Still, of all the things, he believes some silly rumours that the girls started even though he KNOWS all she does is help with gacha pulls? Eh, well, I guess the plot needs to move forward somehow.

Eh, they may have lost their goddess of luck, but hey, he got himself a lover(?) so I'd say it balances out...At least for him, anyway. And hey, even if she can't pull any SSR females anymore due to losing her virginity...Does that mean she can still pull SSR male characters?
