We'll slaughter anyone who gets in the way of our lovey-dovey time! The passionate and pure love affair of the most vicious lovebird-assassin couple: the one-woman-army heroine Laila and the former virtuoso mercenary Dan!! Even though they want to do lovey stuff like hold hands, cook homemade meals, and wear matching outfits, it's one failure after another!! And then the hit man pursuing them appears...!? Their relationship is nothing but blood, corpses, and explosions!! (Source: Ichijinsha, translated)
