just sharing this from tozica's patreon seems tozica is planing on finishing soon
"[IMPORTANT] Patreon site will be closed.
Thank you for your supports.
I will close this site at the end of this month.
So please stop your support on Patreon in this month.
All updates in this month are already done.
I answer to question which you may raise as follows:
Q. Why do I close Patreon site?
A. To say shortly, that is because my activities in Patreon have become burdens rather than helps for me. System of Patreon different from Fantia and Ci-en in various points and those differences have been taking more workload on me. So I decided to close this site in order to make my activity more comfort for me.
Specially, the next dungeon in KANADE-ROGUE will be the last dungeon and will be available for free."
