Castlevania: Aria of Sorrow (キャッスルヴァニア ~暁月の円舞曲~) is a 2003 side-scrolling platforming video game developed and published by Konami. It is the third installment of the Castlevania series on the Game Boy Advance.
Aria of Sorrow is set in the year 2035, when Dracula has been sealed away after a battle in 1999. The plot follows the journey of Soma Cruz, a teenager granted occult power as a result of being a potential vessel of Dracula's reincarnation, as he battles dark figures that wish to inherit the undead lord's power. The game incorporates the same combination of elements from platform games and role-playing video games as in a previous game Castlevania: Symphony of the Night. Aria of Sorrow introduces several features to the series, such as the "Tactical Soul" system and employs a futuristic storyline in contrast to the medieval setting of many other Castlevania games. It was released in May 2003 for the Game Boy Advance.
