Ahhh… Usamaru Furuya’s No Longer Human. Great stuff!
But the previous tags are a little wrong about this series. It’s not really horror manga. This is a drama.
Vols 1-3 are still available thru Amazon and Right Stuf!
One of my Favorite series! Sadly I only bought volume one the day of release and haven’t got 2-6… But it is very good! :D
