Margaret is my favorite girl, but not for any reasons one would want to marry her for. Any dumbass who would give up the bombshell villainess, the other bombshell heiress, or the yandere knight for the spunky twintails mascot girl is too stupid to breed, sure, but Mags has her own silly charm. Besides, she just wants to not be a prostitute for lolicons. Give her a job as a gardener or maid when all is said and done.
