Episodes
Staffel 1
1Beautiful Agent
The first episode, titled "Beautiful Agent," introduces a post-apocalyptic world in the year 2036, where a major cataclysm has submerged most of Earth's landmass. The narrative follows Aika Sumeragi and her partner Rion Aida, who work as salvagers for the K2 company, retrieving technology and artifacts from the ruined cities beneath the sea. Their initial salvage operation is interrupted by a rival salvager named Gusto, establishing the competitive nature of their profession. Aika and Rion are subsequently assigned a mission by Gozo Aida, Rion's father and head of K2, to recover data on a dangerous new energy source known as Lagu. This mission leads them into direct conflict with the Hagen siblings, Nena and Rudolf, who lead an organization also seeking Lagu. The conflict escalates when Aika pilots a fighter jet to gather data on Lagu, with Rion having stowed away onboard. Nena Hagen leads a squadron to intercept them, and Lagu's energy is activated, emitting an electromagnetic pulse that disables Aika's aircraft. In response, Aika's golden Ultranate bustier activates, transforming her into a blue-haired form called Shivie Aika to manually restart the plane's systems. Despite this effort, Aika is left drained of energy and is subsequently captured by Rudolf Hagen, setting the stage for the next phase of the conflict. Aika's primary motivation throughout is her loyalty to K2, which she views as her home. Rion is driven by a desire to prove herself and support the company, which operates under old-fashioned business principles that keep it in debt. The Hagen twins are presented as antagonists seeking the power of Lagu to achieve their own ambitions, with Rudolf planning to use it to reshape humanity.
2Naked Mission
The episode continues Aika and Rion's search for the energy source known as Lagu. Their mission leads them into a confrontation with the rival salvagers Nena and Rudolf Hagen, resulting in Aika and Rion being taken captive aboard the Hagens' vessel. Rudolf Hagen explains the nature and potential of Lagu to Aika during her captivity. Aika makes a calculated decision to agree to Rudolf's proposition for a night in exchange for information, a choice that creates a temporary shift in the immediate power dynamic. Meanwhile, Rion manages to escape from the ship, seeking to regroup and find a way to rescue her partner. The episode introduces Gusto (referred to in some sources as Gastor) as another interested party also present on the Hagens' ship, positioning him as a potential factor in the unfolding events. A key aspect of the mission parameters established early in the episode requires Aika to operate without weapons or protective gear, forcing her to rely solely on her physical abilities and resourcefulness to navigate the dangers she encounters. The narrative focuses on the escalating conflict between the salvagers and the Hagen siblings, with Aika's capture serving as a central turning point. Rion's successful escape re-establishes an element of hope and sets the stage for a potential counter-operation. Gusto's presence on the antagonist's ship complicates the scenario, as his intentions regarding Aika's predicament are not immediately clear. The episode details the progression of the mission from a simple retrieval to a personal hostage situation, fundamentally altering the protagonists' objectives from finding Lagu to securing their own survival and freedom. The constraints placed upon Aika's resources highlight her personal capacity for overcoming adversity. The immediate consequence of the episode is the fragmentation of the heroines, with Aika isolated and in a precarious position while Rion works from the outside to mount a response.
3Takeoff Position
The team's mission to secure the pieces of the unknown technology continues as they travel to a remote island owned by their rival, Hagen. Upon arrival, the group splits up to maximize their search efforts. Aika and her assistant Rion investigate the island's airport, while their associates Gusto and Gozo infiltrate Hagen's mansion to gather intelligence. During their exploration of the airport, Aika and Rion encounter Hagen's young descendants, Rie and Rena. The girls provide information confirming that Hagen intends to use the completed technology for his own purposes, which aligns with the team's suspicions. This intelligence leads Aika and Rion to discover a hidden room within the airport that contains the next component of the device. However, they find the chamber is booby-trapped with explosives set to detonate within a limited time frame. The two agents work together to disarm the bombs and successfully retrieve the technology piece before the room is destroyed. Simultaneously, Gusto and Gozo are discovered during their intrusion of Hagen's mansion, leading to a physical confrontation with his security forces. They manage to overcome the guards and escape, acquiring additional knowledge about the mission in the process. The episode concludes with the team regrouping to assess their progress, having now secured two of the three required technology fragments. Aika's determination to beat Hagen to the final piece sets the objective for the continuing mission.
