Nagito was born into a wealthy family and extraordinary luck, causing him to experience repeated cycles of extreme bad luck followed by even greater luck. His pet dog was killed after being hit by a truck, devastating him. The good luck that came afterward, but, remained unmentioned. Another cycle came while he was in elemantary school, boarding a plane alongside his family from the San Cristobal airport. Once they boarded, the plane was hijacked and a meteorite the size if a closed fist struck the airplane at the right time, hitting the hijacker and his parents, who died. The surviving Nagito believed it was all from a pure luck and obtained his freedom to live all by himself cuz he had no other living relatives. Though he did have a strained relationship with his parents, his mom never complimented his appearance which he doesn't care(maybe) and later, while getting kidnapped by a murderer, Nagito found a lottery ticket inside the trash bag had stuffed him in. After he was safely taken to police, he discovered the lottery ticket was worth 300 mil.dollars which made him obsessed with his luck even more only causing him to be a little crazed over by hope. Nagito also learned about he has 3 malignat lymphoma accompanied by frontotemporal dementia while attending spiral high school. After that, he won the annual lottery to attend Hope's peak Academy, an institution he idolized as the Ultimate Lucky student, it was all good but Naito declined the offer, thinking he didn't deserve it and only gave in after the academy wanted to research his incompresehensible talent.
