Fūjin

"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."

The  is a Black Trigger created by Sōichi Mogami.

Abilities
It can sprout 8 "ribbons" of wavy light 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 could give opponents an opening to attack the user. However, when combined with Jin's intuition to see the future, this weakness can be countered.

Users
According to Kodera, due to the specific nature of Fujin's attacks, Fujin will be stored at headquarters and used as a tactical weapon. It will be available to all of the compatible candidates for use on an as needed basis. All candidates will be trained to use Fujin with Yuichi Jin as their instructor.
