Likes and Dislikes

It is revealed in Hiyori's notes that Yutaka enjoys the internet (a remark states: "'s like her toy"). In the same manner it is reveals that Yutaka also likes hot foods (like oden), and animals; and her dislikes include milk, her sickly physique, and aggressive people.

She is also noted to be strong at Japanese class; and not suprisingly, she isn't all that good at athletics.


Yutaka is very small (shorter than even Konata). She has a "sickly" physique, and is skinny and flat-chested.

Yutaka Kobayakawa has reddish-pink hair that is usually tied into high pigtails using 2 blue or white ribbons, and green eyes. Her eye and hair colors resemble the color scheme of a watermelon, and she has pale skin.

Like most/all of the Lucky Star characters, she is sometimes depicted without a nose, has a certain face shape, abnormally large eyes that take up more than half of her face, colorful, messy hair, messy bangs, and fringe covering her ears.

Yutaka only lets her hair down when she is sick or about to sleep, as shown in a scene wherein she woke up very early in the morning to see Konata playing games. Yutaka is also shown with her hair untied in a flashback of her middle school life, where she was sick. In the flashback, Yutaka was feverish, and she was lying down on a futon, with a moist towel on her forehead.


Yutaka Kobayakawa has a weak immune system and would often get sick, so she was unable to make any friends in the previous schools she was in, which is why she was very happy when she befriended Iwasaki Minami, and eventually the whole class. She is very close to her older cousin Konata, and is innocent, as she lacks knowledge of ero-games, yaoi, and adult video games.

Yutaka is very appreciative of her friend Minami, and she is very grateful to have a friend like her, to the point that Hiyori Tamura pictured both of them as a yuri-pair and created a doujinshi with characters that resemble both of them.


Yutaka first appeared on the anime on episode fourteen, when she moved to live with Konata to help with the commute. During this episode she did her entry exam for Ryōō High School, on that day she met Minami Iwasaki, who let Yutaka use her handkerchief. After being accepted into the school, she became friends with Minami Iwasaki, Hiyori Tamura and Patricia Martin. Yutaka is the closest friend of Minami and is often the only one who understands the latter's behavior. Hiyori notices this and frequently fantasizes Yutaka and Minami being a yuri-pair and has even done some sketches for a doujinshi she is creating where the characters has an uncanny similarity with the two, but still fights the thought because of the fact that they are all friends.


Character song Vol. 5: Yutaka Kobayakawa contains 2 songs sang by Yutaka's voice actor, Shizuka Hasegawa.

The songs are:



  • In episode 18, when Konata and her friends play the animal personality game, Konata thinks Yutaka would be a squirrel.
  • Yutaka's voice and personality are very similar to Starfire from Teen Titans, because of her naïveté, and she is voiced by the same actress in a high pitched voice.
  • Yutaka is left handed.
