Japanese mythology tells of youkai, supernatural forces of good or evil that inhabit human beings. Those that can tap this power can cause great changes in the world around them, whether through the good deeds they perform or the bad. Tsubasa, visiting his cousin and fellow youkai, Saori, discovers a plot at her school where the teachers are influenced by evil spirits who plan to demonize the entire student body. With the help of other good youkai, Tsubasa and Saori plan to defeat the teachers and restore peaceful order to the town.
