Lv9999 no Rettousei: Kaiki Shita Ore wa Josei Saikyou Sekai wo Musou Suru

Ayukawa Haruhito was once humanity’s final and most powerful Explorer. Yet, when he opens his eyes, he discovers that he has been reincarnated into an unfamiliar world governed by a drastically different set of rules. In this new society, only women are permitted to become dungeon Explorers, earning immense wealth and prestige through their endeavors. Men, conversely, are dismissed as fragile beings who require constant protection, entirely excluded from the pursuit of glory. Despite the rigid expectations placed upon his gender, Haruhito refuses to abandon his lifelong ambition. He strives to become an Explorer, enduring relentless bullying and widespread scorn as a hopeless failure among his peers. His life remains at rock bottom until a sudden shift alters everything: alongside his restored memories of his past existence, his former extraordinary abilities begin to awaken. Armed with the overwhelming power he once wielded as humanity's greatest champion, Haruhito’s circumstances change in an instant. No longer bound by the limitations forced upon him, he steps forward to shatter the boundaries of a female-dominated world. The heroic saga of a man rising from the lowest possible tier to reclaim his place as the ultimate strongest is about to begin.
