Trivia

 * Some of these character skills is a direct reference and spoilers to Arc 5.
 * Most of the characters' moves have in-game exclusives that did not appear in either the light novel nor the anime.
 * Anastasia's ultimate is a combination and a subtle reference to Ricardo launching Wilhelm to the Hakugei and Julius fighting Petelguese.
 * All of Ricardo's moves has received in-game exclusives moves: He uses his claws to fight and he uses his Resonance Wave as his ultimate. This never appeared in neither the anime nor the light novel until Arc 5. Also, his "Leap" skill is a reference to the cut web novel in Arc 3.
