Yousei Daisensou: Touhou Sangetsusei

The 12.8th game in the Touhou Project, which focuses on freezing bullets rather than dodging them. In the previous winter, the Three Fairies of Light wanted to gather other fairies to cooperate with each other. They decided that the only way to do so was with force, so they destroyed Cirno's house. Cirno mistook this as a declaration of war.
