Rizu Ogata

Rizu Ogata is one of the main characters from the We Never Learn anime and manga.

Another third-year who is prodigy in mathematics and science, but near-completely hopeless in literature and the arts, which are the fields she prefers. The daughter of an udon restauranteur, Rizu seeks to pursue a degree in psychology to better understand people and herself, far from the methodical nature of the STEM fields.

In the AWA fics, Rizu debuted in Chapter 45 of All Worlds Alliance Stories.

Appearance
Rizu is a short but well-endowed girl who wears glasses. Rizu has light brown hair and blue eyes. She is very short at 143 cm (4 feet 8 inches), yet has the biggest bust size among the female protagonists at F cup, and possibly G when she measured it again in chapter 44.

She wears school uniform which is a half-sleeved or a long-sleeved depending on the seasons, informal styles. At home when she's working, she wears kimono working attire with an apron that says Ogata Udon. Her arms are extremely thin, long and soft as well, as she seems to lack any apparent muscle tone; which is probably why she doesn't normally wear sleeveless clothing.

Personality
Rizu although is seen to always have a poker face on, she is capable of showing emotions whenever she's happy or down. A math and science genius since young, she is known as the "clockwork Thumbelina". However, she isn't good with reading people's feelings and emotions, thus failing her humanities and not recognizing that she is in love with Nariyuki. From the time she was young she was never satisfied with a vague answer, which she finds humans emotion to be incomprehensible as compared to mathematics or science, and is oblivious to her surroundings once she's focused on something.

She is also very timid as even though she says doesn't believe in superstition beings, she got scared easily when she watched a horror movie by herself. She also tends to misunderstand things a lot as seen in Question 37 and Question 44.

She is a very serious girl, always wants to understand human behaviors, especially love issues, by scientific methods. She is extremely determined, and sometimes stubborn, to attain psychology in university, although the reasons had been changed in later chapters.

She is poor in interpersonal relationships, sometimes difficult to express appreciation to close friends such as Sawako Sekijou.

She is highly influenced by her grandmother, who died in her childhood. She once misunderstood that she was hated by grandmother as she relied on her grandmother so much. She finally understood her grandmother and played games with her own friends in Question 117.
