I'm surprised this hasn't already popped up for this series... considering the content. So let out all your thoughts on possibilities and frustrations! I mean questions!
One of my own first questions was why our unfortunate hero has never tried to find out information on the parents while Hasabe was around. I mean, he doesn't even know their names, which would definitely make finding the next one a lot easier, or at least see if the names change between each one.
The other thing I've always been interested in, was that Hasabe always reappears, but almost always a different age, traits, and history. It almost feels like instead of Hasabe disappearing, it's Jun that is taken to a slightly alternate reality instead.
