to Yusaku's poor social skills with women.
He was indirectly mentioned during Playmaker's duel against Varis as the former vowed to Varis that he would save him. While Yusaku and Shoichi were deleting the files of Playmaker that people post on the network, Yusaku wondered if it was wise to seek Varis out for answers about Yusaku's past and about Jin.
When Shoichi was writing his report, he also wrote that he still thought of his brother, Jin, and wished that the reader of this report would tell that to his brother when they meet him. During Playmaker's duel against Varis, Shoichi hoped that Playmaker will win against Varis so that he can tell the truth to Jin.
