Touhou 5

Touhou 5: Mystic Square is a vertical-scrolling shoot-'em-up released in 1998 for the PC-98 by Amusement Makers. It follows Reimu Hakurei and others as they journey into Makai to uncover why so many demons are entering Gensokyo. The game refined the series' core bullet hell mechanics and served as the final Touhou title for the PC-98 era, paving the way for the modern Windows games.
