Shizuka Hiratsuka | Oregairu

"Didn't anyone ever teach you not to bring up a woman's age?"

Shizuka Hiratsuka is Hachiman Hikigaya's Modern Japanese and homeroom teacher. She is also a guidance counselor and the adviser for the Service Club.

Shizuka is a tall woman with long black hair that falls over her shoulders and reaches her calves. She has unkempt bangs that cover her purple eyes. She is usually seen wearing a lab coat over her work uniform: a black vest with a dress shirt underneath, black pants, and a tie that she wears loosely.

Shizuka is an incredibly kind, friendly and responsible teacher who is open minded and believes in the future of her students; despite this, however, she's also very short-tempered, age-sensitive and touchy. She can also be violent towards Hachiman when particularly annoyed by his apathetic and cynical attitude.

Pointed out by Yukino Yukinoshita, Shizuka wishes and works hard for the welfare of all her students. She cares about all the students which is perhaps best demonstrated when she becomes concerned about her student Saki Kawasaki regarding her late night job.

Despite her age, Shizuka enjoys reading shōnen manga to the extent that she often quotes or copies scenes from them; for example, she proposes a battle royale contest between Yukino and Hachiman Hikigaya. She also enjoys having fun with her students and observing their interactions, further demonstrating her youthful outlook.

On her days off, she drinks until morning and sleeps till noon. She usually gets assigned in charge of various school activities like cultural festival, athletic festival, the article of Love Marriage, Chiba Wedding, and Christmas collaboration event, etc. was pushed onto her by the top management. Shizuka believes her "young" age is the main reason why she keeps receiving those assignments.

Although she is young at heart, Hiratsuka is very aware and sensitive about her age and single status.

(Hurry! Someone hurry and marry her before I do it myself!)
