My theory about the "GHOST" is that there are 2 types of ghost which are:
1. The ghost with a school uniform in Magic Island.
2. The ghost in white dress which is in the practice room.
We have two entities that we don't have much more information to them but I believe that the ghost with school uniform is the bad one while the other which is the ghost in white dress is the good one. I don't have evidence that support my theory but the ghost seems to be the guardian or she want to help Soobin and Hyuka. And my question is why????Why is it that the setting must be in a practice room? Maybe crossover is still there?
