A pretty cool read is Hakkenden The Eight Dogs of War, or [switch]/switch Dragonfruit. I also like Adekan. (each of these is multi-chaptered and have interesting plots.
Hi, I'm having a rough time right now and I would like some manga's that cheer you up. I'd like a long series and it would be awesome if it isn't a very popular one. It doesn't have to be completed. Thanks :)
