Character Setting

Edit

Ryoma Terasaka is a big, tough-looking student in Class 3-E of Kunugigaoka Junior High, well-known for his loud attitude, short hair, and rough personality. At first, he was one of the least motivated students, doing badly in school and being openly defiant toward Korosensei. Ryoma used to bully other students and struggled to fit in, feeling lost and alone, especially after getting separated from his old group. Even though he had a rough start, Ryoma gradually learned to trust his classmates and become an important part of the team. Over time, he showed great courage, loyalty, and even some hidden smarts, surprising those around him. After graduation, he became an assistant to a politician, working hard to reach his big dreams.

Ryoma Terasaka is a big, strong boy. He has a big build and a shaved, flat-top haircut, which makes him look even tougher. He often stands out because of his size and his loud, rough ways.

Ryoma is bossy, loud, and sometimes rude. He used to bully weaker students and liked to feel important.

At first, he did not care about school or the assassination missions, and he rebelled against Korosensei.

Ryoma often acts before he thinks, which gets him into trouble.

However, he is also brave and will protect people he cares about.

If someone helps him open up, Ryoma shows he can be a loyal friend.

He is not afraid of hard work and tries to fix his mistakes when he realizes them.

Ryoma was a typical bully since elementary school, using his strength to control others.

He was good at school and entered Kunugigaoka Junior High, a top school.

But his old tricks did not work there, and other students made fun of him.

His grades went down, and he ended up in Class 3-E.

After joining, he tried to boss around students who were also feeling lost.

But when Korosensei became their teacher, Ryoma’s plans failed.

This made Ryoma feel even more angry and left out, not just from the whole class, but also from his group of friends.

Ryoma is physically strong and has a lot of energy, which can make him a strong asset in fights or sports.

Even though he acts dumb, he can understand things when he tries, especially if someone keeps him calm.

He is good at quick, direct action and isn’t afraid to jump into challenges.

He bought and used a stun gun for assassination missions.

  • Ryoma starts out close with Taisei Yoshida and Takuya Muramatsu, but he loses their trust when he acts selfish.
  • He fights a lot with Korosensei but slowly learns to respect him.
  • Karma Akabane sees Ryoma as strong and brave, despite his rough attitude.
  • He unexpectedly becomes good friends with Kotaro Takebayashi and often hangs out with him.
  • He also becomes good at cheering up and supporting classmates like Itona Horibe when they feel left out.

Early Days and Isolation

Ryoma is one of the first students to plot an assassination, forcing Nagisa Shiota to try a dangerous attack on Korosensei with his group.

This fails, and Ryoma's harsh methods get him scolded by Korosensei.

Losing Friends and Chasing Power

He tries to control other students in Class 3-E, but his bullying does not work anymore.

He is left out even by his old group: Taisei Yoshida, Takuya Muramatsu, and Kirara Hazama.

Ryoma’s loneliness grows, and Shiro (the villain) takes advantage, using Ryoma in a plan against the class.

Realization and Redemption

After causing trouble, Ryoma is scolded by Karma Akabane.

He feels deeply sorry, joins the fight to help the class, and helps drive away Shiro and Itona Horibe.

After that, Ryoma works hard to get along with everyone and joins in class missions, using his strength and determination to help.

In the hotel fight, Ryoma hides the fact he is sick from a virus so he can join the mission.

He successfully uses a stun gun to help during a big fight, showing courage and quick thinking.

He helps Nagisa calm down when fighting Akira Takaoka and throws Nagisa the stun gun—showing he trusts and supports his friends.

New Friendships and Growth

Ryoma starts hanging out with Kotaro Takebayashi, bonding over a visit to a maid café, and soon becomes a regular and even joins in recruiting others.

He opens up more, learns from his mistakes, and becomes a better classmate.

When Itona Horibe is left alone, Ryoma steps in to help, remembering his own tough times and helping Itona find his place.

  • Ryoma sat in the last seat on the window side in the 5th row.
  • Some classmates nicknamed him "Fake Takaoka," while children in Wakaba Park called him "Giant Gorilla."
  • He was forced to take extra classes called "NARUTO" to help with his bad grades.
  • Ryoma started out being bullied in his new class but turned into a caring friend.
  • He became a regular at the maid café, even making a stamp card and bringing new people near the end.
  • After graduating, Ryoma was picked by a politician for his guts and strength to become a secretary while still a student.
  • Originally, he had not thought about his future, but because of Karma Akabane's suggestion, he secretly picked "politician" as his second career choice.
  • Ryoma even performs an English rap in the song "Bye Bye YESTERDAY" with his group for a special album.

  • In his final school results, Ryoma ranked 4th in leadership and 5th in knife combat (team with Itona).
  • During his internship, he worked as a political secretary and was hired full-time after graduation.
  • Working with politicians made him want to become a real politician himself, aiming for a deeper understanding and a better personality.
