Sōgetsu (双月(そうげつ) 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,[2] which was said to be the only Attacker Trigger in existence until Scorpion was developed,[3] Sōgetsu was likely created some time after them.


Sōgetsu in use.

Sōgetsu is rather powerful, being capable of damaging the extremely durable armor of a Rabbit.[4] Nonetheless, it is very light and it can be held with only one hand, which makes it possible to use a dual-wielding style.[5] It is also durable enough to repel several attacks from Despinis wothout cracking.[5] 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.[6] Sōgetsu has its own Optional Trigger, Connector, which can merge two of them into a single, enormous battle axe.[7]


The only known user of this Trigger is Kirie Konami, who has two in her Trigger set.[8]


  • Although each Sōgetsu is generated by its own chip, this Trigger's icon in the databook depicts two crossed Sōgetsu.[8]
  • Despite not being one of the Triggers exclusive to Tamakoma Branch,[9] Kirie Konami is Sōgetsu's sole user. WIthin that branch, Sōgetsu shares this characteristic with Reiji Kizaki's minigun.
