This was a manga that was always meant to be a short two volume read, and I think that kept everything on track as the story progressed. The characters were interesting. Their predicament played out in a way that wasn't too fast or too slow with the exception of one plot point that felt a bit out of left field. It was an engaging read and I looked forward to each new chapter. I also enjoyed the ending. A part of me kind of wishes it had one more chapter to clean up some of the little hiccups but the hiccups weren't a deterrant. Ifyou're looking for a quick read that's pretty interesting and worth being its own short anime or movie, then you might enjoy this story. If you're not into time travel and scifi then you might enjoy it.
