Honestly a great chapter!!! Retto wasn't afraid to actually do stuff with a girl, even though it was just an illusion, I count that as progress! As he usually chickens out of everything.
Plus the ending was just great with everyone going back to being naked and showing up to save him.
Man, just give me a harem end and I would love this manga. I just don't care for Hoshino, who will obviously win, so at least in a harem the other girls win as well.
