Castlevania: Aria of Sorrow is a 2003 action role-playing game developed by Konami Computer Entertainment Tokyo and published by Konami for the Game Boy Advance. It is the 20th main entry in the Castlevania series, as well as the third and final game produced for the system. Producer Koji Igarashi, who had led the production teams for previous Castlevania games, oversaw Aria of Sorrows development in parallel with its predecessor Castlevania: Harmony of Dissonance (2002). Michiru Yamane returned to compose the music alongside Takashi Yoshida and Soshiro Hokkai. Director Junichi Murakami was new to the Castlevania series.

In contrast with other Castlevania titles taking place in the late medieval period or the early 20th century, Aria of Sorrow is set in 2035, decades after a climactic war resulted in Dracula's permanent demise and his castle being sealed in a solar eclipse. The plot follows the journey of Soma Cruz, a teenager granted occult powers, as he is trapped in the eclipse and encounters dark figures who wish to inherit Dracula's power. The game has been described as an action-adventure game with elements of role-playing games. Aria of Sorrow introduces several features to the series, such as the "Tactical Soul" system that enables Cruz to absorb the properties of defeated enemies, as well as a full New Game Plus mode.

Aria of Sorrow was released in May 2003. Although it sold poorly in Japan, selling 27,000 units nearly one month after its release, it was commercially successful in the United States, with more than 158,000 units sold in the three months following its release. Aria of Sorrow received universal acclaim, with praise for its visuals, gameplay (particularly the Tactical Soul System), music, and level design. Some critics considered it the best Castlevania game since Symphony of the Night (1997), as well as one of the best Game Boy Advance and Metroidvania genre games.

Konami released a sequel, Castlevania: Dawn of Sorrow, in August 2005. It incorporated many elements from its predecessor, including the "Tactical Soul" system. Aria of Sorrow was re-released as part of the Castlevania Advance Collection on September 23, 2021 for the Nintendo Switch, PlayStation 4, Windows, and Xbox One alongside Castlevania: Circle of the Moon (2001), Harmony of Dissonance, and Castlevania: Dracula X (1995).

Gameplay

Aria of Sorrow features a 2D side-scrolling style of gameplay where the player controls the onscreen character from a third-person perspective. The game has been described as an action-adventure game with role-playing elements such as characters levelling-up each time they earn a set number of experience points from defeating enemies; each "level" gained increases the character's statistics, thus improving their performance in battle. Statistic examples include hit points, the amount of damage a character can receive; magic points, which determine the number of times a character can use magical attacks; strength, the power of a character's physical attacks; and intelligence, the power of a character's magical spells. Upon encountering an enemy, the player can use a variety of weapons to attack and defeat the enemy. Despite the game being set in 2035, the available weapons are largely medieval, including swords, axes, and spears; though a handgun is available. These weapons differ in their damage output, the range of the weapon, and the speed of the attack. Items and other accessories can be found by defeating enemies or by purchasing items from the game's shop.

Similar to previous games in the series, Aria of Sorrow is set within Dracula's castle, which is divided into several areas that the player traverses. These areas feature different components, such as different enemies, varying terrain characteristics, and a unique piece of theme music. Similar to most platform games, progression between areas is limited by the abilities the player has. While the method in which the player progresses through the game is initially linear, the player's options become more diverse as the number of character abilities increases.

Tactical Soul Aria of Sorrow introduces the Tactical Soul ability system to the Castlevania series. It involves absorbing the souls of enemies in order to gain additional abilities. Save for a few exceptions, all types of enemies in the game can eventually yield a unique soul that can be absorbed by the player. The rate at which enemies' souls are obtained varies between enemies. Players can trade souls between two Aria of Sorrow cartridges using two Game Boy Advance consoles and a link cable.

Souls provide a variety of effects, and are separated into four categories: Bullet, Guardian, Enchant, and Ability souls. Bullet, Guardian, and Enchant souls are identified with the colors red, blue and yellow respectively, and the player can only have one of each type equipped at any given time. Bullet souls are Soma Cruz's replacement for sub weapons in this game, and enable the player to consume a set number of magic points to use an ability, often some form of projectile. Guardian souls provide continued effects, including transforming into mythical creatures and summoning familiars. Guardian souls continually drain magic points as long as they are active. Enchant souls are continuously active as long as they are equipped, and provide either an increase in statistics, or abilities such as the ability to walk on water. The fourth type, Ability souls, are treated differently from the other three types. They originate from one-of-a-kind enemies in the game, and once obtained, they remain active as long as the player does not specifically disable them, not consuming any magic points.

Additional modes Aria of Sorrow includes additional modes of play that display elements not seen in the game's primary scenario. The New Game+ option allows a player that has completed the game to replay the game with all equipment, levels and souls the player had acquired in a previous file. Additionally, the player can opt to start the game in Hard Mode, offering the same gameplay at a higher difficulty level.

