Wow i didn't know. I'll trry :)
I didn't either until I suddenly found the "manga" section on Crunchyroll's website x) They even have an app called "Manga" (at least for Android, I don't have iPhone so I don't know) I've had CR Premium since 2013
I've also had CR premium for a while and I knew they had the manga section, but it never had anything that interested me, so I don't usually check it lol you made me a huge favor with your comment!
I just finished reading ch. 63 and DAMN, this manga is so good ;___; I want to know if they update on a monthly basis or what though.
I've waited since June/July for chapter 63. I found it when they had chapters from 53 to 62 (I think that was in June or early July). Chapter 63 came out this week (?). So I don't think this is a monthly thing. But I have the option to actually support a manga I really like (I do with other mangas too, but they're usually very expensive to buy in physical form here in Norway).
Just a note. If you have Crunchyroll Premium Membership, you can read this manga _legally_ from chapter 53 until 63 ... Just saying. It's just $ 6,95 a month.
