Nina, Zero, and Ichii are back! This time for the Advanced Magic test! The object of the test is-yet again-a crystal drop that looks like candy! When Nina accidentally swallows it (again!), it's up to Zero and Ichii to protect her until it comes out. The only trouble is, all the past participants are back, and only little fragments of the crystal drop will come out of Nina at a time!
