The series, begins hanging lampshades and parodying a variety of anime and manga tropes and with a barely simplistic artstyle, but since the very begining the plot and characters hooked me up. After some chapters, a lot of suspense is created and the story begins to unfold, it sudenly becomes deep and with twists that are almost impossible to see coming (but there is a lot of foreshadowing for them), the motives of the characters are revealed and you can see the author carefully constructed their psichology, and there are a lot of crowning moments of awesome. In a nutshell, don't let the apparent sillyness fool you, it becomes better than a lot of proffesional mangas (and gets a lot of art evolution), while maintaing a lot of humor.
As for the comedy, the jokes are funny most of the time, altough some may become confused since the humor sometimes can get really Spanish, the humor has been described as "american like humor" by readers though. There is some toilet humor but if it bothers you don't worry, is not that much.
As for now, it is only in spanish but if you can understand it, give it a shot, it is awesome: http://jesulink.com/descargas.php?sub=cincoelementos
