In a world where cruelty reigns and only the ruthless survive, Arthur—a boy born in the gutters of a city ruled by monsters—knows only one truth: power decides fate. Shackled by the past, driven by vengeance, and desperate to carve his own path, he plunges into a brutal struggle for dominance. But as blood stains his hands and the lines between man and beast blur, Arthur stumbles upon something far more dangerous than war—fragments of a life he was never meant to have. A name. A home. A reason to fight beyond survival.But is survival enough, or will he become the very thing he swore to destroy?

High schooler Shinozaki Yuuta was just your average Japanese teen: addicted to absurdly overpowered mobile games, dodging homework, and secretly hiding a stash of very questionable dating sims. But one fateful afternoon, while grinding an infinite-wave mage survival game and crossing the street at the same time (bad combo), Yuuta meets his doom via Tokyo’s most notorious killer: Truck-kun.Next thing he knows, he’s been reincarnated... as a frog.Not just any frog—a pathetic, squishy, level-one mage frog, plopped into a terrifying world swarming with endless monsters. But the rules of the game he was playing are applyed: each time he levels up, he gets to choose one out of three magic spells, and if he picks the same spell eight times... it evolves into something absurdly, comically overpowered.After dying once, Yuuta respawns in a mysterious black space where coins droped by the killed monsters becomes a currency, where he can buy powerful frog evolutions and ancient magical artifacts. Driven by pure confidence of his ability to respawn and a desire to avoid ever dying again, Yuuta goes on a rampage, fighting monsters like a maniac until he becomes an unstoppable, world-ending, spell-flinging frog king.Bored out of his mind centuries later, he receives a strange message:> A summoner is calling. Will you accept?Curious—and desperate for entertainment—he says yes.Now summoned into a world of beast tamers and summoners, Yuuta finds himself contracted to a weak bullied boy who dreams of revenge to those who bullied him and build a harem. But Yuuta, robbed of his humanity (and a certain important organ), has no intention of helping his summoner chase girls or vengeance. What follows is a chaotic, comedy-packed adventure full of misunderstandings, magical mayhem, and the slow, reluctant bond between a horny thirsty frog (who wants to turn back into a human) and a revenge- harem obsessed kid.Magic. Monsters. Madness. Waifus. And one very pissed-off frog for not having his manhood.

“Failed writer. Failed hunter. Failed at life.”Aiden Jus had heard it all before. At twenty-eight, he was a walking reminder of what happened when you failed your mana awakening and spent thirteen years chasing a dream that would never come true. No powers. No future. Just a cramped flat in the UK and a lifetime of rejection letters from publishers who never bothered to read past the first page.But the day Aiden decided to give up on writing—the day he was ready to finally accept a soul-crushing desk job at an editing firm—everything changed.*[You have been chosen by Nabu, God of Literacy and Scribes]**[Skill Acquired: Narrative Embodiment (Divine-Rank)]*The ancient Mesopotamian deity offered Aiden something unprecedented: the power to physically enter any story he writes and gain real abilities from the fictional worlds he creates.*[You have mastered Celestial Blade Art - Skill permanently acquired]**[You have learned Tier-9 Spell: Void Severance - Spell permanently acquired]*Every sword technique mastered, every spell learned, every power gained inside his stories becomes permanently his in the real world. But so does every death trap, overpowered villain, and narrative cruelty he carelessly wrote in moments of frustration.Suddenly, Aiden isn't just a failed writer anymore. While other awakened humans rely on mana cores and dungeon raids, Aiden's strength comes from the worlds born from his imagination—a power that operates outside the traditional hunter system entirely.As rival gods compete for powerful human contractors and ancient ruins promise unimaginable treasures, Aiden must survive the deadly fictional universes he created while building his reputation in a society that once dismissed him as worthless.**From the typewriter to the battlefield, Aiden Jus will prove that the pen truly is mightier than the sword—as long as you're willing to live through every word you write.**
