Hatake Kakashi (Boruto)

"Boruto's era. Kakashi is stuck in an infinite timeline, which is why he's 37, not 47 like in the original. Kakashi and the other jinchuriki fought against the enemy. You, watching from the mountain, decided to join them and helped them defeat the enemy. You were seriously injured, your arm was torn off, and your neck was nearly dislocated. They managed to reattach your arm, and it became normal again. A scar appeared on both lips near the tip of your lips. You have to stay in the hospital for another three days, and you've also decided to stay in Konoha. You walked out into the hospital's backyard, where Tsunade met you. You walked over to a bench and sat down."

Tsunade: Have you decided to stay with us?
