Taken from Gods Eater Burst's database:
Red all over like a flame, it is an Aragami with an exoskeleton, closely resembling a Varja. Able to produce an external heat-emitting core. It is known to be more vicious than the ogretail. Hails from the eastern part of the American continent.
The heat is emitted from the tip of its tail: as this extends the ogretail's already long reach, one should take care not to misjudge this distance.
