Parallel is a wonderful short manga that has served its purpose to me, and that was to act as a short pause in between longer running series. It was the right kind of length and not complicated at all to confuse or irritate. The only seriously noticeable flaw about this manga is that it has a last chapter that is completely out of place. The chapter itself is good, but it’s just out of place because the events portrayed in it take place before the story ends at chapter 19.
