戦火－IKUSABI－

There is secret demon-hunting organization that dates back to ancient times. Its members - though few in numbers - protect peace of each epoch from the shadows. It's year 1707 now. Peace has come to this land with the establishment of Tokugawa Shogunate. However, suddenly a dangerous shadow monster again threatens the world. His name is Oda Nobunaga.
