About the valentines event...

Will this be the last chance to get the street choco maid CE? I got 2 copies last time and at this point I'd hate not to mlb it since I think it's a great CE especially on someone like OG nero.

Also what do you do after getting the chocolate CEs from the female servants? I think I still have them from last year all tucked away in my second archive and I still don't know what to do with them now that the rerun's coming up.
