Diary from Another World: I Picked up a Dragon in the Village

An ordinary high school student accidentally picked up a dragon that could distort space in the village. We were targeted by evil gangs. With the help of dragons, we opened up another world, an unknown world. In this new world, I continue to develop, fight monsters and upgrade, hoard equipment, and travel around the new world with my brother-like dragon. But~·But, can I go back to the original world? ? Or will you stay forever in another world and live with dragons? ?
