Desu Kawaii Land of The Senpais is a country taking up the space that was previously Japan. It is ruled by Dubious. Currently the island is surrounded by HUGE WALL that happens to be a popular tourist area to only the Kawaii Land residents. Anyone who happens to be an outsider and lays eyes on the wall will be destroyed instantly. 

The Senpais take their shit seriously and is a super serious country that despises all outsiders.
