The Strongest Hero from Another World Becomes Gojo's Pet Dog

After my father retired, I became the world's number one hero. But one day, while playing a ball game with Dad, he got so caught up in it that he forgot to hold back his strength and hit me out of the atmosphere. Maybe I crossed the atmosphere too quickly, because I even opened the door to another world. And so I transmigrated to another world and became... a dog. So what if I'm a dog? I can still be a hero... right? Before I could get around to fighting for justice, a silver-haired man I had never seen before picked me up and took me home. At first, I was afraid I'd scare him, so I pretended to be a real dog. But then he pan-fried steak for me, roasted pork ribs, and fried chicken legs. He even dressed me in little LV outfits and put a Gucci leash on me. Being a dog is the best! Don't try to take this from me. I'm a dog! The world's strongest hero dog!
