for most part the perverted stuff is for jokes, its no way meant to be important or constant or the aim for the rp
and as Leslie said, if you dont want your char to be with those matters we can work around it

for now I can only speak about my chars
Chizuru is more as in, you can do anything you want to her and crap, she is not one to be publicly perverted normally
though her sword may be, but as said its mainly for jokes and punishement, dont think it will be used much if it will be used ever at all

Gaurman has a goal but that is that, nothing will happen with it, at beat he may, if asked, say, he wants a harem of summoned creatures, nothing more

the twins are normal further

so...
off course I dont know how the rest are with that matter, but as said, its not the aim or meant to be constant (or it will become boring anyway, jokes need to be used in moderation)

anyway, with this, you want to know if its constant, the answer is no
the guild is very much just for the sake of living a free live with jobs, having a relaxing guild with jobs you can do if you want and at times have some deeper plots as well ^^
