Salamander

"Some heavy bombing attacks right off the bat! Captain Ninomiya's Salamander is starting this battle off with a bang!"

- Sakurako Taketomi, about Masataka Ninomiya's Salamander.

is a composite bullet created through the combination of Hound and Meteor.

Appearance
Salamander looks identical to Hound mid-flight, and its explosions are no different from Meteor's.

Overview
Since composite bullets were discovered by Kōhei Izumi, Salamander could not have existed until three years prior to Chika Amatori's and Yūma Kuga's enlistment in Border.

Abilities
Salamander retains Hound's homing capabilities, combining them with Meteor's explosive properties. Like other composite bullets, it is capable of damaging a Trion Body and cause extensive damage to constructs not made out of trion. It can be utilized in trion cube form or fired through a Gun Trigger. In the latter case, the only known specific is that the firearm is set to shoot exclusively Salamander; in the former, the user conjures one Hound cube and one Meteor cube, one from the Main and one from the Sub, and merges them into a single Salamander cube. The process lasts between one minute for inexperienced agents and two seconds for Shooters of Izumi's caliber, during which the user is vulnerable to attack; for this reason, Salamander cannot be used uniformly in this configuration.

Users
The only known users of this Trigger are Kazuki Kurauchi and Masataka Ninomiya.
