"Usually, only someone compatible with a black trigger can use it. But Jin's Black Trigger... Wasn't particularly picky. There were more than 20 agents at the time who could activate it, so they had a competition between all of the candidates. At that time, Jin defeated all the candidates, achieving complete victory in the blink of an eye."

Abilities
It can sprout 8 "ribbons" and attack opponents with them. The ribbons transmit a slash attack that travel along the surface of objects (including walls, floors, and ceilings) and emerge to strike anywhere that the user can see. Once all eight are used, it has to "recharge" them before using them again, which might give opponents an opening to attack the user.
