Ryu Natsume is a unique member of The Cat’s Whiskers. He doesn’t experience trap reactions when using phantometal and his past is wrapped in mystery. One day, Ryu finds a kitten and brings it home. 
That's why we're doing the stage battles.
Dafür sind die Bühnenkämpfe doch da.
Para eso son las Stage Battles.
Le battaglie servono a questo.
É por isso que fazemos
as batalhas de palco.
Поэтому и нужны баттлы.
