"Yoo-hoo! I'm here to hang out with you!"
Yui Narumi

Yui Narumi, originally known as Yui Kobayakawa, is a character in the Lucky Star series. She is the older sister of Yutaka Kobayakawa and the cousin of Konata Izumi.


"Homework, huh? Eh, as long as ya keep it vague, put down whatever you want!"
Yui NarumiYui's physique is average. She has a well-rounded face, a large forehead, a catlike smile similar to Konata's and straight and short dark emerald hair. She also wears small glasses.


Yui Narumi is Konata Izumi's cousin and Yutaka Kobayakawa's older sister. She is a very easy going female police officer for the Saitama Prefectural Police Department who acts before thinking. She is a bit of a klutz and is a meganekko. However, she has a tendency to exhibit road rage when she is behind the wheel (but, incidentally, shows incredible skill, as a street racer). This is ironic because she is very carefree when driving and breaks a lot of traffic laws, however she herself is a Traffic Officer. She isn't into fashion that much, and after getting married, Yui left behind her maiden name, Kobayakawa. However, her husband is out of town most of the time during the series, so she frequently visits Konata's house, mainly as a distraction, seeking to play her video games and read her manga. Usually, Yui will come over to Konata's home very late at night while drunk. A running gag in the series is that Nanako Kuroi is oblivious to the fact that Yui is married. She drives a blue Subaru Vivio in the anime.
