Tsuyoi Tori High School - The Royal Crystal

It's almost winter break during Kristin's junior year! This year means that Karla and most of the gang will be graduating, and the graduates from the previous year including Ivan, Rameses and Gilbert will be returning for break!

What mystery and adventure will unfold when Kristin decides to wander into the school boiler beneath the school building and accidentally discovers an even deeper secret? Literally. She finds an extraordinary crystal that not even the police or Anna can place their finger on.

Following the discovery, a few of the gang members start to get weird ghosts appearing in their sleep. But the even more mysterious thing is, that they know about the crystal. In fact, more people know about the crystal than they realize. But who are the ghosts? And who is the person watching this journey to the past? A very spellbound past...
