The Professor said that Yuzu was the fourth piece he was searching for. Four Dimensions, so four Yuzus: Yuzu (Standard) Ruri(Xyz) ?(Synchro) ?(Fusion)

If Yuzu is the last piece the Professor requires then, possibly, the other three girls are already at the Academia. In episode 38, we see Ruri within the facility (due to this many people are assuming that she is Fusion Yuzu. But I hope she is Ruri.) There are so many possibilites and reason to why Ruri is working within the Academia - as listed in the above comment. In the end, we still don't know what the Professor plans on doing with these 'four pieces'. Maybe, he plans on using all the Yuzus from each dimension as recurits in his army or it has something to do with their bracelets. I'm sure that each girl (excluding Fusion Yuzu) would refuse to assist in such ambition. In this case, the Professor may have used the mehtods that was listed above to bring the girls to his side. Ruri and Synchro Yuzu may have unwillingly joined - by whatever method the Professor used. Fusion Yuzu, on the other hand, is already from the Fusion dimension and so she should be like Yuri, an evil counterpart of Yuzu.

If Ruri really is a spy for the Resisitance or was forced into joining against her will with all her memoreies still with her, then it brings up a point regarding the Slifer Red Jacket she wears (this can also prove that she is Ruri, not Fusion Yuzu):

-She is weak in using Fusion Summoning

-Due to her being from the Xyz dimension, she was put in a low rank (similarly to Jaden)

-Yuto stated that Ruri would never learn Fusion with a smile on her face. Possibly, Ruri deliberately fails her Fusion classes due to her anger and hatred towards them.

Another point I like to make, Fusion Yuzu should be able to use Fusion very well - better than Yuzu (maybe even Sora). If so, then she should be wearing the Obelisk Blue Jacket - Not Slifer Red! Or Maybe Fusion Yuzu is not a student in the academia, like Yuri, she could be an army captin or leader.

I think that the girl in the Red jacket is Ruri Kurosaki!
