5600-sai no Furoufushi Influencer Iwaku.

After enduring fifty-six centuries of existence, an immortal woman named Jiyu finds herself utterly weary of her endless life. Seeking a definitive end to her prolonged journey, she willingly surrenders to the government. Once the state officially verifies her extraordinary nature and confirms that she cannot die, her fate takes a sudden and unexpected turn. Rather than remaining under standard governmental custody, she is taken by a shadowy organization known only as "Amon." This enigmatic group places her in confinement, but their intentions extend far beyond simple imprisonment. They issue her a singular, bizarre directive: she must engage with modern human society through social media platforms. Acting as an influencer, Jiyu is compelled to share her perspectives and interact with the public online. However, the true purpose behind this mandate carries apocalyptic weight. The organization intends to use her interactions and responses as the ultimate metric to determine whether humanity deserves to continue existing or if it should be entirely eradicated. Now, burdened with the survival of the species on her shoulders, this ancient being must navigate the complexities of the digital age, offering a five-thousand-year-old perspective on the very civilization whose future hangs in the balance.
