Sakurashin Town, where humans and youkai live side-by-side, is kept peaceful through the actions of the Hiizumi Life Counseling Office. The workers there help to promote peace and harmony between humans and youkai, helping peaceful youkai to integrate into society. They are also tasked to find, catch, and banish youkai intent on harming humans.
There are some, however, who seek to disrupt this peace: humans who discriminate or bear a grudge against youkai, as well as youkai intent to cause trouble for humans. Recently, a banished youkai named Enjin has managed to cross the barrier and return, intent on revenge against the humans who sent him back to the youkai world.
