I find it rare to see the drama that tells to suggest us to love the earth more. That's why I rated it 9/10. The story is about some student and teachers in a high school accidentally go to the future. This drama should makes us realize to do something for our earth. We can't always talk "go green" but please DO something. I really love how reliable Yuka and Asami as teachers. The minus is the effect for describing the place and monster animation. Those are very poor.
