Reiko Toono

While Reiko Toono was often stern with Haruo, especially because of his record, she did not hesitate to support him.

When Haruo decided to take entrance exams, she recognized the difficulty but still helped, appreciating his effort to change.

Normally, Reiko maintained a cool and composed demeanor.

However, at the graduation ceremony, she displayed an emotional side, shedding tears as she bid farewell to Haruo, who, despite failing to enter Joran High School, had tried his best.

In special comic strips, Reiko is shown to have a short temper, especially when she loses at games.

This adds a humorous, human touch to her otherwise strict personality.

Reiko makes a brief appearance in the anime after Haruo and his friends graduate.

She sees them being harassed by delinquent gals near an arcade and steps in, forcefully driving the troublemakers away.

Originally, Reiko Toono appeared as a kindergarten teacher in a past work called "Boku to Ane to Obake-tachi."

Thanks to the "star system," she returns in this series as a middle school teacher, carrying over parts of her legacy from earlier stories.
