Imagine a world full of flying dragons, talking mushrooms, burning forests, supernatural bisons and many more strange creatures… Well, Mondo, Rokuna, and Dr. Hiiragi go on some crazy adventures taking on lions and crazy monsters in hopes of creating a passageway between worlds so humans and monsters can live together.

One day, Daisuke Kadota, also known as Daisuke, learns of the existence of Moncolle by chance. Around the same time, he learns that Saki Hanazono, a classmate he is interested in, is a Moncolle player, and tries to make her look good by saying that she is good at Moncolle, so she ends up actually starting to play Moncolle.
