City of Haze

From the Castlevania Wiki, the Castlevania wiki

The first Portrait in Portrait of Ruin. Found within minutes of entering the castle, this stage thrusts the player directly into the game with a Victorian-era town complete with demonic shops and shopkeepers. This stage contains mainly skeletons, bats, and Mini-Devils. The stage's boss is Dullahan, who appears as a giant suit of armor with a free-floating head.
