S01E40: The 3-Door Test

The girls go to take the Level 3 Exam, hoping to pass so they can be granted each a seedling that eventually sprouts into a tree and yields an endless supply of magic spheres. Surprisingly, the exam is one they will have to take separately. They each must pass through a door into their own world to encounter a series of events that will test their own individual strengths and are only allowed to use magic twice. The girls also must also complete the exam in one hour or else they will fail.
