Dimensional Yanderes 2 (Yandere Girls x Dog/Inu Boy reader)

A Neko who traveled to different dimensions, had just destroyed the watch that brought him to those worlds. He left the area and possibly to another dimension for the last time. Soon after, a man who was a brother to one of the scientists who made the watch found the pieces and recreated the watch with a new style, more charges, and possibly new functions. Something happened with experimenting with the watch and an explosion happened killing the scientist. The watch soon found a new owner by an Inu or a dog version of a Neko named (y/n). He will now take on dimensional journey and to get back home to his uncle who has a rare disease. Will he succeed like the Neko who used it before him?
