The adventure genre is about travelling and undertaking an adventure in a certain place or around the world (which may sometimes escalate to the whole universe or even to the other dimensions). In this genre, the main characters don’t usually stay in one place. They venture into several different places, usually with a goal in mind (e.g. searching for treasure, exploring some new place, defeating a heinous villain, or saving the world). Adventure anime are so broad and flexible that these shows can usually stretch to a huge number of episodes as well as overlap with multiple genres, usually with action.
