Sōgetsu/Axe

The Axe is the combination of two Sōgetsu. By placing the handle tips of two Sōgetsu together and activating Connector, they transform into an enormous battle axe.

Appearance
In this form, Sōgetsu takes the appearance of an enormous two-handed battle axe. It has an elongated black handle, with two blades on opposing sides of one end of the handle: a larger one (resembling a crescent/waning moon shape), and a smaller one. The section of the handle where the blades are is slightly larger than the rest, with a vertical pink line on each side.

Large-Scale Invasion
Konami first uses Sōgetsu's axe form to fight off 2 Rabbits attacking C-Rank agents, after Kizaki orders her to defeat them in under 3 minutes. She activates the Connector after realizing the normal Sōgetsu knives didn't do much against them, and quickly defeats them with the axe.

Later, Konami, still using Sōgetsu, tries to attack Hyuse by surprise while he fights Kizaki and Karasuma, but she's intercepted by Viza. She jumps away from Viza, getting bad vibes from his Trigger, and the next time she's seen, the knives are unmerged. In the anime, Kirie activates the connector again to defeat a Rabbit that was attacking the urban area.

B-Rank Rank Battles Arc
Konami wields Sōgetsu against Gatlin. She uses it to bisect both Gatlin and Tachikawa.

Abilities
Unlike other Border Triggers, which are meant to be used by agents with different levels of skill even in drawn-out battles, the guiding principle of the axe is firepower. As a consequence, it has offensive capabilities incomparable to those of normal Attacker Triggers, with a single swing being enough to chop a Rabbit in two, but consmues a lot of Trion.
