The series is basically a bunch of short stories that are totally unrelated to each other. A lot of plot points never got full reasons for why they're happening, some characters just for Team Up Missions are way underdeveloped, and a lot of plot points are cheaply resolved. It's not worth the time, money, and energy if you don't like random short stories, underdeveloped characters, and underdeveloped scenarios. Even though some are entertaining, it's not worth re-reading. The story is really predictable since it's always the usual cheap stuff. The characters aren't well-rounded either since they are bland archetypes, not full people. Some situations arereally unrealistic, and they're assuming all characters are stupid.
