Summary[]

Season 1 (Emerald Arc)[]

The series begins with Mirei Koharu, a skilled and resourceful 18-year-old spy, carrying out a mission in her new hometown of Tokyo. During her assignment, she witnesses an unusual event — an alien spacecraft crash-landing nearby. Investigating further, Mirei discovers Kabutaro, a cat-like alien with mysterious abilities, who becomes her unexpected ally. As Mirei and Kabutaro get acquainted, the feline alien reveals that the crash was no accident. It turns out that Kabutaro possesses valuable information about an imminent threat to the galaxy — the activation of a powerful ancient artifact known as the Galactic Emerald. The duo embarks on a quest to prevent the artifact from falling into the wrong hands.

Along their journey, Mirei and Kabutaro encounter diverse characters, both allies and rivals. They assemble a team of individuals with unique skills and backgrounds who join their cause, forming an intergalactic group dedicated to protecting the galaxy. Mirei and her team travel to various planets, space stations, and hidden locations, searching for clues about the Galactic Emerald's origins, purpose, and how to neutralize its potentially catastrophic power. They face thrilling challenges, such as evading traps, solving puzzles, and engaging in intense space battles.

The main antagonist, a cunning and power-hungry individual, becomes aware of Mirei and Kabutaro's mission. They send their minions and mercenaries to thwart their progress, creating intense conflicts and battles. The antagonist's ultimate goal is to gain control of the Galactic Emerald's immense power for their own nefarious purposes. As Mirei and her team uncover more about the Galactic Emerald's true nature, they realize that its activation could have catastrophic consequences for the galaxy. The series builds up to a climactic final battle between Mirei's team and the antagonist's forces, with the fate of the galaxy hanging in the balance.

Following a thrilling and action-packed climax, Mirei and her team successfully prevent the activation of the Galactic Emerald, saving the galaxy from disaster. However, they realize that their adventures are not over, as new challenges and mysteries await them in the vastness of outer space, setting the stage for future seasons of the series.

Season 2 (Ruby Arc)[]

The story continues after the events of the Emerald Arc, where Mirei and her team successfully prevented the activation of the Galactic Emerald, saving the galaxy. However, they soon discover that their mission was only the beginning of a larger cosmic conflict.

The Ruby Arc introduces a new threat to the galaxy. A clandestine organization known as the Crimson Syndicate emerges, seeking to obtain a series of powerful ancient artifacts called the Stellar Rubies. These artifacts possess immense energy and have the potential to reshape the fabric of the universe if harnessed by the wrong hands. The Crimson Syndicate's leader, a mysterious and enigmatic figure, aims to use the Stellar Rubies to gain absolute power and dominance over all known realms.

Mirei and her team, now recognized as seasoned protectors of the galaxy, embark on a new quest to track down and secure the Stellar Rubies before the Crimson Syndicate can get their hands on them. Their journey takes them to unexplored planets, ancient ruins, and even the far reaches of the cosmos. Along the way, they encounter new allies, formidable adversaries, and unravel deeper secrets about the origins of the artifacts and the true nature of the universe itself.

The Ruby Arc explores themes of loyalty, trust, and the blurred lines between good and evil. As Mirei's team delves deeper into the conflict, they become entangled in a web of intrigue and deception, not knowing whom they can truly trust. The stakes are higher than ever as they race against time to prevent the Crimson Syndicate from assembling the Stellar Rubies and unleashing their cataclysmic power.

Throughout the season, Mirei and her team face numerous challenges, including treacherous traps, intricate puzzles, and intense battles against the Crimson Syndicate's agents. They must also confront their own inner demons and personal conflicts, testing the strength of their bonds and resolve.

The tension escalates as the Ruby Arc builds towards an epic showdown between Mirei's team and the Crimson Syndicate's leader. The fate of the galaxy hangs in the balance once again, as the heroes fight to protect not only the Stellar Rubies but also the very fabric of reality itself.

The season concludes with a thrilling climax, where Mirei and her team ultimately thwart the plans of the Crimson Syndicate, but not without sacrifices and unforeseen consequences. As they emerge victorious, they realize that their journey is far from over. New adventures and challenges await them in the vast expanse of the universe, setting the stage for future seasons and further exploration of the Galactic Emerald series.

