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. 
Backbone in my blood
Las agallas que corren por mis venas
Avec le courage dans mon sang
Nel mio sangue scorre la determinazione, reason
Espinha dorsal no meu sangue
Решимость течёт у меня по венам.
