From Eroica With Love Volume 11 (Sep070239)

"Written and illustrated by Yasuko Aoike CMX. When Eroica discovers the owner of a large supermarket chain has purchased a Swiss Abbey and plans to demolish it, he concocts an elaborate hoax to save it. Of course his motives are less than holy; he's learned the abbey is filled with priceless medieval art. And as their always-intertwined fates would have it, Eroica's rival 'Iron Klaus' ends up at the same abbey in pursuit of some hidden microfilm."
