Lavi has such terrible luck with women. Eliade tried to feed him to carnivorous plants, Lulubell turned out to be a Noah plotting everyone's demise, Chomesuke/Sachiko was killed with no hope of redeeming her soul, and of course, Lenalee is WAY OFF LIMITS. It's a good thing he has friends to make sure his stupidity doesn't get him killed.
I think my favorite part of this comic is actually Allen's face in the 4th panel.
…Is this one of those 'three strikes and you're out' type deals?
