Taniguchi is comically lecherous; he gives a 'score' of attractiveness to each first-year girl based upon his tastes and preferences. He remembers the full names of everyone receiving an 'A' rank, with Ryoko Asakura receiving an AA+ and Yuki Nagato receiving an A-, in the manga he also ranks Haruhi Suzumiya as A+. Taniguchi however remains unable to get any of these girls (he is implied to be the one who went out with Haruhi for the shortest amount of time she has ever dated: five minutes). As for Mikuru, her mere presence elicits an altered state of adoration for Taniguchi.
In The Sigh he attempts to hook up Kyon with Haruhi, by shooting down Kyon's first two choices of Mikuru and Yuki.
When Yuki Nagato alters the world, he loses this date, an event that is unexplained but is implied to occur because Kouyouen had to be changed for Yuki's whims. This lack of plans for Christmas Eve is the first strange thing Kyon notices about the new world. Aside from suffering from a inexplicable cold, Taniguchi's personality remains intact in the new world, and because Yuki was unable to alter anything beyond one year before, he still remembers Haruhi, and indirectly helps Kyon find her. When Yuki turns the world back to normal, Taniguchi regains his date and good health.
In The Intrigues of Haruhi Suzumiya, Taniguchi is "dumped" by his date, who tells him she "made a mistake". He let her keep his watch. (She was later revealed to be Kuyou Suou.) After the breakup Taniguchi falls into a state of depression. He tells Kyon that he envies him (because he believes Kyon is dating Haruhi).
In The Surprise he had a chance encounter with Kuyou. She tried to return his watch but he refused. Afterward he told Kyon a little about their relationship. Kuyou later told Kyon she had mistaken Taniguchi for him, and broke up with him when she realized her mistake.
The Disappearance of Nagato Yuki-chanEdit
In The Disappearance of Nagato Yuki-chan, Taniguchi injured himself while trying (and failing) to impress the girls at Kouyouen. Kuyou Suou noticed him and dragged him to the infirmary. Afterward they began dating.
