[Machine Translation] Yuki, a businessman who lost his life saving someone and was reincarnated in another world. When he wakes up, he finds himself as a baby, deep in the mountains in a snowstorm... However, thanks to his "strong body," the only reincarnation benefit given to him by God, he is able to handle the snowy mountains without a hitch. At the age of six, he decides to go on a journey with his beloved dog, Pochi, to become independent. He becomes a helper in the town, but he shows one talent after another, helping an apprentice saint with healing magic, dispelling a large amount of miasma without realizing it, overpowering a criminal group, and so on. He shows his unusual talents one after another. Yuki wants to live a carefree life, but rumors of an out-of-this-world Chimikko circulate in King's Landing. Furthermore, it turns out that Yuki's dog is Fenrir, the king of magical beasts, and that his parents are a great spirit and the legendary XX...? This is an exhilarating fantasy of a different world, where the strongest infant who grew up in the mountains (but he is unaware of it) unfolds!
