First and foremost, W.A.2 has virtually no connection to the first W.A. taking place almost 30 years later with completely unrelated characters. That being said, W.A.2 is 10 times better than W.A. The story is about growing up, love, and friendship.
They managed to tell a good, complete story in 13 episodes with minimal fillers and silliness. They make full use of each episode, and spend their time largely on character development. All I can say is WOW!!!! Watch this Anime!!!
