At some point Kogarashi is going to reveal a curse or charm that was given to him that turned him into a literal puss magnet. Most of the power is located in his nose.
@Drifter: Actually, after they made a note of how weird it keeps happening ever since he moved in, I'm putting money on some strange "lucky pervert" curse that the Landlady put on the place. You know, since this mysterious Landlady is clearly a troll judging from those games she has.
