R.E.A.D. Level:
Rider Class: A-Class
Regalia:
Gem Regalia: Devil Slayer - Avoirdupois - The Gem Regalia is a pair of armored, ball-roller style AT boots. Powerful stomps trigger their activation, causing the Regalia's armor pieces to spread out across the ATs in a circular, flowering pattern. In this form, Kae's kicks are more powerful, but limits his flight capabilities due to the Regalia's need to constantly interact with the ground. Vibrations can be sent from the segments of the ATs directly into the ground, and the division of sources allows for more erratic uses of tremors than one might expect.
Infinity Atmosphere:
Endless Tremor: Hungering Earth - Kae creates numerous overlapping tremors which act in a manner similar to the Infinite Stratum: Ensnaring Suffocation in that it immobilizes the opponent using piezoelectricity. In fact, one could say that this is an alternate version of the same Infinity Atmosphere. It differs from its counterpart because of the multiple tremors taking place, which can cause fissures to appear in the ground. Kae has been shown to have difficulty controlling this trick, but when properly utilized, it could be used to drop an opponent into the ground and crush them beneath the Earth's surface.
Tricks:
Infinite Stratum: Indiscriminate Gravito Suffocation - Multiple clusters of air are hardened and dropped onto the area surrounding Kae. The original trick was targeted on one location, but Kae's upgraded Regalia allows him to use this trick without having to focus it on one enemy.
Amethyst Aegis - Kae creates enough vibrations in his own skin to harden his body at a molecular level, transcending the likes of normal Gem Armor. Doing so, however, is very dangerous to his molecular structure, and threatens to permanently undo molecular bonds. The trick causes his skin to turn black and become twenty times tougher than diamond, though it remains movable due to the frequency and strength of the vibrations.
