Fūjin

"Usually, only someone compatible with a black trigger can use it. But Jin's Black Trigger... Wasn't particularly picky."

- Shiori Usami

The  is a Black Trigger created by Sōichi Mogami.

Appearance
The Fūjin's overall appearance unactivated is a long, blackish sword handle with green circular designs on the bottom half of the handle and a green line in the middle of those designs. When activated, it releases a greenish white blade, becoming similar in appearance to a Kogetsu trigger.

Abilities
It is a specialized offensive trigger that can sprout up to 11 ribbon-like "blades" of wavy light (in addition to the main blade) and attack opponents with them. The ribbons are not solid blades that can be used when swinging Fūjin but act as indicators of how many ranged slashes are left to be used. The blades 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 eleven are used, the user has to "recharge" them before using them again, which could give opponents an opening to attack the user. However, when combined with Jin's ability to see the future, this weakness can be countered. Fujin main blade can also be use to fight at close combat though Its main blade attack does not seem to be more powerful than those of other attack type triggers.

Another possible weakness of this Black Trigger is that it is no different from normal triggers when its user does not use its special ability to transmit slashes. Its main blade attack does not seem to be more powerful than those of other attack-type triggers. However, since the slashes are transmitted through surfaces, such as walls and the ground, being in an enclosed space with a Fūjin user may create hazards for the attacker, as the slashes can be transmitted to strike opponents from odd angles in that situation.

In open spaces, the remote slashes give Fūjin the obvious advantage of range against other attack-type triggers.

B-Class Rank Battles Arc

It will be available to all of the compatible candidates for use on an as needed basis. All candidates will be trained to use Fūjin with Yūichi Jin as their instructor.
