Castlevania Double Pack: Aria of Sorrow / Harmony of Dissonance is a Game Boy Advance action-adventure compilation from Konami. It combines two side-scrolling vampire-hunting adventures on one Game Pak, each centered on exploration, monsters, and gothic castle labyrinths.

• Cleaned, tested, and guaranteed to play. Authentic cartridge.
• Harmony of Dissonance follows Juste Belmont as he searches Dracula’s castle for relics and learns powerful spells.
• Aria of Sorrow takes place in 2035, with Soma Cruz drawn into a mysterious castle during the first solar eclipse of the 21st century.
• Aria of Sorrow features soul collecting as a core mechanic, letting Soma gain abilities from defeated enemies.
• The package brings together two portable Castlevania entries built around exploration, combat, and ability-based progression.

The compilation pairs a Belmont family storyline with Soma Cruz’s later-era Castlevania arc, giving the release two distinct points in the series timeline.
