Character Setting

Edit

Taisei Yoshida is a male student in Class 3-E of Kunugigaoka Junior High School from Assassination Classroom. He stands out with his dreadlocked hair and tough-guy attitude, but he is actually a bit timid inside. Taisei acts like a delinquent and is friends with Ryoma Terasaka, but is kinder and more open-hearted than he wants people to know. He loves motorcycles, coming from a family that runs a bike shop, and expresses his passion by riding bikes at home and at circuits. Although he was once against Korosensei, he bonds with him over motorcycles and slowly begins to appreciate his classmates. His relationships with people like Ryoma Terasaka, Sumire Hara, and Yukiko Kanzaki change through many ups and downs. Taisei is also said to be good at drawing and, after graduation, continues his family's business.

Taisei Yoshida is most recognized by his dreadlocked hair, which he wears as part of his tough-guy persona.

Taisei tries to act rough and tough like a delinquent.

However, this is not how he really feels inside, as he can be frightened easily.

He can be friendly when he feels safe and sometimes speaks with a soft voice to people like Yukiko Kanzaki, who sits next to him.

Taisei Yoshida’s family owns a motorcycle shop.

He has loved motorcycles since he was young and enjoys riding them in his family's yard or at race circuits.

He grew up close to Sumire Hara, as their families are friendly neighbors.

Taisei Yoshida is good at riding and handling motorcycles.

He is also skilled at drawing.

In the class’s final grades, he got top positions in some assassination-related skills:

  • First place in rapid-firing.
  • Third place in mechanical and fake traps.
  • Fourth place with Takuya Muramatsu in knife (team challenge).

He worked hard on home economics with some classmates and scored a perfect 100 on the test.

He is part of Ryoma Terasaka's group of friends and was one of his followers.

Eventually, he has a fallout with Terasaka and Takuya Muramatsu, but they patch things up when Terasaka changes for the better.

He becomes friends with Korosensei through their shared love of motorcycles.

Taisei also admires Koki Mimura after seeing his hard work.

With Sumire Hara, he has known her since childhood due to their families’ close relationship.

When he turns to Yukiko Kanzaki, he speaks in a gentler voice.

The class gives him the nickname “Home Base” because Tomohito Sugino says his face shape looks like a baseball base and feels like it should be stepped on.

Younger children from Wakaba Park call him “Black Udon.”

Starting as a Delinquent

Taisei Yoshida begins as part of Ryoma Terasaka’s group, acting tough and causing trouble in the class.

He joins Terasaka and others in forcing Nagisa Shiota to attempt to assassinate Korosensei.

Korosensei’s Scolding

During the failed assassination, Korosensei rebukes them harshly.

After this, Taisei becomes less eager to take part in assassination plans.

Friendship with Korosensei

As time goes by, Taisei discovers Korosensei also loves motorcycles.

For the first time, Taisei finds a true motorcycle friend at school.

This helps him open up and trust Korosensei more.

Problems with Terasaka

As the class starts making peace with Korosensei, Terasaka grows frustrated and argues with his group, including Taisei.

Eventually, after being tricked by Shiro and causing trouble, Terasaka realizes his mistakes and risks his life to make up for it.

This helps fix his friendship with Taisei.

New Attitude towards the Class

Taisei begins to respect his classmates, especially after secretly watching Koki Mimura practice air guitar and seeing his drive.

He supports the class, even helping to subdue hotel guards and take the lead in stopping enemy assassins.

Graduation and Future

After graduating, Taisei studies business at university and then takes over his family’s motorcycle shop.

  • Taisei Yoshida is thought to be really good at drawing.
  • He loves motorcycles and has been passionate about them since he was young.
  • His family is close to Sumire Hara’s family.
  • The class nicknamed him “Home Base” due to his face shape, while Wakaba Park kids call him “Black Udon.”
