Mahoromatic: Automatic Maiden, Volume 4 (V. 4)

Mahoro's little unsolicited sphere of influence begins to widen as Ryuga makes the decision to live on Earth as a human. Of course that decision stirs the ire of Mahoro's Vesper-appointed guardian Slash, who dukes it out with the canonized combat killer...that is until the eponymous peach of domestic servitude steps in to implore peace out of these petulant posers. And when the fights ebb, the excitement flows: breast enhancements, defusing bombs...and building meaningful relationships that will last an eternity...just like silicon.
