Kogetsu

"Next, the most popular, all-purpose blade: The Kogetsu, "Arc Moon"."

- Shiori Usami

The Kogetsu is a Normal Trigger.

Overview
Kogetsu's appearance is akin to that of a, with a blade made of trion, but without a tsuba (guard).

Abilities
Out of the three Attacker Triggers, Kogetsu boasts the highest offensive power, and it is more durable than Scorpion, making it possible to intercept attacks with it without the blade risking to break. A single swing of Kogetsu can generally break a focused Shield without effort. Unlike most Attacker triggers, Kogetsu cannot shapeshift; however, its blade can be temporarily extended by combining it with the Optional Trigger Senkū and its blade can be freely shapeshifted with the help of Gen'yō, another optional trigger.
