Attack On Former Hell of Blazing Fires

Something has been going on underneath the surface of Gensokyo... This is causing the residents of the Palace of the Earth Spirits and the people of Ancient City to flee above ground. Utsuho, Rin, and Koishi look for help, while the others left at a makeshift village hope the trio would come back soon... *DISCLAIMER*: Settings and characters are owned by ZUN.
