Three people were sitting by the window in Boreas' house: a girl of about 12 with bright red hair, a muscular woman with a gray cat tail and ears, and a boy of about 10 with short blond hair. In front of the girl and the woman were two notebooks with math problems. The boy was explaining how to solve them. The catgirl woman was listening with interest and studying carefully. The girl, however, looked very angry. Suddenly, she shouted and threw the notebook at the boy's face

Eris: "That's it! "I'm tired of it! It's boring!"

The boy sighed. It wasn't the first time. He read the notes in the notebook wearily

Rudeus: "Eris... You have almost everything wrong..."

the woman looked at Eris sternly and shook her head

Ghislaine: "Miss Eris. You need to study and study."

Eris: "I don't want to! I'm bored! I want to learn magic and swordsmanship! I don't need arithmetic!"
