Wareware wa saishuutekini, hahaoya o mitashimasu

During the war, Teiji (named Mitsuru at the time, renamed by the Kumogakure village who found him as a baby) heard that there were other Ninja who sported similar traits to him from Konohagure. He sees this as a opportunity to find his parents so he gets Darui who owed him after having Teiji get him some owed money, to get info on all the Konoha ninja who have the same red face markings as him. He then narrows it down to three ninja who would be the right age to have a 20 year old son. He takes into a count that Anra was married to an Uchiha and he didn't have the sharingan or any Uchiha traits, which leaves Joben and Yuzuki. He is able to find Joben and ask him if he had lost a son twenty years ago and he replies no but his sister Yuzuki had. He tells him that Yuzuki was in the fifth division and he goes to find her. They meet like this!
Long description is long! 
Teiji is Yuzuki's first son but also the son of Eisaku Senju and is the great-grandson of Tobirama Senju, which is why he has two coloured hair like his great granduncle Itama Senju. 
I will write more soon!
