What started as just school issues quickly turned serious this episode; what a turnaround. But let's be honest, we'll eventually get to that point, considering the overall atmosphere of this anime, yet it may shock a lot of viewers unaware of the direction the plot is heading into. Curiously enough, resolving this mystery opens up another; I guess that's how we are going to do this moving ahead. It does a really good job at sustaining audience curiosity on this overtly complex plot.
