This anime is particulary fun to watch for everyone who are not afraid of vulgar humour and parody. Two main protagonists travel around a weird world of various anime styles and genres like mecha, shoujo, adventure and etc. I disliked this anime probably because of lots of vulgar humour which is not very appropriate for me, but it was really fun to watch at times, and the complicated backround story was quite interesting. I recommend this anime for people, who have tasted a lot of different anime genres, because this anime allows you to see most of anime genres from an amusing perspective.
