I think full life imprisonment lasts 40 years, you can get sentenced twice as much (dunno for what reason), Zebra getting 100x means he's just that bad. About the gourmet laws, one's drugs, one should be about wasting food (since they're usually shown eating up everything), one about eating to the point of making things extinct, dunno about the rest. Any thoughts?
P.S: After actually reading the chapter, I knew there can be no"real" sexy females in this manga
