Touma Inaba, a high school graduate, is trying to get into the prestigious Keio University. At the entrance exams, he meets the beautiful Mieko Yotsuba who manages to go into Keio while he fails his entrance exams.He decides to lie to Mieko and says that he passed. As if that wasn't enough, his cute cousin Urara Kasuga shows up because she is in love with him and ends up living with him.
This series offers examples of:
- Attempted Rape: Due to some confusion on Touma's part (which was mostly a product of Urara sending him mixed signals up until this point), he unintentionally tries to rape Urara after a game of strip rock-paper-scissors. He manages to snap out of it before anything unfortunate occurs, however, and Touma and Urara, after an awkward interim, make peace with each other a day later.
- Barbie Doll Anatomy: Averted. There are more than enough scenes of realistically-detailed tits-and-ass to go around.
- Betty and Veronica: Urara is the Betty and Mieko is the Veronica.
- Bleached Underpants: The original manga was Porn with Plot. The anime removes all the x-rated stuff.
- Fiery Redhead: Urara.
- Girlish Pigtails: Komi.
- Kissing Cousins: You wish, Urara.
- Joshikousei: Urara and Komi.
- Love Triangle: Urara loves Touma who loves Mieko whose feelings for Touma may vary.
- Naked Apron: Urara tries this on Touma.
- Rōnin: Touma.
- Silence, You Fool!: Komi says this to Touma in the dub:Touma: Don't take that tone of voice with me.Komi: Silence, loser!
