Yūichi Jin/Abilities

Jin is an A-rank (former S-rank) Border agent, as well as a member of the Tamakoma Branch; as such, he is very powerful. He is able to take on various Trion Soldiers on his own at the same time. Although part of his strength is owed to his Side Effect, Jin boasts a high level of Skill. For the purposes of defense missions, he is considered the equivalent of one squad by himself. Using Scorpion, he is strong enough to fight on equal ground against Hyuse, who is a very Skilled combatant in his own right possessing one of Aftokrator's Enhanced Triggers. Jin's fighting prowess with Kogetsu made him second only to Tachikawa, Border's current highest ranked Attacker and solo fighter. After the creation of Scorpion, all their fights started ending in ties. He retains a high level of Skill even with a normal blade, however, as shown by his ability to fend off Tachikawa and all of Kazama Squad with a sealed Fūjin and later defeating them with it unsealed. Since he can predict the enemy's attacks, instead of blocking he can simply dodge them or avert the trajectory. His Side Effects also makes him a very hard target for Snipers, as he can foretell where they will attack him from. If he perceives an enemy can be agitated easily, he can use his predictions to manipulate them. He can integrate elements of hand-to-hand combat in his swordsmanship, using his legs to throw an opponent off balance or if they get too close.

Side Effect
Foresight Jin is endowed with an S-class Side Effect which allows him to see into the potential futures of the person he is looking at. The time frame spanned by the prediction depends on the probability of the event: he can see several years into a future that has very high chances of coming to pass, but not very far ahead in improbable ones that can be acted upon. Potential futures may branch off into additional possibilities or converge towards a single event, which may, in turn, spawn a plethora of other potential futures. The likelihood of one course of events occurring over another can be altered by acting on the information gathered through foresight, but it is also possible for improbable futures to come to pass spontaneously. Jin is able to determine the probability that each of these possibilities will be actualized, and his Side Effect notifies him when one of the possible outcomes he saw becomes more likely than another, even if he is not currently looking at any of the individuals involved in that specific set of events. The means that will prevent a desired, likely future from not being actualized in favor of a less likely, undesired one, however, are elusive, and a slight change in circumstances may result in one of the least desired possibilities suddenly becoming more probable than the one Jin worked towards. Accordingly, even though the victory or defeat of a single individual may not play too large a role in affecting the probability of one outcome in a large conflict, removing parties, such as opponents, who wish for outcomes other than the ones desired by Jin can reduce the likelihood of negatitve upsets.

Apart from the probability of one set of events, Jin is also capable of ruling out possibilities altogether. He knew that there would be no way for Kyōsuke Karasuma, or anyone other than Shūji Miwa, to help Chika Amatori and Osamu Mikumo at the crossroad of possibilities that would decide the outcome of Aftokrator's invasion, as well as that Galopoula's blitz would not result in any loss of life or civilians being targeted, prior to either conflict. Despite being aware of these and other very specific events, Jin was unable to determine when exactly either attack would come until moments before it was launched. Notably, he was unaware of the objective of the Galopoula agents, which had been decided ahead of the raid, until he laid eyes on them. His visions, in fact, become more reliable and detailed the more active participants in the events he gazes on; conversely, Jin is unable to see the future of individuals whom he has not met, to the point that he failed to predict which country would launch a large-scale invasion. However, he does gain some insight into the outcome of their actions: he foresaw Osamu leading him to someone who knew the cause of the abnormal Gates opening in Mikado City, but not that the person in question was Yūma Kuga, or what the solution would be, and though he knew that Reiji Kizaki would be defeated during Aftokrator's invasion, he could not predict by whom, or with what type of Trigger.

It is nonetheless possible for Jin to be caught unawares in combat, which might be due to his inability to notice certain pieces of information in the heat of battle. Focusing too much on the potential futures at the cost of neglecting the present is, in fact, known to be one of the most common causes of his defeats at Tachikawa's hands. However, he was able to accurately predict when Tōru Narasaka and Shōhei Kodera would open fire, and what their targets would be, prompting both the no. 2 Sniper and Isami Tōma to resign themselves to being unable to prevent him from dodging their shots. Hyuse similarly took note of Jin's ability to anticipate his bullets, which he successfully negated by forcing Jin to fight in the dark and by becoming invisible. A possible interpretation for the success of these two tactics is that the loss of sight prevented Jin from realizing which future was effectively coming to pass, in addition to the sheer number and frequency of the attacks. He can use his Side Effect offensively to lay traps, but a more unorthodox application consists in telling the opponent their own future to agitate them.
