- Description from Novelupdates

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.
