Ar nosurge: Ode to an Unborn Star[a] is a Japanese role-playing video game developed by Gust and published by Koei Tecmo.

An extended version containing all of the game's downloadable content (DLC), Ar nosurge Plus, was released worldwide the following year on the PlayStation Vita.

A remastered high definition version, Ar nosurge DX, was released in Japan in March 2021 for the Nintendo Switch, PlayStation 4 and Microsoft Windows.

[6] The game employs a turn based battle system with timed button press elements that amplify effectiveness.

Only two characters participate in a battle at the time - Delta or Earthes as the attacker/defender, and Cass or Ion who stands back to charge their "Song Magic" special move.

[7][2] The battle transitions to the enemy phase, where the player must defends through time button presses to reduce damage aimed at Cass or Ion.

[2][7][3] The rest of the game's gameplay modes more closely resemble a visual novel, largely revolving around reading text and choosing from dialogue trees or other text-based options.

[4] The player is also given the option to equip "Genometrica Crystals" that are obtained through progression of the Genometrics segments, which give stat boosts for the game's battle system.

[8] Morale is generally low for its inhabitants – they long to live on in nature again, the ship is running out of resources, and they've been unable to find a new planet to sustain them.

[8] Additionally, they're under attack by a fairy-like race of humanoids called Sharls, who, with their innocent appearances and power of "Song Magic", lure people away to abduct them.

[12] Delta, an elite fighter from the organization of PLASMA, travels with his childhood friend Cass, who has the ability to wield song magic.

[16] The game was meant to mix the anime style of Gust's other main franchise, Atelier, while added a more in-depth science fiction story element to it.

[17] Some story events, such as the "Purification Ceremony" scenes, feature sexual overtones and innuendo; Tsuchiya implemented this to create more realistic interactions and relationships between characters.

[6] The game's battle system was developed to be flashy in presentation to hold the player's attention, but simple and quick in execution, as to keep the focus on the story and characters.

[24][25] North American publisher NIS America released a limited edition on their online store that included a copy of the game, the soundtrack, a hardcover art book, and a poster.

[33] Another enhanced release, Ar Nosurge DX, was announced in 2020 for the Nintendo Switch, PlayStation 4, and Microsoft Windows platforms.

[34] Initially announced for a January 2021 release date, it received a small delay to March 4, 2021, for Japan to address some minor quality issues.

Characters you'll grow to love change alongside your own, and a multitude of communicative sources...make it easy to become invested...while it doesn't break the glass ceiling of video game narrative design, it certainly leaves its hand prints across the stretch.
