“Is she leaving the group or is she just going…focus on her studies and then rejoin”
I am not sure, but I think she’s leaving for good. If it was for a short time, then did she really have to leave the dorm Fairies live in and the school they go to? She could have stayed with them in the dorm and go to the same school while taking a break from the activities.
She didn’t. She went back to her old school and to her family house in Kumamoto.
Moreover, Vision Factory said that they will delete her blog and twitter.
As you can see, the “official check” is gone.
Also…they removed her from their official page on Vision Factory’s site.
