So what is the canon info that we have on Neige Leblanche? Like from the canon story and the special event like Glorious Masquerade.
He is a sophomore at Royal Sword Academy, so he is ~17 years old.
Neige is considered “the most likable celebrity in the world”. He is known for “his disarming good looks and approachable nature”.
According to Mira, Neige been called pretty/beautiful more times than Vil has (based on Magicam comments).
Cater says that Neige is a top Magicam influencer.
Vil is often playing Neige’s evil counterpart in various productions. For example, he was given the offer to play the villain in the sequel to Legendary Sword, while Neige was to play the hero.
The rivalry between Vil and Neige appears to be entirely one-sided. Neige seems oblivious to Vil’s hostility and resentment of him, acting very friendly and inviting Vil to join him for singing and dancing.
His fan club name is “Eternal Snow”. Rook is its second ever member.
There are hairclips Rook wears with his pajamas which are rare items only avaliable to members of Neige's fan club.
In Glorious Masquerade, Neige throws himself in front of fire lotuses to save Rook and Epel.
The Seven Dwarves state that they want to win the Harveston Sledathon so that they can share luck with everyone and make the world a happier place. “We know we can't make everyone happy all by ourselves. But if those close to us can be happier, like Neige... Then when other people see his smile, it'll lift their spirits! That's how we want to share it.”
The first time Vil co-starred in a movie with him, Neige would frequently leave. He would do his chores, attend rehersal, then go home and do more chores. He'd practice for the movie in what little spare time he had, and still always managed to cheerily greet Vil.
Neige has lived with the dwarves for years. They have been supporting each other for a long time (since he was child) and do not seem to have any adults in their lives.
Neige has never divulged his personal history to the press.
Rook states that Neige’s smile is that of “someone who’s overcome untold hardships. That’s why so many people are drawn to it.”
He apparently donates most of his pay to charity in order to aid underprivileged children with their futures. This is also something undisclosed to the public, but is known among his most dedicated of fans.
Like Vil, Neige was a child actor.
He won the title of Best Actor at the prestigious annual Diamond Movie Awards. Neige is considered the youngest recipient at 14 years old.
Rook calls him “Roi de Neiges”.
Rook had trouble expressing his emotions as a child—until the fateful day that he watched the musical King’s Road, which starred Neige as the lead. The entire performance and its combined elements brought Rook to tears.
The very first time Rook dressed up to attend a performance was after he transferred to Pomefiore from Savanaclaw. Vil helped him get ready to see a show starting Neige.
Neige is seen in commercials for Red Apple Soda and Félicité Cosmetics’ Precious Protection Foundation in book 5.
Neige says he hasn’t seen Vil since the last movie they filmed together.
Neige is described as having perfectly choreographed walking and talking. His aura is also described as less intense and less glamorous than Vil’s, his smile like “a tiny flower blooming in an open field.” NPCs also call him very “accessible”, “friendly”, and wholesome”.
Neige is happy to hear Vil singing; he compliments Vil’s voice and calls it “absolutely incredible”. He also tells Vil that he looks forward to their VDC/SDC performance and encourages Vil after NRC’s loss.
Vil and Neige’s first production together was a musical drama set in a school. Neige was the star and Vil was their bully.
Neige chooses to perform an arrangement of a popular nursery song from the Shaftlands for VDC/SDC. He says he chose it because he “[wanted] to have a fun time and [to] share it with everybody watching the SDC. [He] figured something familiar would be the way to go [… he] wanted to share some special memories with [his] friends at school. […] if [they] could get the whole world to sing along with [them], it would make for an experience [Neige and the dwarves would] treasure forever.”
He’s been wanting to try apple juice from the Felmier family farm ever since Vil made a post about it on Magicam.
Neige was hypnotized by Jamil to sing for the cultural fair attendees. This served as a useful distraction while Yuu and co. dealt with OB Vil.
He seems to enjoy singing with others, be it the Seven Dwarves, NRC students, or whoever else wishes to join.
Neige recognizes Rook as “R”, a fan who goes to every single one of his meet-and-greets and writes him letters. R also buys each of his photos at fan events and composes poems to share his impressions of each photograph. In fact, Rook brought his Neige photo album with him to Ramshackle for their training camp!
Neige was surprised to find out R was a man, but quickly accepted it and encouraged Rook to please sign with his full name in future letters.
Jamil remarks that Neige handles situations with grace. “He's a leading global celebrity, but he still treats fans warmly and attentively. That's definitely a strength.”
Neige had never seen Vil cry outside of acting until NRC’s loss at VDC/SDC.
A movie adaptation of a children's novel starring Neige (~11 years old at the time) pulled in twenty million madol/thaumarks its first week.
He has a radio show, which Rook listens to at night.
