Peter Grill and the Philosopher's Time manga volume 13 features story and art by Daisuke Hiyama.

Peter is currently in Ogrestan, land of the ogres, where his status as the World's Strongest Man inspired the lust of Queen Nina Alpacas and heaps of ogre ladies all across the country. In the name of reaching enlightenment, he soon visits an ascetic training center, only to be surprised to find an old childhood friend there waiting for him. Will Peter ascend the path to enlightenment, or succumb to the delights of the flesh?
