Kogetsu/Gen'yō

"So the tip changes shape. That's why it kept getting me when I thought I dodged."

- Yūma Kuga

Gen'yō is an Optional Trigger exclusive to Kogetsu, both the regular one and its Spear variant. An attack carried out using this Trigger takes the name of Gen'yō Kogetsu.

Appearance
Gen'yō allows the user to modify Kogetsu's blade as they see fit. As such, it has no fixed shape.

Overview
The origins of this Trigger are unknown.

Abilities
Gen'yō allows the user to freely manipulate the shape of Kogetsu's blade. It is primarily used to foil the attempts of the opponent to counter an attack, sprouting additional blades if they try to dodge, changing the shape of the blade if they interpose a defense in order to bypass it.

Gen'yō is particularly useful against those Triggers with which contact must be avoided, like Nikokyra, as the user can bend the blade not to touch it and restore its original form immediately afterwards, effectively circumventing the obstacle. It is generally unable to inflict lethal damage on a watchful foe, but it is very effective when targeting limbs. Particularly quick users can activate Gen'yō only after starting the swing and switch it off as soon as it is over, thus preventing the opponent from understanding why they have been hit.

Users
