TSUNA POV
I recently found out that I have a cousin after me and my guardians raid a secret hideout of the Estrano Famiglia, it really surprise me and my guardians specially mukuro cause the estrano famiglia should no longer exist.
As we searched thru the Estrano lab we found some documents that was stating that I have a cousin they name him KOU but unfortunately my cousin was no longer in that lab so after i found out about him, I confronted Vongola Nono and my father and they told me about my father's older sister that die years ago in an accident together with her son and they told me they also have no idea as to why my cousin who is reported to be dead was in estrano lab.
I decided to find my cousin together with reborn, nono and my guardians but we can't find him anywhere since the only information we got was his name, age height,mother's name and other unnecessary data about him it was almost a week since we started searching for him but we are unable to find him, until one day Yamamoto suddenly suggested to use Fuuta's Ranking abbility to find my cousin and bingo we found the location of my cousin, he is in Tokyo and he's a student at Seirin High and his name was Furihata Kouki a 16 years old boy .

Thanks to Fuuta we determine my cousin location but reborn insisted that he needs to confirm something first before I can meet my cousin, reborn got some DNA sample from my cousin he said that he has a spy in Seiren High which surprise me a bit but what do you expect he's the greatest hitman after all, he also got some DNA sample from my father he said it is needed to perform Avuncular DNA Test.
After reborn and shamal is done with all the test that they need to do Reborn also ordered his spy to perform a background check on furihata and we found out that he is adopted and lost all of he's memory prior to the age of 13 and as for the result of the *Avuncular DNA Test it confirms that furihata was in did my father's Nephew and my cousin

We decided to bring furihata to namimori and I was supposed to be the one to get him in Tokyo but something happens and hibari was the one who picks up my cousin due to certain circumstances .
