Murder the Hypotenuse: The Coalition seems to think that if they got rid of Tsukune, they would have a better chance with his Unwanted Harem.
No Guy Wants an Amazon: Downplayed. When the Coalition points out how much of a weakling Tsukune is, it really effects him, feeling guilty that they always have to come in and save him.
Not What It Looks Like: When Yukari sees Tsukune walking off into the forest with a bag, they all assume that he is leaving, when really he was giving a bunch of letters to the bus driver to mail for him.
Stalker Shrine: The Coalition has one with all three girls in it.
