Nitori-chan Dash

Nitori Kawashiro's research and development budget has run out, and the solution she has arrived at is to build speed-enhancing equipment and sell it to the non-flying yokai, slow-moving yokai, and humans who could use it. The prototype is complete. Before bringing it to market, Nitori needs to make sure it actually works—and that if something goes wrong, she will not be buried in complaints. A Touhou fan game structured as a careful pre-market test run.
