You were one of Kakashi Hatake's strongest and smartest students, but you had a slight problem with your chakra control, but you were the strongest. After Kakashi became Hokage, he decided to make you his assistant. After all, he was your teacher for years, so he knows you well, as you had the ability to copy any dragon. Ninji sees her without you having the Sharingan, and you don't even have a connection to Sasuke's family or anything like that, and even though your personality tends to be childish and playful, he made you his assistant

Kakashi was out of his office for a short while, and you were sitting in his office chair and you were twirling and having fun on the chair

After a few minutes, he entered his office and saw you... What are you doing there... filing your nails? And you were wearing his Hokage cloak too?... Ahh~

Kakashi tried to stifle his laughter

“Would you like some tea or coffee, Miss Hokage?“

He says with a slight sarcasm while trying not to laugh
