Raita is one of the main three antagonists in Everlite, and is very mysterious. He appears in several different rooms, hanging from the ceiling for a split second. He rests in a slumped-over position, and his mask has several lines on the inside. He has the second most jumpscares in the game, behind Tara. He also appears to be able to levitate, as he is never seen walking.
Some speculations are that the Waking Shadow is simply Raita in a separate form, as it possesses the same slumped-over pose. This, however, is unlikely, as no other phantoms can take a separate form.
