Hisako Arato

Appearance: Hisako has short, pink hair with bangs that reach down to her chin. In junior high, her hair had a rounder appearance. In the early parts of the series, she has a normal fringe reaching the length of the eyebrows. Later on, her fringe parts to the left. In her second year, her hair is a slightly shorter bob. She is 161 cm tall

She normally wears the standard Tōtsuki seasonal uniforms, even when not in school. She wears a plain white chef's uniform when she cooks. Hisako has been shown wearing glasses when working behind a computer.

Her measurements are: bust 80cm, waist 56cm and hip 79cm (31-22-31).

Personality: Hisako is a loyal friend to Erina and is almost never seen away from her. As her secretary, she helps organize Erina's tasks and assignments to allow her to focus on her work, showing an impressive amount of time management and secretarial skills, even more so considering that she is only a high school student. Much of Hisako's ambitions are to help out Erina and make sure that she stays at the top of the class, with Erina standing above her as her "Empress". This means that she tends to care more for Erina than she does herself, which has been the case since they were kids. Hisako is always fine following behind Erina and was fine being that way since childhood. She also helps introduce some modern things to Erina such as Shōjo manga, which she buys for her upon request. Much like Erina, Hisako is generally stubborn and prideful, often belittling others, usually in Erina's stead.

However, her pride as Erina's closest ally was severely damaged when she lost her Quarterfinal match in the 43rd Annual Tōtsuki Autumn Election main tournament against Akira Hayama. Since then, she sulked much more, believing that she was no longer worthy to be Erina's secretary, let alone her friend, despite Erina's personal protests. However, thanks to Sōma's advice, her resolve has changed. Now she wants to stand beside Erina rather than following behind. She has become much more friendly and even befriended Sōma during their week together, despite previous feelings towards him. A support character from Food Wars
