Castlevania: Harmony of Dissonance is the second Castlevania game to appear on the Game Boy Advance. Juste Belmont and his friend Maxim are drawn to the newly resurrected Dracula's Castle in order to save their mutual friend Lydie, although it remains to be seen who will be saving whom.

This run plays through the Boss Rush mode using Simon Belmont, the original hero of Castlevania. Simon is pretty slow, but he still powers through the bosses with massive amounts of cross abuse.
