Hakua Shiodome (汐留 白亜 Shiodome Hakua?) is one of the main female characters in the Shomin Sample series. She is a genius in fields such as engineering, math, and science, and even has a special lab built specifically for her use at the academy.


Hakua is a teenage girl below average height for a fourteen year old, who has very pale skin and is often mistaken for a elementary student. She has short silver-white hair with a blue tint to it that only reaches down to her ears. She also has big, blue round eyes.

Hakua is usually seen with her school uniform; which consist of a white shirt and a brown collar, with a orange-brownish ribbon on it. And also a white and rather short skirt, white stockings and brown shoes.

Otherwise, she is seen with a long, loose sleeved button up with lace at the top, with a string tied in a bow, along with a murky purple skirt that is rather short, with white fold over socks that have lace on them.


Hakua has a very air-headed and quiet personality, and a very soft-spoken voice. She is shy and a extremely youthful autistic genius who was very antisocial.

But she has a very reserved demeanor, showing very little emotion and speaking very little. Despite this she is prone to eccentric behavior, that involves her unconsciously stripping off her clothes and recording things such as complicated mathematical formulas anywhere she can.

Hakua is an expert in mathematics and the sciences, and habitually documents new equations on any convenient walls. She goes into a strange daze at such times, and wriggles out of her clothes as she writes.

While she gives the impression she only prefers to talk to Kimito, she called the other girls (Aika, Reiko and Karen) her other friends as well which left them surprised and touched. This shows that she has no problems with them as she is shown giving them a riddle.

Hakua also seems to not like losing in anything, shown when Kimito gives her riddles that she could not answer. This prompts her to ask for more just to prove that she is good with riddles. She also displays this kind of personality when she plays rock, paper, scissors with Kimito and always loses, prompting her to demand a rematch until she wins.


Not so much known about Hakua's background, but she is from a rich family and has her own maids. Her family also owns a cellular phone company.


Kimito meets Hakua and sees her writing down complicated math formulas on the ground. Then she starts to take off her clothes, and Kimito tries to put them back again. He later brings Hakua to his room, feeds her, and they introduce each other-- and spend time in his room. Then Kimito walks Hakua home, though she wants him to stay, which greatly shocks Hakua's maids. And after this, they start to spend more time with each other, and Hakua later joins the Commoner Club.
