Fabled

The Demonic Roaring Gods are a set of Monsters currently released only in Japan as a Duel Terminal Promo. There are currently only 3 Demonic Roaring God cards, but all three work in combination. Demonic Roaring God Rulee can be discarded by Demonic Roaring God Galbath and both effects will be activated, whereas Demonic Roaring God Grimro is a catalyst for using the other two. It should be noted that, although these creatures are "Demonic", they are all Light Monsters.
