Japanese version of Harmony of Dissonance. Graphically superb and fluid, gameplay is solid. Slightly below Aria of Sorrow but still an excellent Metroidvania.

Castlevania - Byakuya no Concerto (GBA) price, value & rarity
Original Japanese edition of Harmony of Dissonance, released in June 2002 under the Byakuya no Concerto title, IGA's first iteration on GBA after taking over the Castlevania unit. Konami rigid case and a dedicated Japanese obi, Ayami Kojima cover art in its native printing. Japan run was short relative to the following year's Aria, which makes a copy with intact obi in clean shape clearly harder to track down outside the country.
Memorable bosses
Two overlaid castles echo each other in this quest, where Juste Belmont darts along at high speed, whip cracking. His guardians, from the giant stone Talos to the writhing clump of Legion, demand juggling speed with spells combined from relics. More nimble than contemplative, these duels bet on agility and offer immediate combat thrills, served by detailed sprites.
Is Castlevania - Byakuya no Concerto still worth playing in 2026?
Harmony of Dissonance stands out thanks to its lighter and smoother palette, its mirrored two castle structure and a faster pace compared with Circle of the Moon. The elemental power system delivers a more expressive toolbox and untangling the layout across both dimensions stays satisfying. The soundtrack arguably falls behind the other GBA entries and some players miss a higher difficulty, but the whole still adds up to a solid metroidvania to recommend between Circle of the Moon and Aria of Sorrow.
