Orthrus

Orthrus (朝の祈り, Asa no Inori) is a ferocious curse utilized by the Etherious demon dog Kerbec.

Description
This curse allows Kerbec to utilize a pitch black dark energy. This energy flows like flames as he uses it, It will cover his shorts, Wrap around his head to appear as a makeshift crown, and shroud his feet to create clawed paws. When using this Kerbec's appearance will become more primal and animal like as he will grow incredible claws though for some reason they will not be covered in the curse. It increases his scences allowing him to smell or hear better which works great in conjunction with his Sound Magic as his hearing could rival the level of Cobra's fromOración Seis.
