Valkyrie of Phantasm — is a shoot em up set in the skies of Gensokyo at high speeds. A meteorite suddenly fell on Gensokyo, and small droplets of light appeared from the cracks and scattered in all directions. In the end, they fall into the hands of the most powerful people. One of the three fires reached Reimu Hakurei, surrounding her with armor and empowering her as a Valkyrie. Fly freely through the sky dodging myriad projectiles and fire spells! Using the experience we gained from creating Touhou Sky Arena and Magical Battle Arena, we are creating a project with the goal of making aerial combat even more exciting, beautiful and fun.
