Bitch in Sheep's Clothing: Ginei presents himself as a handsome gentlemen (bringing Moka, Kurumu and Nekonome bouquets of roses as a welcome gift), when really he's nothing but a pervert who routinely spies on girls and then frames Tsukune for his own crimes so that he could have Moka and Kurumu to himself.
Frame-Up: Ginei frames Tsukune for his various crimes, Kurumu and Yukari managing to clear his name with their own internal investigation and printed fliers.
I Never Said It Was Poison: When Ginei mentions that Tsukune moved a drum to the window sill to get a better look at the girl's changing room, it is pointed out that there is no drum in the photograph he is referring to and there never was a drum before or after the supposed crime, thus Ginei would have had to be there to know about it. It doesn't take very long for him alibi to fall apart, as he first claims that he had never been to that location before the story broke, then he says that he had been there before knowing that there was no drum before.
When Ginei twists the situation and says that Tsukune was looking up Moka and Kurumu's skirts, Tsukune admits that he did actually see their underwear. The fact that he saw it by accident when he caught Ginei doing it intentionally ends up getting lost in the moment.
Right after Kurumu and Yukari reveals all of the evidence they have to confirm that Ginei is the real peeper and not Tsukune, dozens of polaroid photographs of girls in varying states of undress spill out from Ginei's coat, further incriminating him.
The first time Tsukune is framed by Ginei is when he catches him looking up Kurumu and Moka's skirts, Ginei casually twisting things so that it was only Tsukune who did it.
The second time was an accident, as a pair of girls hear Ginei freaking out at the idea of Tsukune and Moka being as second base and the girls find Tsukune walking by the window and assume he was peeping on them.
Nazo: Wrong place, wrong time, wree.
The third time has Ginei trick Tsukune into looking into the girl's locker room and then photographs him doing it.
The Peeping Tom: Ginei is a routine peeper, watching girls in various states of undress through windows and when they aren't looking. When Tsukune catches him looking up Moka and Kurumu's skirts, Ginei frames him for it.
Right for the Wrong Reasons: When the story of Tsukune being the alleged peeper becomes public knowledge, Kurumu is convinced of his innocence because she finds the idea of Tsukune leering at anyone other than her to be absurd.
Silent Treatment: Moka breaks it off with Tsukune when she thinks he was peeping up her skirt, telling him that she doesn't want to be around him anymore when really she just wants to temporarily dog-house him as a punishment.
