I don't know if this is right but I think the author uploads a new chapter each month it may of changed I'm not to sure tho that's what it was last time I checked.
The author posts few original pages of a new chapter once or twice month on her Pateron page. So to have a complete chapter, it might take few months... Also, not sure how long she's planning to keep going with this project since she already dropped it in the past. I guess it depends on how lucrative it is for her. I hope it's working quite well. I personally subscribed to her Patreon page while praying she never drops it. This is a masterpiece both script and art-wise.
Does anyone know the update schedule of this or if it even has one??
