Setting and characters
Magical Starsign takes place in the fantasy world of the Baklava solar system, a planetary system composed of six planets that orbit a sun. The five closest planets to the sun each represent a different magical attribute, also known as a starsign, and host vastly different landscapes and civilizations: Razen (fire), Gren (wood), Puffoon (wind), Cassia (water), and Erd (earth). The sixth and most remote planet, Kovomaka, is home to Kovomaka Kingdom and Will-o’-Wisp Academy, a school headed by Principal Biscotti where aspiring sorcerers are taught magic. Within the sun, there is Nova (light) and Shadra (darkness), which overlap in parallel dimensions and alternate in a cycle akin to day and night.
The player controls six apprentice magicians in Magical Starsign: Lassi, a scatterbrained rabbit from an immigrant community who uses wind magic; Mokka, a deadpan ancient robot purchased by Biscotti who uses earth magic; Chai, a salamander who uses wood magic, making him an oddity among salamanders who typically cannot evoke magic. Pico, a hot-blooded ōendan member who taught himself fire magic to support his family; Sorbet, the academy's top student from a destitute family who uses water magic; and the player-named protagonist, who can be assigned either light or dark magic. They are all enrolled in Will-o'-Wisp's Class B, mentored by the capricious yet powerful sorceress Miss Madeleine. The primary antagonist of the game is Master Kale, an old student of Madeleine's who, leading a band of astro pirates, plots to destroy the Baklava system by fulfilling an apocalyptic prophecy.
Plot
The students overhear Principal Biscotti ordering Miss Madeleine to travel to Puffoon and confront Kale, whose pirates have been causing trouble across Baklava. Three months go by and Madeleine has made no contact with the academy, which pushes Lassi to find her using the academy's secret stash of rockets. Her classmates give chase, getting scattered across Baklava in the process. The protagonist reunites with Lassi on Erd, teaming up to procure a new rocket capable of interplanetary travel. On their journey to find the other students, they make enemies with Kale's accomplice Chard and his pirates, who have taken Madeleine to Razen. They eventually discover that Madeleine, among many other magicians, was arrested by Puffoon's Space Police. Upon reaching Razen, the group accidentally foil Sorbet's plan to save Madeleine by pretending to cooperate with Kale, who uses a spell to teleport his crew and the magicians he abducted into the sun.
Confirming that the pirates and Space Police are working together under Kale, the students set out to find the five millennium gummies, magical items that will let them enter the sun. Along the way, they learn from Baklava's king Suspiro that Kale used to work in his entourage, until the public revolted out of fear that their old customs would be lost. Kale then discovered a grimoire authored by the late archmagician Craaken, who predicted that the universe will be reborn when a worm named Shadra devours the sun and produces a new one. Believing the public is incapable of keeping Baklava alive, Kale resolved to accelerate the apocalypse by nourishing Shadra with the magical power of magicians.
Landing on Nova, the planet of light inside the sun, the students pursue Kale into another dimension containing Shadra, the planet of darkness and the worm Shadra's namesake. They defeat Kale in the worm's den where Madeleine is trapped, and a battle against a metamorphosed Shadra ensues. Upon defeating it, the sun is enveloped in a light that stops the apocalypse. However, Madeleine passes away, hoping her students will learn from the friends they made on their journey. The group are then escorted by the Space Police, rectified by former general Knucklestorm and his daughter Brie Pourri, on their way back to Kovomaka.
In the game's epilogue, Pico drops out of Will-o'-Wisp in his eighth year to explore the galaxy, while Sorbet graduates with honors and enlists in the Space Police. Mokka allows Lassi to reassemble him into a rocket, which she lends to the protagonist after detecting a signal in the far reaches of space, and Chai sneaks inside Mokka before takeoff.
