The MAKAI is in crisis, and two demon girls—Eldied and Diana—have set out to reach and defeat the source of it. The path is a danmaku shooter with a Rank System: more aggressive play builds power faster. Shooting enemies, grazing bullets, and maintaining active pressure all feed into a cumulative power meter that determines what attacks are available. Use accumulated power to maintain a strong sustained shot, or spend it on buster attacks that clear bullets and enemies simultaneously. How you play determines what you have access to when it matters most.
