Living with his obsessed father, Alden Nougami since birth, He had to put up with his fathers' unique personalities, which often traumatized him. He wanted to be a traveler when he grew up and, unlike his father, had no interest in studying abaout the Digital World. However, this did not stop his curiosity that one day changed his life forever. While at his fathers' laboratory, His father and his memeber try to experiment to see if the minds of human beings could be digitized, an experiment that went wrong. Everyone began to evacuate however his son wasn't lucky where he accidentally stumbed on the newly-built machine, causing his molecular structure and his mind to become infused with all the digimon data.

His father was devasted when he saw his son's limp body, realizing he died from the acciddent which made him to closed down the project due to the grief of his son's death. However, he didn't know that his son who called himself Nanashi or Nanashimon was born that very day and the human he once was died.

He had no recollection of his past or the accident only the Digital World, not even his own name. Despite his molecular DNA data seems scrambled which made him a Glitch which he share all the attributes of the Digimon. He began to discover his own powers that he can bend reality by creating it. 

Not only that, he didn't realize he was the gateway whenever he was able to crossover to the human world. But there was a price, once he enter the human world then a small action could change everything (in other words, their destiny). Once he remained in the Digital World then the gateway closes, sending all the Digimons back to where they come from.