Voiced by: Daisuke Ono (Japanese); Matthew Mercer (English)

Orion is the first alien encountered by the Lunar Explorers. Hailing from a hidden realm within Mercury known as "Aquatopia," Orion's upbringing in a royal environment has shaped his initial demeanor, which may come across as prissy, childish, spoiled, and self-centered. However, beneath this exterior, he possesses a genuinely sweet, pure-hearted nature and cares deeply for others. Orion's sensitivity to the feelings of those around him and his overprotectiveness during conflicts demonstrate his innate compassion.

Despite his occasional unintentional bluntness, Orion values honesty and speaks his mind, even if his words sometimes inadvertently hurt others.

  • Sayuri Suzu

Voiced by: Karin Kagami (Japanese); Laura Bailey (English)

Sayuri is the second alien encountered by the Lunar Explorers. Hailing from a vibrant realm on Saturn known as "SaTune Land," Sayuri's upbringing immersed her in the world of electro-pop and DJ music.

Sayuri embodies a peppy and adventurous spirit, often wearing her emotions on her sleeve. She is celebrated for her fearlessness and audacity, frequently plunging headfirst into perilous situations without hesitation. Although her daring nature occasionally lands her in trouble, she always manages to find a way to save herself. While she may come across as menacing at times or boast about her abilities, it's all in good fun. At her core, Sayuri is a kind-hearted and fun-loving individual.

With a deep passion for singing and dancing, Sayuri has honed her skills in both disciplines from a young age, resulting in her exceptional physical fitness. She compares hip-hop moves to the art of dance and often breaks into dance when filled with excitement. However, her love for dance and physical activity has also made her quite gluttonous, frequently discussing her favorite foods. Sayuri is known to have an insatiable appetite, relishing in a variety of treats such as cakes, candies, and even potato chips. She enthusiastically indulges in soda as well.

Sayuri can be characterized as slightly airheaded, often caught up in the joy of battlefields and breaking into dance, momentarily diverting her attention from the enemy. She tends to focus on the "big boss" rather than the lesser adversaries, favoring a head-on approach over nuanced strategies. Unfazed by the Queen Rani employee handbook, she believes in boosting her enemies and then blasting them repeatedly as her winning strategy for war. Additionally, Sayuri possesses a mischievous side, often playfully snatching snacks from her bandmates and surprising her father with chocolate-covered honey on Valentine's Day.

Through Sayuri's presence in the series, she brings an infectious energy, lightheartedness, and an unwavering spirit of adventure. Her character arc showcases the balance between fearlessness and responsibility, and the importance of embracing one's passions while remaining mindful of the consequences. As Sayuri navigates the challenges of Galatopia alongside the Lunar Explorers, her exuberance and playful nature become key assets, providing moments of levity and inspiration for her comrades.

  • Mayumi Marshall

Voiced by: Emiri Katou (Japanese); Kari Wahlgren (English)

Mayumi is a spirited alien girl hailing from a vibrant city in Mars called Astropolis. As the third alien encountered by the Lunar Explorers, she becomes their friendly rival. Mayumi possesses striking red hair that remarkably changes its facial expression to reflect her mood. She wields fireball-infused hands, harnessing the power of fire energy to collect treasures with the goal of resurrecting the Spirit of Mars. Her intention is to unleash its destructive force upon her enemies, particularly the Lunar Explorers. However, Mayumi has a weakness without her element of heat.

Initially, Mayumi was an escaped prisoner from Mars. While she was initially arrested for crimes such as stealing tangerines to support her twin sister Maya's impoverished family, it was later revealed that Maya had taken responsibility to protect her. During Mayumi's trial, Maya attempted to convince the judge that she was equally guilty, but Mayumi, fearing for her sister's fate, claimed it was a lie. This incident sowed the seeds of Mayumi's grudge against the Lunar Explorers. Her animosity grew when they unknowingly disrupted her computer code, causing her to chronicle over 3,000 unfavorable events involving the Lunar Explorers and even their Planetary Friends (accidentally). Mayumi often reads these entries aloud, citing the entry code number, and delving into flashbacks to showcase the incidents. Despite her jealousy, Mirei remains oblivious to the true reasons behind Mayumi's rage.

