List of Durarara!! characters

The following is a list of characters that appear in the light novel series Durarara!!.

Celty Sturluson

 * Seruti Sutururuson (セルティ・ストゥルルソン)
 * Online Alias: Setton (セットン)
 * A member of the Dollars. Also known as "The Black Biker" or "The Headless Rider", she is a Dullahan from Ireland who came to Japan looking for her stolen head. Her motorcycle is actually a disguised headless horse called a Cóiste-Bodhar. She has no heart and perceives via unknown sensors that are not located on the head; she's explained her "vision" is wider than a human's, but not a complete 360°. The physical strength she possesses is above human, though not quite on par with Shizuo Heiwajima. She is also capable of manipulating a shadow-like, durable substance to form objects ranging from gloves to chariots at her will as well as use the shadow-like substance to alter her outfits to go with different occasions. Celty has lived with Shinra for the past twenty years. Celty has developed a reputation as an urban legend, with many of the rumors circulating about her being true. She was initially hesitant about revealing her true nature to anyone; however, upon revealing it to Mikado, who reacted with awe rather than fright, she became far more open to doing so. She works as an underground courier, often in collaboration with Izaya despite not particularly liking him, and wears a helmet when she goes out and communicates via a PDA. Later, she becomes one of Mikado's and Anri's most trusted allies. She enjoys online chatting, television and DVDs. Over the course of the series, her relationship with Shinra intensifies; eventually, she says that she is in love with Shinra. She has a habit of punching Shinra in the stomach whenever he talks about his love for her. She tends to get mad when Shinra says she does not need her head. Despite being a supernatural creature, she is afraid of extraterrestrials and has developed a fear of traffic officers as they started pursuing her frequently. Her biggest fear, however, is that if her head is destroyed, the same may happen to her. Unbeknownst to Celty, Izaya has possession of her head before Kasane stole it and gives it back to its rightful owner. Upon being restored afterwards, Celty became amnesic with Shinra deciding to help her regain her memories or make new ones as she attempts to readjust to life in Ikebukuro again. Her name is a reference to Snorri Sturluson, who wrote the Prose Edda, where Valkyries appear. Celty also appears in Shin Megami Tensei: Devil Survivor 2 as a playable character per downloadable content.

Mikado Ryūgamine

 * Ryūgamine Mikado (竜ヶ峰 帝人)
 * Online Alias: Tarō Tanaka (田中 太郎)
 * A very shy first-year high school boy who moves to Ikebukuro thanks to encouragement from his best friend, Masaomi Kida. Originally from Saitama Prefecture along with Masaomi, he moved in hopes of having a more exciting life. At first, Mikado appears meek and heavily trusting but does show moments of self-confidence. A running gag throughout the series is that characters often comment on his fanciful name whenever they meet him. It is later revealed that he is the only remaining creator of the Dollars, a gang in the series and by extension its leader. He is infatuated with Anri, but has never found a chance to tell her. Mikado often gets advice from Izaya Orihara, particularly in relation to the Dollars and his need to seek out a life that is not ordinary. As the series progresses, Mikado begins to show a darker, more calculating side to his personality, and also becomes the temporary leader for the Blue Squares, contracting with Aoba in the sixth novel by stabbing him in the hand with a pen. Mikado's ultimate goal is to live a happy life with Masaomi and Anri, but his methods gradually put him at odds with them.

Masaomi Kida

 * Kida Masaomi (紀田 正臣)
 * Online Alias: Bakyura (バキュラ)
 * A resident of Ikebukuro and Mikado Ryūgamine's best friend from childhood. He was the one who encouraged Mikado to come to Ikebukuro, having moved there three years prior to the series. Masaomi is a jokester and playboy, frequently telling cheesy one-liners and hitting on girls, including Anri. Though this was originally his true persona, it is later revealed that it became a mask to hide his inner depression following his girlfriend Saki Mikajima getting kidnapped and injured during a gang war between the Blue Squares and Yellow Scarves, the latter of whom he led at the time during his middle school years. After Anri is injured during the Slasher incidents and the rising presence of the Dollars, he is forced to become the leader of the Yellow Scarves once more and seek revenge for his friend. Because he had once been the 'shogun (leader)' of the Yellow Scarves, he possesses a talent in fighting, and it has even been implied that he had taken down countless gangs single-handedly during his 'shogun' years. He despises Izaya for manipulating him when he first formed the Yellow Scarves, but returns to him again for information about the leader of the Dollars and discovers it is Mikado. He leaves Ikebukuro with Saki after the conflict between the three main forces in Ikebukuro. Masaomi's main goal is for Mikado to never learn the truth about Ikebukuro and live a happy life with him and Anri.

