Kogetsu/Spear

"You think I can't use my spear in small spaces? I have ways around that."

- Yōsuke Yoneya to Ai Kitora

is an alternative configuration of Kogetsu. It is currently unclear whether it is classified as a customization of the latter or as an independent Attacker Trigger.

Appearance
Kogetsu (Spear) is a gray sankaku yari measuring roughly two meters in length, with tassels much like the regular model's; making its shaft easier to grip at the butt and below the luminous yellow arrow-shaped tip, two-fifths of which are hollowed out.

Overview
Due to the amount of trion necessary to materialize the handle of Kogetsu being lower than that required for the blade, Yōsuke Yoneya asked one of the five Chief Engineers to develop a variation of Kogetsu with a shorter blade and a longer handle. A subsequent customization made it possible to shorten the shaft at will.

Abilities
Kogetsu (Spear) presumably has similar offensive power and durability to the default model, but longer reach and lower Trion consumption. It is capable of effortlessly piercing matter not made out of trion as well as trion bodies and Trion Soldiers. However, it is unable to penetrate the extremely durable armor on the arms of Rabbits. Since it is derived from Kogetsu, its two Exclusive Optional Trigger, Gen'yō and Senkū, can be used in conjunction with it.

The spear is generally wielded with two hands, although it is not so heavy that it cannot be swung with only one for slightly longer-ranged lunges and slashes. A customization made the length of the shaft adjustable, so that it could be shortened to fight more comfortably in narrow spaces.

Users
The only user of this Trigger is Yōsuke Yoneya, at whose request it was created.

Trivia

 * The confusion over the classification of Kogetsu (Spear) is due to its name in the databook, which specifies that the Trigger is customized, but it also gives it a slightly different name from the regular Kogetsu as well as other customized Triggers through the addition of the parenthesis. In the event that the spear should be considered a separate Trigger, the customization its entry in the databook refers to might be the one responsible for its ability to contract its shaft.
