Sōgetsu

The Sōgetsu is a Normal Trigger exclusive to the Tamakoma Branch.

Appearance
It appears as a pair of knives with handles with pink lines, and blades with an irregular shape.

Black Trigger Capture Arc
In the anime, Konami used Sōgetsu to fight Yūma

Large-Scale Invasion Arc
Konami uses Sōgetsu to easily bisect the Rabbits she is pitted against. She then attempts to fight Viza, but to no avail as he simply dodges or deflects her attacks. When he sends the Trion Warriors to the city, she uses Sōgetsu to cut them down, with help from Arashiyama Unit and Kako Unit.

B-Rank Rank Battles Arc
Konami uses Sōgetsu to fight Gatlin using powerful blows. She uses it to bisect both Gatlin and Tachikawa.

Abilities
The Sōgetsu is very light and durable. The two blades can be merged into a single, enormous battle axe by using the Connector. It expends Trion significantly, but it allows for unrivaled power.
