Isekai Shuugaku Ryokou

A new cross-cultural comedy!

In the middle of their high school trip, a group of boys and girls is suddenly transported to another world. There, they meet a princess who tells them about an old legend claiming that their world will be saved by outsiders. Despite hearing this prophecy, the group remains unfazed. Thanks to their laid-back education, they've had plenty of time to read manga and play video games, so they're already familiar with these kinds of stories. However, one thing does surprise them: the Demon King of this world has already been defeated. What are they supposed to do now? Instead of saving or leading the world, their task is to simply learn something new by interacting with different cultures. A new cross-cultural comedy!
