I have to admit that I only managed to read the first five chapters and then skipped to the last one. I found it to be so boring, weird and ultimately annoying, that I couldn't keep reeding it all. Totally not a manga for me. There are some funny parts here. But they are usually so out of context that they don't help.
Fantastic! The main character didn't get me bored at all! It kept my heart racing and is a very cool manga that didn't have too much blood shed (at least in my opinion, cuz the deaths or injuries were dealt with right away anyway) A gem! :)