Two other modes offer alternatives to the standard gameplay. Boss Rush mode involves the player facing against all of the game's bosses in quick succession, and is unlocked after the player completes the game once. Julius Mode is an additional mode of play unlocked with the same method. The player takes control of Julius Belmont, the member of the Belmont clan featured in the game.

Plot

Setting

Aria of Sorrow takes place in the fictional universe of the Castlevania series. The series' premise is the conflict between the vampire hunters of the Belmont clan and the immortal vampire Dracula. In 1999, thirty-six years before the start of Aria of Sorrow, Dracula was defeated once and for all by the Belmont clan, and his powers sealed into a solar eclipse. Shortly after Dracula's death, a prophecy was made that Dracula's reincarnation would come to his castle in 2035 and inherit all of his dark powers. This prophecy acts as the driving force behind the plot of Aria of Sorrow, and is the primary motivation of the supporting characters to be present. The game takes place in Dracula's castle, the most common setting for the series, with the castle divided into numerous areas that the player traverses over the course of the game.

Characters The protagonist and primary playable character of Aria of Sorrow is Soma Cruz, a transfer student studying in Japan who possesses the "power of dominance", which allows him to absorb the souls of monsters and use their abilities. He is initially accompanied by his childhood friend, Mina Hakuba, the daughter of the priest of the Hakuba shrine. Over the course of the game, Soma meets additional characters that aid him in his quest: Genya Arikado, an enigmatic government agent and disguise for Alucard, the son of Dracula; Yoko Belnades, a witch and member of the Belnades clan; J, an amnesiac man drawn to Dracula's castle; and Hammer, a soldier from the military ordered to investigate the events occurring at Dracula's castle, although he abandons this mission and sets up a shop to sell Soma equipment (potions, weapons and the like). Graham Jones, a missionary who believes he is Dracula's reincarnation, serves as the game's antagonist.

The characters were designed by Ayami Kojima, who had previously worked on the characters in Castlevania games such as Castlevania: Symphony of the Night and Castlevania: Harmony of Dissonance. Due to the game being set in the future, Kojima's designs are notably more contemporary, utilizing modern clothing, in contrast to the medieval attire that characters from previous games wore.

Story The story begins in the year 2035, when Soma Cruz is visiting Japan as a transfer student and living near the Hakuba shrine. During a solar eclipse, he visits the Hakuba shrine with his childhood friend Mina Hakuba. He and Mina are then drawn into the eclipse, landing in a mysterious castle, where they meet a government agent named Genya Arikado. Arikado reveals that they are in Dracula's castle. After a group of monsters appear and are dispatched by Arikado, one of the monsters' souls is absorbed by Soma. Arikado explains this as the awakening of Soma's "power of dominance". Arikado then directs Soma to enter the castle and seek "the master's chamber".

As Soma proceeds through the castle, he confronts several characters, each present due to a prophecy related to Dracula's powers. Graham Jones, a missionary that has come to the castle, befriends Soma. Graham explains the nature of the castle and reveals that Dracula, long thought to be immortal, was destroyed for good in 1999, and that his powers will be passed down onto his reincarnation. When Soma proceeds further into the castle, he meets the witch Yoko Belnades, who is present on the orders of the Roman Catholic Church. Yoko is looking for Graham, who she believes is dangerous and the inheritor of Dracula's powers. She clarifies the nature of Soma's powers, revealing that they are not necessarily evil, but inherent to Soma himself. Later, Soma encounters Hammer, a member of the Army ordered to come to the Hakuba shrine. He has forfeited his mission, however, in favor of selling goods. He becomes Soma's vendor, selling numerous goods to aid Soma's mission. A mysterious man then accosts Soma, asking about the nature of Soma's dark power. When Soma continues to converse with him, the man reveals that he has amnesia, and the only thing he remembers is his name starts with "J".

Soma meets Graham again, and questions him on Yoko's suspicions. Graham claims he will receive Dracula's powers, believing himself to be Dracula's reincarnation as he was born on the day Dracula was slain. Graham inquires as to the nature of Soma's powers, to which Soma responds that he has "the power to rule," causing Graham to panic and flee. Concerned, Soma confides this incident to Yoko, who recommends that Soma join her in stopping Graham. As Soma proceeds further through the castle, he comes upon a scene of Graham stabbing Yoko with a knife. Graham retreats, and Yoko warns Soma of Graham's power. Arikado arrives, promises Soma he will look after Yoko, and demands that Soma pursue Graham. Soma meets "J" again, who reveals he is Julius Belmont, the man who defeated Dracula in 1999. As he leaves, he remarks that he knows something about the current situation, but does not elaborate.
