Living Spirit: Sky Beast (精生：空獣 Seisei: Sorajū) is a SIGNI class associated with green SIGNI. Like their counterpart, Living Spirit: Earth Beast, all Sky Beasts are titled "Phantom Beast" and named after the creature they represent, very often kinds of birds.
As their name suggests, Sky Beasts are exclusively real kinds of birds, and their designs are often based on such.
