The provided chapters detail the protagonist's tumultuous life and his eventual transmigration to a new world. Initially, the protagonist recounts his harsh upbringing as an orphan in the slums of the divine nation of Zilforia, where survival necessitated violence and theft. His life took a turn when he was adopted by the first commander of the mercenary unit "Silver Cluster," a man who championed the ideal of ending war. This commander raised the protagonist, teaching him discipline and humanity, transforming him from a "monster" into a person.
During his time leading the Silver Cluster, which later became Zilforia's direct knightly order, the nation's expansionist policies under the guise of spreading the teachings of the goddess Phonia led to constant warfare. The protagonist, though conflicted by the divergence from the original ideal of ending war, participated in these conflicts, becoming a national hero but feeling an inner emptiness. His life with the Silver Cluster ended around his sixtieth year when the unit split. A faction, the "New Silver Cluster," declared war on Zilforia, advocating for the original ideal. This internal conflict resulted in the mutual destruction of both factions' leaderships, and the remaining Silver Cluster members were absorbed into Zilforia's regular army. The protagonist, away on a distant campaign, learned of this aftermath only later.
The protagonist discovered that a significant portion of the New Silver Cluster was his own kin, leading to their execution and his family's exile. He learned that Zilforia's ruling elite had orchestrated the Silver Cluster's downfall out of fear of its growing power, a betrayal that revealed the depths of human depravity to him.
Ten years later, in the year 1069 of the Dear Era, Zilforia, weakened by internal power struggles after losing the Silver Cluster, faced a united assault from three rival nations: the Empire Imperio, the Magedom Magia-Aegis, and the Demi-human Alliance Deminista. The protagonist, now over seventy and living in seclusion as a shepherd, was drawn back into conflict by an old friend's plea for help.
He found himself in a desperate battle against Imperio's General Massey Kanui and his elite guard. Severely wounded, with missing limbs and multiple fractures, the protagonist, despite his physical state and depleted healing magic, fought with the "Unbreakable Sword" and "Light Armor." He managed to defeat Massey and his forces in a brutal, bloody confrontation within a ruined church, a testament to his past as a fearsome warrior. He killed Massey, who questioned his loyalty to a nation that had betrayed him. The protagonist, however, revealed his motivation: to prevent the indiscriminate slaughter of Zilforia's innocent civilians by Imperio's supremacist ideology, even if he no longer cared for the nation itself.
After the battle, bleeding out and expecting death, the protagonist found himself washed ashore on a beach, inexplicably alive and in a young woman's body. He discovered he had regained his full physical health, including his lost eye and limbs. This new body, with its tanned skin, silver hair, and voluptuous figure, belonged to a young woman in a world that seemed technologically advanced, featuring "iron birds" and "iron cows." He realized he had been reincarnated into a world called "Reva," a civilization he had studied in ancient texts.
He encountered a young girl named Noriko, who, despite her initial shock at his appearance, offered him clothes and shelter. Noriko was preparing for an audition to become a "Vtuber," a virtual YouTuber. The protagonist, now calling himself "Lulu," was intrigued by this concept and the world of Reva. He learned that Reva was a peaceful, technologically advanced society, a stark contrast to his past.
Lulu's journey led him to meet Noriko's mother, who worked for an apparel company, and her brother, Asakura Susumu, who wrote a popular manga titled "Zilforia Chronicle." Lulu recognized the manga as a historically accurate, albeit slightly altered, account of his past life in Zilforia. He discovered that Susumu was a fellow reincarnator from his world, and the manga was his way of preserving the memory of their fallen comrades.
Lulu was offered a position as a Vtuber by Susumu's sister, Asakura Akari, the president of Ya-Ta Production, a Vtuber agency. Akari, impressed by Lulu's potential and his connection to Susumu, offered him a contract that included living expenses and the opportunity to pursue his own interests. Lulu accepted, seeing it as a chance to adapt to this new world and potentially find answers about his transmigration. He also learned that Susumu, a former vice-commander of the Silver Cluster, had been living as a manga artist, and Akari was a retired Vtuber. The narrative concludes with Lulu preparing to embark on his new life as an idol Vtuber, a stark contrast to his past as a warrior.
