It could be an inner demon, as someone sealed inside him.
However, both times we have seen this demon in chains [83- http://mangacow.co/Black-Haze/83/17/ , 88- http://mangacow.co/Black-Haze/88/22/], Ruby's power has been involved. The spear had Ruby's mana and now he's fighting her right now. It could be that her power is triggering these visions or they are the representation of Ruby's power.
Ruby has the same eyes as the demon and both have horns. They could be blood related and/or the same demon species. Hence why, through Ruby's power, Rood is having these visions. There's probably a connection between them [Rood & Ruby].
There are lots of possibilities right now.
I think Rood is a demon, not one created by that ritual or anything along those lines, but an original demon by blood. The thing is why would a demon have another demon sealed inside him? It makes little sense unless they are simply his own powers sealed and this is the visual representation we see. Though then why refer to Rood as a different person/entity if they are one? 'My brethren' implies they are not one.
Rood might be looking into Ruby's power or maybe even the original source of Ruby's power. From Ruby we have seen how demons can share or grant power... What if what we are looking at is the demon king or the demon king's son [brethren to Rood] and the source of Ruby's power. If the demon king is the source of Ruby's power [probably through blood], it would explain why it can recognize Rood as what he is, and Ruby can't.
Point is we are looking at how this demon, who's connected to Rood somehow, is in trouble/has been sealed.
Keep in mind, the long haired guy is/was old friends with Dio. Dio felt nostalgia from Rood, implying they are the same person or they are related. We have confirmation that they are at least related, though we have yet to find out if they are the same.
Btw, Blow form is [Insert real demon name here]'s human form. While Rood form is similar to how Dio has a small form. Long haired guy form may be his actual demon form if they are one.
- If we assume Rood form is similar to Dio small form, one which Dio transformed to when he was weakened and needed to recover from the Black Mana's attacks, Rood form and the evidence of the broken horned demon in chains, could imply something very harmful occurred to Rood causing him to remain in his human form for so long. He would have to be unsealed and recover accordingly [speculation- maybe he can only recover in the demon world, probably due to mana differences, or something like that].
- Another way to speculate about the possibilities is the following- Rood form = Human Form. Blow form = Dio small dragon form [weakened]. Long haired guy form = real demon form.
One question to you all, what do you think, is the chained horned demon the demon form of the long haired guy or are they different entities?
One more thing... the author has purposely avoided showing the long haired guy's eyes. If they were blue like Blow's eyes, they may spoil much about Rood and him. Though if they were yellow slit eyes, it could bring forth further speculation that Rood has a demon form with eyes like that.
