A unique plot idea could be that Rin's tail has a mind of its own and can communicate with other demonic entities. This would lead to some really interesting situations where Rin has to deal with the advice or demands of his tail.
Another idea is that the tail holds the memories of all of Satan's past battles. As Rin discovers this, he has to learn how to access these memories without being overwhelmed by the dark energy. This could involve a lot of internal struggle for Rin as he tries to use this knowledge for good.
