After following this particular series, I overall enjoyed it. The fan service was fan service. At the beginning it was very slow, but soon it began to form a plot, which I liked the idea it had. The ending wasn't as climatic as I expected but hey you can't argue with the whole world having good luck. Especially if Rio is responsible for world peace. I will say that I do look forward the next season. Mysterious man with a cape and red eyes with some little girl that has a bone to pick with someone. I would recommend this to anyone who just wantsa feel good easy anime to watch to pass the time by.
