Only you can support Semen Demons.
Yen Press seems to have corrected their initial blunder in releasing Kakegurui only Digitally.
Coming up: Paper releases
Vol1: 18. Juli 2017
Vol2: 19. September 2017
Vol3: 14. November 2017
Vol3 contains up to chapter 16. Only 26 chapters not in English paper volumes left.
(On second thought: They only now get the value of Semen Demons gambling? Disgusting.)
