Before Ien, a task will arise: to find out who Mayumi really is. The demon will make a difficult decision for himself—to seek help from his mother, hoping that she will be able to answer his questions. However, such actions will only bring more problems. They will run into a little orphan girl who will cling to the heroes out of sheer boredom. Mayumi’s kindness won’t let her get rid of the poor thing by handing her to someone else—which later will play a very cruel trick on Ien’s fate.
