So I came across this really cool manga called Re:Monster, and it only had 16 chapters, and I was so sad when I got caught up with it.
Then I found out that it had a light novel and that it was over 300 chapters long, and it's been great. Though I do think that this
story goes better in manga form, especially because the manga is drawn really well and the characters looks badass.
Here's the MAL for the manga: http://myanimelist.net/manga/73271/Re_Monster
