Kakashi Hatake had never said anything about his family; he never talked of Minato being a second father when his own had passed. He never talked of Obito being that little brother who was always trying to surpass him. Rin, well she was possibly his older sister stereotype or his girlfriend. But that was Team Minato not his real family.
His real family was Sakumo Hatake and Mijuno Hatake his parents, Sakumo died protecting his team, his mother died in and hidden Sand attack on Leaf Anbu force. He also had a son who was sent to be trained in another country; he was son of Kakashi and Hanare. He was called after Tobirama which in fact he dressed and looked like. He mastered every type of jutsu and has a half sharingan on his left eye, coming from tiny bits of DNA traced of Kakashi.
He created his own jutsu which was S Ranked sentinel lightning Streak. Kakashi had to send him a way to prevent his kidnapping. But now there was a need for him to come out. A group known as equalisers were hunting down every clan in the hidden leaf to create a new kekkei genkai eye that gave the ability to do secret clan jutsu such as kushina and Karin's golden barrier chains.
