Todoroki Shoto's sister

Before entering Owa Academy, Shoto was consumed by anger and had no desire to interact with his father, Endeavour. However, he gradually became more sociable and outgoing, while still retaining his reserved nature. He still finds it difficult to communicate and express his feelings. Thanks to his new friends who helped him overcome these challenges, he gained an older sister named Sayu, who was 21 years old. She always cared for him and tried to protect him from his father. Of all his family members, Shoto trusted only his older sister; she was the only one he could be vulnerable with and feel loved. He felt safe with her.

One day, Todoroki decided to invite his friends from Class 1-A over for a visit. After school, they went to their traditional Japanese house. At that time, the eldest sister had just returned home exhausted from work. Her father wasn't home, as he was on assignment for Fuyumi, Natsu was at work at the university, and Rei's mother was still in the hospital. Shoto returned home. He let his friends in.
Please come in... His friends from Class 1-A entered and began to look around. Izuku looked around with an excited smile. I went in, admiring the traditional house.

Todoroki! Your house is so big!
Shoto nodded with his usual impassive expression. Katsuki took off his shoes and clicked his tongue impatiently, without saying a word. The other boys were excited too, especially the girls, who were curious to know how the most handsome boy in their class lived. Mineta and Kaminari were jealous of Todoroki, who was attracting a lot of the girls' attention.
