Tsukasa Hiiragi

Tsukasa Hiiragi is one of the four main characters of Lucky Star. She calls Konata Izumi "Kona-chan" and is the only one among all the Lucky Star characters who does that. She is the younger twin sister of Kagami Hiiragi, and is also a member of the Hiiragi family.


Tsukasa Hiiragi is generally a sweet, naive, innocent and dimwitted person who never gets mad, similar to Miyuki. Her calm, girly, and friendly personality heavily contrasts with that of her sister, Kagami, who is a Tsundere and takes on a much more harsh, tomboyish, and arrogant attitude.

Tsukasa is often overshadowed and compared with her older twin sister, Kagami, because she does not seem to excel at anything, including studying and sports. Because her twin sister is much more capable than her, Tsukasa always needs help from her sister with tasks such as texting, much to the latter's rage.

She is an air-headed and clumsy person who lacks intelligence by nature, which is why she gets bad grades at school. She is also a heavy sleeper, and cannot wake up at a set time, even when someone is present to wake her up.

Unlike Kagami, who is rather weak in terms of cooking and other household chores, Tsukasa is fairly good at cooking and excels in home economics.


Tsukasa has an average build, albeit lacking any curves. Like Konata, she is quite small compared to her friends.

She has shoulder-length, light purple hair accessorized with a yellow headband that has a bow on top; the hair bow often changes position in correspondence to her mood. Her droopy "tareme" eyes are blue-violet, which seem helpless, nervous and emotional.

Her autumn uniform consists of a white long-sleeved blouse that looks extremely loose and makes her look thin. The sleeves of her blouse have dark salmon pink-colored cuffs with two thin, white horizontal stripes going around them, and a dark salmon-pink collar that also has two thin white stripes, with a light salmon pink necktie that is often shown in the anime without a knot, resembling a butterfly. Her skirt is short, reaches her upper thighs, and is the same color as her collar and cuffs. She also wears white socks that reach the middle of her calves, like her sister, Kagami, and brown loafer-like school shoes.

She apparently looks a lot like Akari Kamigishi from the anime To Heart. This is referenced twice in the anime. In one episode, Konata's birthday present to Tsukasa is a uniform worn by Kamigishi in To Heart. In another, Tsukasa was mistaken for a cosplayer and had her photo taken when she and her friends went to Akihabara together.

Hiiragi Family

Tsukasa Hiiragi comes from a very religious six-member family. She has three sisters, with the eldest one being Inori Hiiragi, the middle one being Matsuri Hiiragi, and an older twin sister named Kagami. Tsukasa is the youngest member of the Hiiragi family. Her mother is Miki Hiiragi and her father is Tadao Hiiragi.
