10. Dgak - doctor
16. Xostor - seawave
3. WishmasteR - bio
Loreley is demo. Powder is a precursor.
ToX is ghost. At first I thought he might be the keeper, since there's a sun on her art, but no. He's mafia and played like mafia and was the ghost.
By process of elimination, Dragneel is bruno, as he's a good fighter.
Why is Xostor seawave? Because he's mafia, because the keeper is dead, and because the last vote exposed him.
Why is Dgak doctor? Because of the clue interpretation: broken Italian => Skype nickname => Michelangelo painted the Mona Lisa in Italy and gave it an Italian surname.
By process of elimination, WishmasteR is bio.
Actually, I hoped the maniac would think to kill Xostor with a double vote, especially after everything that happened.
