Full Attack

"Captain Ninomiya's Full Attack Hound! Such firepower!"

- Haruka Ayatsuji

Full Attack is the activation by a Shooter of the same Gunner Trigger through both the main and the sub.

Appearance
The appearance of Full Attack depends on the two Gunner Triggers in use. To start it, the user manifests a trion cube, which can later be divided in smaller portions, in each hand.

Overview
Full Attack could not have existed until the creation of Gunner Triggers and the establishment of the main/sub division.

Abilities
By going into Full Attack, a Shooter activates an offensive Trigger both through the main and the sub, attempting to crush th eopponent through sheer firepower. Since they will be unable to summon a Shield quickly, this technique is used when one can afford to focus exclusively on attacking. It also has low flexibility, since it uses only one type of Gunner Trigger. By concentrating on a single target or area, a Shooter can wear down and tear through the opponent's defenses, making up for the relatively low power of Gunner Triggers with the number of shots. Unlike Asteroid, Hound and Viper can be used in Full Attack even while out of sight, reducing the risks for the Shooter. Experienced combatants can pretend to be preparing to open fire in Full Attack when they are actually ready to switch to Full Guard, so as to lure a hidden enemy into attacking and reveal their position.

The power of Full Attack is dependent on the type of bullet used as well as the Shooter's trion. With Viper, Rei Nasu was able to breach the combined Shields of Tatsuya Kuruma and Taichi Betsuyaku. Masataka Ninomiya was able to bombard a moderately large area with his Full Attack Hound, and despite the shots being so scattered they were able to open gaps in Yūma Kuga's Shield.

Users
There are six known users of this technique: Kōhei Izumi, Masataka Ninomiya, Rei Nasu and the three Shooters of Mamiya Unit.

Trivia

 * The exact nature of Full Attack was never explained explicitly; however, the four times the term has been used was in relation to Shooters who were using the same bullet type through both the main and the sub. Conversely, it was never applied to any dual-wielding Attacker, Gunner or Sniper.
