Spoiler for How Yuji looks like while being possessed :

He should still look like yuji with a different eye or expression. he is surrounded by black fire and casting a stunning silver shadow whenever he moves(he emits silver white light while surrounded by a aura of black flame, like some kind of half divine angel from heaven and half thrice damned demon from hell; a powerful and fitting yet sharp contrast he creates in the minds of reader) . it is fairly fitting that in one of his first appearances he descended from above floating down to greet his followers while being encased by a divine silver light and surrounded by a torrent of sinister black flame as he slowly descended to the ground like some god , while the members of Bal Masqué kneeled before their lord who has finally returned. It is also mentioned that many members of Bal Masque like Hecate for example, actually see the Sairei no Hebi the being that inhabits yuji (or "The Snake of the Festival" in English) as a god rather than a mere leader that leads them. Basically that whole scene in the novel was to show you that the new yuji is the bad-ass God of the Bal masques and to show-off his powers.

I believe that The Snake of the Festival is in control of yuji 's body, since it shows that the mind of the real yuji is unconscious or asleep but may still influence the decision made by the spirit. Besides The Snake of the Festival has a high respect for yuji and would perhaps honor his wishes. Bottom line is that right now The Snake of the Festival doesn't seem to be a really bad person but he is about to do things which will cause great conflict/turmoil in the world for his own ends. In the end only time will tell whether he is really evil or not, because right now we don't know enough about him to make a solid judgment.