Similar to Mirei, Mayumi harbors affections for Touma, which at times appear stronger than Mirei's own feelings. Throughout the series, there are comical instances of Kuromi's fantasy sequences involving Touma. In the Ruby Arc, Maya creates a dakimakura (body pillow) with Touma's face for Mayumi. During an episode, Mayumi utilizes her powers to transform her outfit into an elegant, phoenix-like dress, hoping to dance with Touma. While Touma shows interest in Mayumi, a spell cast upon her has a Cinderella-esque effect. If she fails to return to the spell-casting circle before all the magical candles burn out, she reverts to a smaller child. Consequently, she must abruptly leave the dance with Touma, but he bids her farewell with a hand kiss.

Despite her flaws, Mayumi possesses a good-hearted nature. She displays aspects of laziness, anger, and gluttony, yet maintains a touch of femininity alongside her tomboyish characteristics. Mayumi takes great interest in weddings, fancy fashion, and romance novels and manga. She enjoys napping and designing wedding dresses, although Maya openly expresses his disapproval of her fashion sense. Mayumi considers herself to be high-maintenance, often insisting that Maya and anyone she casts fire magic on refer to her as "Mayumi-han." She occasionally refers to herself as "Commander Mayumi." Additionally, Mayumi possesses the ability to fly.

  • Maya Marshall

Voiced by: Satsuki Yukino (Japanese); Kate Higgins (English)

Maya is the fourth alien encountered by the Lunar Explorers, hailing from Astropolis. She is the twin sister and sidekick of Mayumi, sharing a close bond with her. Maya also possesses the ability to fly, showcasing her unique powers. Throughout the series, Maya exhibits a flirty demeanor towards certain individuals in certain episodes. Despite their occasional conflicts, they share a deep sisterly love, fostering a strong sisterhood.

Similar to her twin sister, Maya maintains a journal where she records memorable moments they share. In the first season, Touma burns the journal, but Maya somehow manages to retrieve it in the second season when they break out of jail.

Her birthday is confirmed to be on February 29. Maya's name holds a playful pun, as in Japanese, "Maya" can mean "a small flame." In one episode, she attempts to flirt with Mirei. Maya also exhibits a conscience, as she is seen delivering newspapers and giving rides to children on occasion. Moreover, Maya possesses a unique ability to sniff out certain items, often involved in their safekeeping. The initial encounter between Maya and Mayumi took place at a beach on Mars.

  • Julio Jesse

Voiced by: Yoshitsugu Matsuoka (Japanese); Greg Ayres (English)

Julio is the fifth alien encountered by the Lunar Explorers, originating from EcoJova, a vibrant rainforest-like realm within Jupiter. He possesses a brave and kind-hearted nature, deeply passionate about animals, nature, indigenous culture, and his own family. Julio carries a genuine concern for the preservation of nature and becomes worried about its potential destruction. As a result, he takes on the responsibility of ordering flowers to collect and protect them.

Julio forms numerous friendships with both the Lunar Explorers and their Planetary Friends. While they share a strong bond, particularly with Kabutaro, Orion, and Touma from the boys' club, he maintains connections and interactions with other characters as well.

  • Erisa Aino

Voiced by: Aoi Yuuki (Japanese); Kate Bristol (English)

Erisa is the sixth alien encountered by the Lunar Explorers, originating from the kingdom of Minervia, an enchanting realm on Venus. Erisa presents herself as loquacious, enthusiastic, talkative, sweet, and kind, earning her the reputation of being the "Venusian Sweetheart" and "Princess of Venus" among the public. However, behind this facade lies a deeply flawed character. In reality, Erisa is portrayed as spoiled, vengeful, heartless, unpleasant, manipulative, calculating, and even psychopathic. She exhibits no hesitation in ruining the lives and careers of anyone she deems inferior.

Erisa comes from a royal family, with her mother, father, and older brother being part of her life. Despite her enmity towards others, Erisa harbors a romantic interest in Kabutaro. She often fantasizes about engaging in lovey-dovey dates, getting married, having a sexual relationship, and even having four children. The Lunar Explorers find Erisa's fantasies to be rather gross because of her and Kabutaro's differentiating species.

Interestingly, Erisa assumes a big sister role towards Mirei, displaying a complex dynamic between them. At one point, Erisa accuses Mirei of being a spy, but later on, she decides to use her singing abilities to assist the Lunar Explorers in protecting Galatopia.
