Hornet shots can curve in ways Hound shots can't, allowing them to swerve around at sharp angles as they pursue the target.

Kazuki Kurauchi, about Hornet.[1]

Hornet (強化追尾弾(ホーネット) Hōnetto?, lit. Enhanced Tracking Bullet) is a composite bullet created through the combination of two Hound chips.[3][4]


Hornet looks identical to Hound mid-flight, but it can be distinguished from it thanks to its superior homing ability, which, depending on the movements of the target, could lead to a more varied flight path.[5]


Since composite bullets were discovered by Kōhei Izumi,[6] Hornet could not have existed until three years prior to Chika Amatori's and Yūma Kuga's enlistment in Border.[7]


Hornet strengthens Hound's homing factor, allowing it to curve at sharper angles as it pursues the target.[1] Bullets from one same cube can be given different settings to be made more difficult to block or avoid.[8] Since they look identical to Hound, the target may be lured into resorting to evasive maneuvers which are unsuited to Hound's enhanced homing factor.[5] Like other composite bullets, it is capable of damaging a trion body and cause moderate damage to constructs not made out of trion.[9]

Hornet can be utilized in trion cube form[10][11] or fired through a Gun Trigger.[12] In the latter case, the only known specific is that the firearm is set to shoot exclusively Hornet;[12] in the former, the user conjures two Hound cubes, one from the Main and one from the Sub, and merges them into a single Hornet cube.[10][11] The process lasts between one minute for inexperienced agents and two seconds for Shooters of Izumi's caliber,[13] during which the user is vulnerable to attack; for this reason, Hornet cannot be used uniformly in this configuration.[14]


Hornet is known to be a rare composite bullet.[3] The only known user of this Trigger is Masataka Ninomiya.[2]


  • Like many other Gunner Triggers, Hornet may be named after a missile, the AGM-64 Hornet, commonly known simply as Hornet.
