Cheerful Wonderland

"I'll turn your school into a paradise!"

Chia transfers to Hanamori Academy, a prestigious school with a very strict culture. The rigid school rules make everyone feel suffocated. Fortunately, Chia is a "beautiful revolutionary" who has come to save Hanamori Academy! She transfers to problematic schools and has a mission to make everyone happy by starting a "fun revolution". Together with her partner, a teddy bear named "Funny-chan", she steadily reforms the school by changing the uniforms to cute ones and making the lunches buffet-style. However, she ends up angering the scary principal...!?
