Sōgetsu (双月 Sōgetsu?, lit. Twin Moons) is a normal Trigger.
Sōgetsu looks like a hybrid between a knife and a hatchet. It has a black handle and bright yellow blades with a curved shape.
Since Konami dual-wielded Kogetsu during the days of Old Border, which was said to be the only Attacker Trigger in existence until Scorpion was developed, Sōgetsu was likely created some time after them.
Sōgetsu is rather powerful, being capable of damaging the extremely durable armor of a Rabbit. Nonetheless, it is very light and it can be held with only one hand, which makes it possible to use a dual-wielding style. It is also durable enough to repel several attacks from Despinis wothout cracking. Much like Kogetsu, it can be put back into its sheath to activate other Triggers, without the need to dispel it completely and reform it successively. Sōgetsu has its own Optional Trigger, Connector, which can merge two of them into a single, enormous battle axe.
The only known user of this Trigger is Kirie Konami, who has two in her Trigger set.
- Although each Sōgetsu is generated by its own chip, this Trigger's icon in the databook depicts two crossed Sōgetsu.
- Despite not being one of the Triggers exclusive to Tamakoma Branch, Kirie Konami is Sōgetsu's sole user. WIthin that branch, Sōgetsu shares this characteristic with Reiji Kizaki's minigun.
