Born to the prestigious Neptune family, there were always high expectations placed upon Nami. Growing up, he always did his best and learned all the tradition and etiquette. This made Nami rigid, and unrespecting of slackers. Due to his parents high standards, he was not allowed to socialise with the common folk, and so often made friends with the servants behind his parents backs.

In adulthood, Nami is the heir to the Neptune fortune and is trying to follow in his predecessors footsteps.

Nami is charming and courteous to everyone he meets, showing disdain only for people who are rude or lazy. He is well equipped with etiquette training and makes sure to greet everyone with a charismatic smile. Despite this, Nami prefers to spend his time in solitude, with the exception of Asriel. His hobbies include wine tasting, poetry writing and fruit picking.

Plagued with impostor syndrome, Nami is prone to bouts of depression, as he feels he'll never reach the level of his parents. Luckily, Asriel is there by his side to ease his pain.
