His appearance is like a small child with unruly, pale, grey-white hair. He wears his Divine Bell in his hair and a black trimmed vest and shorts with symbols. He almost always has a worried look on his face.
He is a very sweet little boy who listens to others well and wants to help out. He is also very timid and worries about angering others. Sometimes he speaks his mind without realizing and tries to hide. He was worried when he was initially unable to use his powers after being awoken but eventually was able to after choosing No-Woo as his master.
Hoa-Back was awoken at the same time as the other Divine Bells. He had wanted to stay with Gang-Hui, but was told to return to Nan-Hun with the Princess without leaking any information as to why the Divine Bells had been turned back into humans.
As of the latest chapter, his bell was shown to have cracked, possibly signifying his end, along with No-Woo.
His ability as a Divine Bell is to create glowing, white streams of cloth that he can manipulate to attack multiple enemies or defend his Master.
Created by Ga-Bi as one of the eight Divine Bells.
Seems to have a close relationship with his fellow Divine Bell Sun-Hoa.
Becomes attached to No-Woo when he is awoken, and eventually chooses her as his Master. She treats him like a younger brother.
