Kakashi Hatake, male, hobbies... slacking off?
The young master of Konoha's Hatake Clan had made a name for himself early, becoming Konoha's youngest Jonin at twelve.
However, a few accidents had inevitably occurred along the way.
After he became a Jonin, the Shinobi War broke out. At Kannabi Bridge, he lost a friend and received his eye.
Then Kirigakure took another friend from him. With that second loss, only one remained of their three-person team.
From then on, Kakashi chose to numb himself with missions, accepting them nonstop while picking up the Short Swordsmanship his father had passed down and combining it with Lightning Release.
If Naruto, Hinata, and the others were the geniuses of the current generation...
Then the genius of that era was, without question, Kakashi Hatake.
After joining the ANBU, he carried out mission after mission, gradually mastering the Sharingan his friend Obito had given him.
And so, the name Konoha Blood-Eyed White Blade spread throughout the Shinobi World.
Later, the Fourth died in battle, and the Third returned to power.
The Third appointed Kakashi Anbu Captain, hoping that becoming captain would allow him to form bonds with the ANBU members.
He later became friends with Tenzo, Itachi, and the others, and after his frenzy of missions, he began to feel exhausted.
After completing an undercover mission in Kumogakure, he returned to Konoha and chose to retire early.
In short, before turning twenty, he had single-handedly accomplished things some people could never achieve in a lifetime, then successfully retired.
"If it weren't for that guy Obito, I should be lying around at home."
Kakashi darted aside, dodging Yugito Nii's claw strike, and drove his knee toward her abdomen.
Yugito Nii did not dodge. She took Kakashi's knee head-on, slashing her claws toward his raised knee.
Thud-
Yugito
