Arad Senki: Slap Up Party

A group of friends going on an adventure across the continent/world, in order to find/save something or somebody, is the premise. Comedy is always present as well as some good shounen battles. I would say Slayers is a lot better than Arad Senki in all matters, in the script, in the animation, in the soundtracks, etc., so if you saw first Arad Senki, I guess Slayers would be a nice surprise.

Well, both animes follow the adventures of a group of children, mainly girls, around their city, exploring and enjoying their lives all along the way. Very nice and relax to watch.

Well, the name says almost everything, is about the daily lives of the characters. Both anime have random sense comedy so, for those who like comedy, this is it.

Both have the same kind of world, the same kind of enemy, the same atmosphere. The purpose of one is similar to the other.
