This study is about a case of a 5th grade girl who has not experienced stable affection since her
birth and has been exposed to serious mistreatment and noninterference by her family including father
and an elder sister after being abandoned by mother. The case study covers a process of the child who
becomes a girl heroine reinforcing her own self through sandplay in perspective of Campbell’s Hero
Myth. The child’s sandplay therapy process was analyzed by applying Campbell’s Hero Myth and as a
result, the process consisted of three big flows of departure of refusing vocation of a hero but starting
adventures, initiation of overcoming continuous sufferings and surviving and return. The plot

own self and faces death for resurrection with funeral. And then, with introduction of supernatural
supports and helpers, the girl experiences brave activities to save animals in volcano and encounters

decides to return to reality and becomes a girl heroine who returns to the current world. And she
changes to befriend others in her age, to achieve outstanding academic results and to express her own
feeling with bright smiles. It demonstrates that sandplay therapy is effective to a child abandoned since
