Dr. Stone and Astra: Lost in Space are two Shonen Jump series where our main characters are thrown out of their usual environment and end up stuck trying to survive in new circumstances, whether it be a return to the stone age or outer space. There's a lot of scientific thought processes that the characters think about when it comes to the new environments they explore and the ways they try to survive, and it can be surprisingly really emotional at times. You'll learn to love the characters and be intrigued by the new world(s).
