[Synopsis]
A new-sensation modern myth fantasy, depicted centered around Sapporo・Kotoni.

This town, which exists as a matter of course today as well, is now, quietly, about to be swallowed up by a sepia-colored fog.

What the elementary school student Haru encountered were strange adults who call themselves "The Gods of Kotoni".
They proclaim. The town is being eroded by the sweet and beautiful "memories of the past".

"The past was better..." That whisper is stealing away the people's future.

A story of courage and rebirth where the history of the people who continued to walk even while becoming covered in mud, and the "present" where Wi-Fi flies about, intersect.

To all the people who have ever visited Kotoni Hondori.
"Were those days good? Well then, the present is even better, right?!"

[What is the "Resident Participation Learning from the Past Musical"?]
Led by the NPO Concarino, which operates the theater in Kotoni, it is an original play with songs and dancing that they have been creating since 2005.
In the land of Sapporo's Nishi Ward, they continue to create fun and heartwarming stories based on things that really happened in the past.
