Fubuki is one of those manga moms... She has to ensure with theoretical and practical lessons that her daughter knows how to snatch herself a man, keep him pleased and have lots of cute children to perpetuate the family line. I assume Himari's father has likely died from snu-snu some time ago...
There’s something fucked up about wanting to take your daughter’s boy toy and pass him around. On the bright side, rejuvenation shouldn’t replenish the egg supply and lolibaba must be near 70, so no one has to worry about new aunts or uncles.
