We have this kind of topic for anime and other things...Why not manga!?
I spent a good amount of time in the wee hours reading manga (If it's possible to read too much manga, I probably do). The one that I remember the most from last night that I really enjoyed was the manga Kaeru no Ossan (or, in English, Old Man Frog) by Zenyuu Shimabukuro. It's a comedy gag manga that's got main characters with animal features- the title character is a frogman with a human body and a frog head, who has difficulties due to his, uh, unique body. There's also a fly-man, a centaur, etc. It focuses on a fifth grader who lives with his mom and the old frog guy, and who acts as the straight-man in all the unusual situations that go about in the story. Despite being really silly...It does hit some adult concepts, though. I'm not sure I'd let a little kid read it. But for me, it's fun.
