I for one find the genderswap phenomenon of Suzumiya Haruhi to be very amusing. So here’s some nice fanmade videos (actually audio would be a better term since only the sound matters) of various genderswapped image songs of the characters.
Kentai Life Returns! (Kyonko version)
Hare Hare Yukai (Kyonko version. She sounds so cute)
Maggare Spectacle (Itsuko version. She sounds hot)
Various image songs (Haruki, Yuuki, Mitsuru, Tsuruya, Ryou)
Girl Comp Society Prez singing Tsuruya’s image song
