Revolte

Revolte is a demon warlord and an expert swordsman. His unique demon physiology allows him to skilfully wield four swords at once. His blades were magically forged and allow him to freely alter their weight so they can be «lighter and pointer than a feather» or «as heavy as a boulder» at a moment's notice. However, if he is unable to maintain magic in his swords, they become brittle and easily breakable.
