Well, if you're interested in how 'it ends' with the two after the first season, you will have to go through a bunch of episodes that don't exactly add much to the story already known.As it seems a MUST for every second season, new characters are added, but they don't add anything at all if you ask me. It's all just too random and gives too much of a feeling that this second season is mainly meant to add ecchi-ness (aka pantyshots and the likes) Admitted, the first season was already good for fanservice, but now it's just too obvious.
There's enough fun to be had though, so it's not all bad. It's just that it follows standard patterns and that I don't really like fanservice explosions.
Honestly, if they added another episode to the first season and built it to be a "and they lived happily ever after" type of thing, it would have been fine with me too.
If you don't mind the lack of a good story and just want a couple of laughs you shouldn't be let down here.