4Trial 4: A Flower Blooming in Space
Aika and her assistant Rion are reunited after being separated in the previous episode, only to find themselves drawn into the final stage of Hagen's plan. Hagen's objective is to extract the powerful energy source known as Lagu from the Earth's core while in space, intending to use it to reshape the planet and establish his dominion over it. The conflict moves to a space-based setting as Aika's team pursues Hagen to stop his scheme from coming to fruition. Aika is confronted by a formidable opponent in Neena Hagen, who now possesses a device that grants her abilities similar to those Aika previously derived from her own golden bra, which has been rendered inoperative. This development creates a direct parallel between the protagonist and antagonist, forcing Aika to adapt to a new combat dynamic. Rion, having been held captive, receives a direct explanation of the villain's intentions, learning the full scope of the catastrophe he plans to unleash upon the world. The episode builds toward a decisive final battle, with Aika and her allies committed to preventing Hagen from returning to Earth as its ruler. The immediate consequence is the escalation of the conflict into a direct confrontation that will determine control of Lagu and the future of the planet.
5Trial 5: The Golden Delmo Operation
Following the events of the previous conflict, the K2 organization's leader rewards Aika and her team with a vacation to a South Sea island. During their stay, Aika encounters a charming individual named Pierre, and the two develop a close romantic connection, spending considerable time together. The narrative progresses as this seemingly idyllic getaway is gradually revealed to be an elaborate trap. It is disclosed that Pierre is not the person they appeared to be, exposing the situation as a carefully orchestrated deception. The antagonists Hagen and his sister Nena are ultimately revealed to be the masterminds behind the ruse. The episode establishes that the Delmo organization, despite the disappearance of its former leader, continues to operate with the primary objective of seeking revenge against Aika. A secret operation has been specifically assembled with the goal of neutralizing her during her stay at the hotel. The immediate consequence of this revelation places Aika and her companions in a perilous situation, directly targeted by their persistent adversaries. This installment shifts the series' focus toward the lingering threat posed by the Delmo organization's remnants, setting the stage for subsequent confrontations.
6Delmo Operation: White Silver
The episode's central conflict is set in motion when Rie Petoriyacowa, who had been posing as an ally, reveals her true allegiance to the Delmo organization and orchestrates an ambush against Aika Sumeragi. Rie's primary motivation is to gather close-quarters combat data on Aika, a mission she personally oversees by recording the encounter with four Black Delmo operatives in a bathhouse facility. Simultaneously, Rion Aida and Shuntaro Michikusa are captured in a separate location through deception, and Gozo Aida is targeted in a bar where he is deliberately plied with alcohol to lower his defenses. Despite his intoxication, Gozo single-handedly incapacitates multiple Delmo attackers using improvised weapons and physical strikes, creating a turning point that allows him to later reunite with Rion. Aika's own fight progresses as she methodically defeats waves of Black and Blue Delmo operatives, using a combination of tranquilizer darts, thrown opponents as cover, and acrobatic maneuvers to bypass a barricade. She then confronts Rie directly, whose combat analysis initially proves effective until Aika disrupts her rhythm with an unorthodox hair-grab, leading to Rie's incapacitation. The immediate consequence of these parallel assaults is the neutralization of the Delmo forces guarding the facility's data room. This allows Aika to intercept a lone operative attempting to flee with the classified information, successfully retrieving the data disc and completing the mission's primary objective. With the data secured, Aika and her team are able to extract themselves from the Delmo facility.
7Break the Decisive Battle! Delmo Base!
The episode opens with the aftermath of a devastating attack on the K2 organization, their headquarters reduced to rubble and the Boss hospitalized with severe injuries. Rion Aida and the remaining K2 staff are left to mourn, as top agent Aika Sumeragi is believed to have perished in the explosion that destroyed the building. Motivated by grief and a desire for vengeance, Rion resolves to strike back at the Delmo Agency, the group responsible for the assault. Following advice from Shuntaro Michikusa, Rion and the salvager Gust Turbulance seek out a Class A agent for assistance, leading to the unexpected introduction of the mysterious agent Maypia. United by a common goal, this newly formed team—comprising Rion, Gust, Michikusa, and Maypia—launches a direct infiltration of the enemy's Delmo base. Their assault is driven by the belief that Aika is dead, fueling their determination to confront the Delmo forces head-on. However, the narrative's central turning point reveals that Aika is, in fact, alive. Having survived the explosion, she stages her own disappearance and independently initiates her own assault on the Delmo stronghold. This convergence of forces leads to a chaotic three-way confrontation within the enemy base. The climax of the episode sees Aika fully harnessing the power of the Lagu, her golden bustier, transforming into a more powerful state to combat the Delmo Corps and their leader, Rudolf Hagen. The immediate consequence is the decisive confrontation that determines the fate of the Lagu and brings the conflict between Aika and Hagen to its peak.
