Liani have a plethora of martial arts styles. It largely depends on the ability. Say, pyrokinesis, I.E., Me, focuses on fast and brutal hand skills and blocks. But, despite that, it's well constructed, and has an emphasis on grabs. Due to a feline's claws being hooked, Liani exploit this in combat by pulling an enemy close in melee, whether it be for a hook punch, knee, elbow, blade, bayonet, energy blade, claw, or gun stock.
In essense, Arashi's martial art is fast and brutal melee with a juggernaut twist. And LOTS of multiple use strikes/blocks for both unarmed and blade and blunt attacks. However, dodging a blow is nearly unheard of, because of the rigid dogding style; It more based off of rolling with the punches and using the enemy against them, or countering.
Ah, yes, and I forgot; Arashi, being pyrokinetic, takes a strange approach; Igniting himself entirely when attacking. Bit of a shocker, to be fighting a living fireball of purple and furriness. With every hit leaving at least a third degree burn; At highest temps ( About the same heat as the surface of the sun), Arashi can cause fourth degree burns on contact, which is the instant evaporation of flesh and bone and skin. And in a furry combat scenario, fur.
