It's really weird when the series does this. It just cuts away from the main story to focus on completely different story that barely connects. It's the same feeling I got from Roba in the first couple of volumes. Like the story established a connection between the MC and Roba, but they never found out that they both had powers, and Roba just died (presumably, unless he pops back up later, I hope not). So my question is what does this have to do with anything?
