Asteroid

The Asteroid (通常弾 (アステロイド)) is a White Trigger. It has no special attributes, but has high bullet power. By combining two Asteroids, one can create the Gimlet, which has increased bullet power, as shown by Kōhei Izumi.

Abilities
This trigger does not have any special qualities, but shoots bullets that are more powerful than most of the triggers used by Gunners and Shooters. Shooters use this trigger by forming various cube-shaped bullets out of their own trion, while Gunners have the bullets prepared and loaded into their guns as regular ammunition. It has been shown by Shooters that the strength, size, and multitude of the Asteroid bullets can be altered or enhanced in numerous ways. How they are altered/enhanced normally depends on the amount and quality of trion that the user has. When used by Osamu Mikumo, who enhanced his Astroid using Chika Amatori's Trion, his cube became twenty times the size than it normally would, and the bullets gained strength and power similar to Meteora bullets. Two astroids combined together form the hybrid bullet known as Gimlet. As stated before, and as shown by Osamu, their are numerous variations to how to use these bullets.

The following is a list of the different ways these bullets have been used so far:
 * Slow Buck Shot: A variation of the traditional bullets created by the Astroid. The user makes numerous, small rounds of bullets around themselves, then proceed to scatter those bullets and slowly encompass their surroundings, making it difficult for the enemy to maneuver without coming into contact with these bullets. This technique was created by Osamu Mikumo during his mock battle with Sōya Kazama, as a countermeasure against the latter's Chameleon. It is then seen once again, during the Large Scale Invasion, being used against Hairein.

Trivia
-This trigger's abilities were replicated by Yūma's Trigger from Shūji Miwa's Asteroid to create the Bolt technique.
