That and well in the novels

Spoiler for novels:

Their is much speculation thinking that touma has lucifer hidden in him since he had an evil aura come out of him scaring shit outta fiamma. Also the fact fiamma has thought that his imagine breaker is the holy gem that sealed lucifer support the theory. Any way its also been said that lucifer has a nickname of being called the "great dragon"

. I also have this message from someone who read the bible.

About this outfit is black coat and orange color t-shirt:

When the sky cover by dark-night,
A source of light begin to rise,
Piercing the dark and shine to land of man,
The light that begin the day.

This symbol of morning star, a frame of Lucifer.
However lucifer has name as saten too, the one bring mankind sorrow and dispair
