Bakemonogatari: Monster Tale

There's pretty elaborate wordplay in this one. In fact, it’s so well thought out I can only assume it’s canon, so beware of potential spoilers. Araragi is worried over his sisters having boyfriends he hasn’t met, so he insists that he’s introduced to him. With no other choice, the Fire Sisters agree to bring their boyfriends on the next day, but they’ll bring two people he wasn’t expecting. -YQII
