Oh my God .. thaank you for recommending this ... so good yet so funny
I wonder if you have any thing more liks that (not always for the horror theme)
I'm glad you liked the series. Some others with similar sense of humour to this for me are:
- Angel Densetsu - about a guy with the heart of angel but face of a devil. Quite an old concept that I have seen some series tried to pull but this one did it best, well a bit over the top dramatic at some points but still very hilarious. The art isn't necessarily the best but after a while it did got better ( http://www.mangago.zone/read-manga/angel_densetsu/ )
- Helck - about a hero who wants to side with the Demon kings. It started off pretty light hearted but got a bit darker and more serious fast. It had some brilliantly hilarious moment, good storyline and most of all good character chemistry ( http://www.mangago.zone/read-manga/helck/ )
If you enjoy the humour and the good writing of this series as much as I did, you should check out Girl that can see it by Pixiv as well ( http://www.mangago.zone/read-manga/girl_that_can_see_it_pixiv/ )
The humour tone there is similar. They have good art and brilliant story line. Just a shame the series wasn't as popular as this one
