He is a middle aged man with his hair combed back and has a thick mustache. He usually wears a suit.
Light usually has a calm personality, but gets put on edge when the safety of his daughter Neon is jeopardized. He is very indulging of his daughter's whims. While it's unclear how much of his affection for her is sincere, a large part of his behavior is due to the value he places on her fortune-telling Nen ability. It has been revealed that exploiting this ability was how he got ahead in the Mafia, as well as how he maintains his position.
Light was originally just a minor provincial within the Ritz Clan in the Mafia community. However by shrewdly using his daughter Neon's fortune telling ability, he managed to surge his position in the Mafia Community.
Yorknew City arcEdit
Neon contacts her Father Light threatening to cease her fortune telling, for being flooded with more requests than she can handle, but after negotiating with him agrees to do them. On the night of September 1st, Head Bodyguard Dalzollene contacts Light from the Hotel Beitacle to inform him of disturbing news found on the most recent fortunes. Apparently most of the fortunes foretold death would happen to most of the members who will attend the auction. Seeing the danger in having Neon attend the Underground Auction, he forbids her to attend it and to pacify her emotions get her whatever she desires from the auction regardless of the cost. This however proves fruitless as she throws a giant tantrum, with Dalzollene at his wits end.
Exhausted from her tantrum Neon falls asleep and Dalzollene explains to Light, for the moment she's asleep, but she doesn't know how she'll act when she awakens to find out she missed the auction. Left with no other options Light cancels all of his plans and informs Dalzollene he's heading to Yorknew City immediately. He also orders Dalzollene to get the Queen of Colco Mummy just to keep his daughter satisfied. On the night of September 2nd Neon contacts her Father to inform him that all of the Underground auction items were stolen by thieves and Dalzollene may have been killed. Kurapika then talks with Light who reassures him that Dalzollene may have been killed, which baffles Light because of his credentials. Kurapika and Light then discuss what actions must be taken to ensure Neon's safety and Light promotes Kurapika to head bodyguard.
The afternoon of September 3rd Light meets with the bodyguards and is filled in the entire situation by them. He thanks them for clarifying the situation to him better and thanks Kurapika for his hard work and mentions that he's going to take his daughter home, much her chagrin. Light however reassures Neon that he'll retrieve the stolen items and orders Basho and Melody to guard Neon until she returns home and they should dress in disguise, since their pictures are on the Hunter Association Website. Neon is then sent to her room and then Light details to the bodyguards the Underground Auction would resume that very night, the Shadow Beasts aside from Owl are dead, and that the Ten Dons have hired Zeno and Silva Zoldyck of the Zoldyck Family along with a group of Freelance Assassins to eliminate and retrieve the stolen goods from the Phantom Troupe. However since this act would lower the reputation of the community, Light orders Kurapika to join them.
Later that night Light accompanied by Kurapika attend a meeting where the Freelance Assassins, Zeno and Silva Zoldyck, and Mafia head Zenji accompanied by some bodyguards all discuss a plan on how to deal with the Phantom Troupe. After the meeting Zenji confronts Light and after some hostile exchanged words and punches him in the face. Kurapika threatens Zenji with a knife, but Light stops him. Light admits he's made a lot of jealous enemies with his success, and will make more with his daughter's predictions and tells Kurapika, he expects great things from him and will award him generously for his efforts. Melody then contacts Kurapika to inform him that Neon has gone missing. Panic stricken, Light is assured by Kurapika that his daughter must have figured out he lied to her and is now heading towards the Cemetery Building as well. Light contacts the police to have them be on the look out for his daughter and is later contacted by one of them who tells him she escaped via a cab. Keeping a calm about the situation, Kurapika uses his Dowsing Chain Hatsu and a map to locate Neon.
Upon arriving at the Cemetery Building, Light immediately rushes to the room his daughter's in where she lays in bed unconscious. Searching the Hunter Association Website for any new information, Kurapika finds Neon's picture was uploaded onto the website. Enraged Light proclaims he'll kill the person who uploaded the picture of his daughter onto the website. Kurapika calms Light down and reminds him his daughter's safety is their top priority. He informs Light that he's already contacted Basho and Melody about the situation and they'll soon regroup with one another. Feeling insecure about Kurapika's plan, Light voices his concern about the auction, but Kurapika predicts the auction will once again be canceled. As soon as Neon was seen by a doctor and her condition stabilized Light along with an medical team take an ambulance car to transport Neon to a local hospital.
At the start of Underground Auction, Kurapika contacts Light and explains that his premonition was incorrect and that the Underground Auction has begun. With the next item on the auction being the Scarlet Eyes, Light orders Kurapika to buy them at regardless of the cost. Ultimately the Scarlet Eyes were purchased for a total price of 2.9 Billion Jenny, due to Zenji's interference. Although upset by the price paid for the eyes, Light figures he'll not only easily make the money back in no time, but rise to power even further with his daughter's ability. Regaining consciousness, Neon thanks her father for the eyes and forgives him. Outside Neon's hospital room Light congratulates the bodyguards for a job well done and informs the group on the following day, the Mareech Tissue will be up for auction and that the morning after the next he'll take off. Light also orders Melody and Basho to accompany Neon on another shopping the following day as well, much to their dismay.
Greed Island arcEdit
Sometime during the Greed Island arc, Light undergoes a serious breakdown after Neon's fortune telling ability was stolen. The breakdown is also caused by the fact the Kurapika bid 2.9 billion Jenny on the Scarlet eyes on his behalf and cannot pay it off.
Dark Continent arc Edit
Light's organization somehow survived the critical blow and is now led by Kurapika. The organization is apparently exclusively involved in legal activities, with its source of income being from gambling and bodyguarding.
