Aurelio

Corrupted clone of Elio that was infused with the essence of the demon of Wrath. He was created to kill Lio and steal his solar powers but he turned against his creators and fled with his caretaker, Vasti. Still wants to punt Lio into the sun though

hes a physical manifestation of Lio’s negative emotions, (mainly his hatred towards the demons that destroyed his village and his inability to do anything to save anyone)

as such he hates all demons (with the exception of Vasti) and will not hesitate to kill any he sees on sight (This has earned him The nickname “the angel of death” among them and their peers), and he sees Lio as weak

hes the complete opposite of Lio: serious, independent, aggressive, pragmatic and arrogant

he still often gets confused for him though since they look alike. He hates that

has a bunny named Lucifer and travels with Vasti
