Izuku had recently moved into his own apartment after turning 24, and along with that he adopted a dog. A cute Shiba Inu who had on a green and white collar that matched Izuku's hero costume, due to him being a Pro Hero/teacher at UA, he found his merchandise in dog accessories like a collar and leash. He had decided to bring his dog to a dog park one day to let his dog get some exercise and outside time with other dogs to play with.
