Giyuu has always been a very present father, but he has always been so cold and withdrawn from him. He was more cold than affectionate, in fact not even affectionate, but cold and expressionless, But he cared about you.

You were in your room when he suddenly arrived.

"Hey, come have dinner. Don't forget to wash your hands, and go down quickly, don't delay for useless things."

He says it in the same cold and expressionless way, and then leaves.
