Kajiya de Hajimeru Isekai Slow Life

Eizo Tanya is a middle-aged, very burned-out, software engineer. One night after working late, he throws himself in front of a speeding truck to save a cat. Although the cat survives, Eizo is not so lucky. In a spark of divine fate, the cat turns out to be a godlike being who offers him a second chance in another world! Should he be a legendary warrior? A noble king? Nope! All Eizo wants is a peaceful life making things for others, and what better way to do that than becoming a blacksmith? He does have one other wish: to live alongside a cute cat. His requests are granted but with a twist—Eizo's blacksmithing skills are so overpowered that they're practically cheat abilities. On top of that, the cat companion he wished for turns out to be a half-tiger girl! With so much commotion in this world, will Eizo be able to forge a quiet new life? (Source: J-Novel Club)
