Hapi Mari
This manga is one in which I have read a couple times but I always felt that it was a bit long like it was extended just for the sake of extending some parts. Don't get me wrong it is a excellent manga and some of the parts are so funny that they make me laugh out loud. Others are really sweet or frustrating. So it is a good read. However, if it had just one flaw it would be it's length.
Blood Lad
I started reading this manga and enjoyed it even though I am not big on comedy. It's good but I think it was written for a bit of a younger crowd than me. After I read some to my son though he loved it and became a fan. I would suggest this to anyone who is into shounen comedy.
Anata no Omocha
Okay... this one. I have read it before. I think there are other oneshots associated with it posted on other sites. However, this one I am not too big on. I tend to get embarrassed just watching or reading some types of comedy and this is one of those types. That girl doing the woogee thing made me want to stop reading but overall if you like that kind of comedy. Then I am sure you will like this.
Kindan no Koi wo Shiyou
I liked these stories better than the other longer story about hisako and her wolf. I think these ones are just the right length. Honestly I started the longer story but stopped because it really didn't make me want to read more. This one is good though.
