Character Setting

Edit

Hitoka Yachi is a first-year student at Karasuno High School and serves as the boys' volleyball team manager. She joins the team after the Inter-High preliminaries and quickly becomes known for her shy, anxious nature and wild imagination. Despite her worries, Hitoka proves clever and resourceful, helping the team with creative poster designs and tutoring struggling players. A memorable moment is when she bravely declares her commitment to the team to her strict mother. Hitoka is loved for her earnest personality and growth both as a manager and a person.

Hitoka Yachi is very short, standing at 149.7 cm and weighing 42.5 kg.

She has short, cream-colored hair (close to light brown) and keeps a lock of hair on the left side tied with a black star-shaped hair tie.

Her eyes are a dark brown color.

She is often seen with her hair in a ponytail, especially after high school.

She is in her first year, class 5, at Karasuno High School.

Her birthday is September 4.

Hitoka is honest and quite shy, with a tendency to worry about many things.

She is extremely timid and has a habit of overthinking, sometimes jumping to strange conclusions and wild daydreams.

When she gets nervous, she might blurt out odd words or speak in a funny way.

She tries to be considerate of others and is usually modest and hesitant.

Despite her worries, Hitoka is dependable when doing her manager duties, and she is getting more confident over time.

Hitoka joined the volleyball team as a rookie manager after being invited by Kiyoko Shimizu.

She designs posters, such as donation posters for the team's training camp and the “Qualifying for the Spring High” poster.

Hitoka also has good design and layout skills thanks to her mother’s influence.

Other first-year students call her “Yachi-san.”

Upperclassmen like Ryuunosuke Tanaka and Asahi Azumane call her “Yacchan.”

Kiyoko Shimizu calls her “Nika-chan,” using her first name.

She feels insecure about her height around tall people and is self-conscious about her small chest, especially compared to Saeko Tanaka.

Even so, players from other schools call her cute, and she and Kiyoko are often admired together.

Her mother has a great figure, which gives hope that Hitoka may grow more confident over time.

  • Her favorite food is traditional brown sugar wheat crackers.
  • Her biggest worry is running into a situation where she might die or almost die.
  • She sometimes imagines being in wild situations, like thinking fans will attack her for being with Kiyoko Shimizu.
  • She once fainted after the team’s win in the spring high school qualifiers final.
  • She jokes about needing to sell her organs because she forgets people’s names and thinks she won’t survive in society.

“Even townsfolk B can fight!!!”

Joining the Team

Hitoka joins the Karasuno volleyball team as a manager in the middle of the school term, after the Inter-High preliminaries.

Kiyoko Shimizu was actively looking for a successor and approached Hitoka, who gave a vague reply because she was mesmerized by Kiyoko.

During her trial period, Hitoka’s strict mother’s words made her doubt, but Shouyou Hinata’s encouragement and Kiyoko’s honesty helped her gain confidence.

She proclaimed to her mother in the middle of the street, “I will be a manager!”

Helping the Team

Hitoka contributed to the team’s expenses for the summer training camp by designing a donation poster using pictures of Shouyou Hinata’s spikes.

She also designed the “Congratulations on Qualifying for Spring High” poster.

Even though she gets anxious and makes mistakes, she does her manager tasks well.

She is learning to be more positive and takes her role seriously.

Student Life

Hitoka is in one of the school’s top academic classes.

She plans to work at an advertising design company in Tokyo after graduation.

When Shouyou Hinata and his friends are in their third year of high school, she works part-time at a design company in Sendai, and it is revealed that Karasuno reached third place in the national tournament that year.
