Plunderer

Hina, searching for answers after her mother's mysterious disappearance, travels to a town in pursuit of a lead on the Legendary Ace. There, she meets Nana, the owner of a local tavern, and Licht, a large man with a tendency toward inappropriate behavior.

Licht, a legendary warrior known as the Ace of Flashing Strikes, rescues Hina from a corrupt military officer. Hina believes he is the person her mother told her to seek, though Licht appears uncertain about her claims.

Lynn and Pele, stationed in a quiet, uneventful town, come across a mysterious pudding vendor whose appearance closely resembles that of the notorious outlaw Ace, sparking their suspicion and concern.

Licht is struck by the tranquility and contentment of the residents in Lynn's town, but this harmony is disrupted when Jail, Lynn's commanding officer, arrives.

Jail unveils his true power, reaching a strength level of 12,500 and surpassing Licht in speed, his area of expertise. With the townspeople and Lynn watching, Licht finds himself in a dire situation.

Hina, following a hunch and with Nana's help, tracks down Licht and encounters Pelmo, a determined woman pursuing her long-held ambition, which soon reveals unexpected dangers.

Lynn and Pele encounter Licht, creating a tense dynamic among the three. To ease the growing tension, Nana suggests a cooking contest to add some levity to the situation.

Jail, Lynn, and Pele arrive in the deserted town of Linden, where they find evidence that all the residents have been wiped out by an unidentified force. Suspecting that the entity Licht may hold the key to understanding the town's fate, Jail becomes determined to seek answers from him.

A mysterious and powerful entity known as the Demon of the Abyss emerges, posing an unknown threat. With no one else understanding its nature or how to fight it, Licht steps forward to take control and lead the effort.

Licht reveals his full power, transforming into a nearly unstoppable force of destruction. His immense strength, however, appears to carry significant consequences.

Licht and Mizuka revert to their original forms, but the group's female members face the lingering effects of their unresolved Star Stake. Meanwhile, Jail is summoned by the military's supreme commander.

Jail, Lynn, Pele, and Hina are transported 300 years into the past by Nana and find themselves in a mysterious facility with advanced technology. There, they encounter Rihito, a young man Hina believes to be Licht.

The time travelers assume the identities of students at a military academy, adapting to their new environment. As Schmerman outlines the academy's strict "rules," the group begins to realize the institution's true nature is far more rigid and ominous than it initially appeared.

A student is caught peeping into the girls' bathhouse, prompting an investigation by the class to uncover their identity. At the same time, Jail tries to learn more about the current timeline and the reason behind Nana's decision to send them there.

Jail uncovers further secrets with Nana's help but is stopped by Alan during an escape attempt. At the same time, Class A students move closer to achieving their goal of creating a non-lethal military force.

Rihito chooses to undergo a procedure that will transform him into an Ace, a pivotal event that time travelers have long sought to alter. Now aware of the consequences, the travelers find themselves divided on whether changing the outcome would truly benefit everyone.

Rihito gains immense new powers and appears poised to easily overcome his adversaries. However, the enemy—composed of skilled and resolute soldiers—proves to be a formidable challenge, refusing to surrender without a strong fight.

Returning to their original time, the characters discover the actual history of their world. Frustrated that their attempts to alter the past failed, they resolve to focus on fixing the present and guiding the future.

Nana hosts a celebratory gathering for the exhausted time travelers following their arduous journey through different eras. The group gradually begins to heal and find solace after experiencing the emotional toll of their historical encounters.

Hina stops Licht just before he leaves on another journey, following Nana's party. Meanwhile, Alex considers his next steps as Schmerman's Special Service Unit continues its enigmatic operations.

Licht leaves the group and confronts Doan, who easily overpowers him. The others pursue Licht, while Jail seeks resolution by visiting his adopted father.

Licht's death prompts Doan to realize that others are also working to eliminate Alcia, leading him to resolve to kill them all.

Licht, having seemingly died before, returns to life and attempts to rescue the others from Doan. Meanwhile, Mizuka sides with Doan, forcing Licht to confront both Aces simultaneously.

After Mizuka is incapacitated, Doan becomes Licht's primary rival and captures her in an inescapable gravity prison. Despite this, Hina continues to have faith in Licht's abilities.
