I enjoyed this one a lot more than I thought I would (still wondering why the spin off is called a spin off if it's part of the story...but whatever). I rarely find anything with this kind of ending that isn't tagged depressing_as_fuck or tragedy.
I fell in love with Tokarev so was kinda sad she was killed, but at the same time wanted to shoot her in the head myself for that lame explanation of the origin of the school. That probably could have been more...I dunno drawn out as well as the supernatural aspect of the story (i.e. the school being there cause of a wish). There was so much that could have been done with that but it didn't happen, which gives it an empty, meaningless feeling when you think about it.
However, despite its flaws, the ending was very fitting for this series and left me wanting more...even though there never will be. TTwTT