Anri Sonohara

 * Sonohara Anri (園原 杏里)
 * Online Alias: Saika (罪歌) and "Singsong"
 * A bespectacled girl who attends the same school as Mikado and Masaomi. She is the class representative along with Mikado. She is rather quiet and timid and seems very close to Mikado and Masaomi, but she tends to keep to herself. Though she knows Mikado's feelings for her, she considers herself unable to feel "love" towards anyone. She is somewhat popular, even though she feels uneasy about it. She feels as if she needs to rely on somebody to move on, specifically Mika when she was younger and currently Mikado and Masaomi, and thus considers herself a parasite. As a child, Anri was forced to witness her mother murder her abusive father with a katana called Saika, later revealed to be a copy of the original. Her inability to love negates Saika's "love" for humans and thus makes Anri able to control the blade. She seems to be a skilled swordswoman, being able to handle Saika with great skill. After defeating Haruna, she gains control over the "Saika-children" that Haruna created. After a talk with Celty, she decides to use this ability for the best of the city. Anri also becomes aware of Masaomi's identity as the leader of the Yellow Scarves, but does not understand why he has taken the position at first only later to find out it was for her and Mikado's sake.

Izaya Orihara

 * Orihara Izaya (折原 臨也)
 * Online Alias: Kanra (甘楽), Chrome (クロム) and "Nakura"
 * Izaya is an "info broker" who sells information to clientele who ask him for it. He is the main antagonist of the first half of the series, before gradually being supplanted by Kasane. A borderline sociopath and sadist, Izaya often claims to love all humans as a collective due to their unpredictable nature (with the exception of Shizuo Heiwajima due to him completely lacking this quality) and enjoys manipulating people in order to gauge their reactions. These situations often lead to injury and misery, forcing those involved to go to great lengths to rectify the situation or give up entirely. He is a master of parkour, having perfected his technique after years of fighting with Shizuo. He is also quite skilled with his flick-blade, as he is implied to be the only one capable of leaving numerous cuts on Shizuo (and his bartending suit) whenever they fight in the novels. In the anime, he shaves a gang member's head bald without the man noticing it. He is considered to be one of Ikebukuro's strongest men. Izaya's ultimate goal is to create a gang war between Mikado, Masaomi, and Anri, where only he remains as victor; he believes that Celty, as a dullahan, is basically a valkyrie and that if such a gang war were to take place, she would show him whether or not there is an afterlife.
 * In the past, Izaya attended Raira Academy with Shinra, Kadota, and Shizuo (whose life he made miserable since their mutual hateful rivalry began). At the beginning of the series, Izaya suspects that Mikado is the creator of Dollars (and is later proven to be correct) and knows the identities of the leaders of the three main forces in Ikebukuro. As a member of the Dollars, Izaya was also responsible for spreading the Dollar's website password thus recruiting many members (unbeknownst to Mikado) and has used his membership as an excuse to secretly keep Celty's head.
 * After a leave of absence after the Yellow Scarves arc, Izaya hijacks Masaomi's handle in order to manipulate Mikado whilst simultaneously using Akane Awakusu in a scheme to having the Awakusu Group kill off Shizuo. However, he was interrupted after Jinnai Yodogiri stabbed him as a warning for his interference. Upon making a recovery, Izaya assembles a small army composed of Namie Yagiri, Ran Izumii, Mikage Sharaku, Haruna Niekawa, Kisuke Adabashi, Slon, Kine, and the Dragon Zombie gang. At the climax of the events that follow, Izaya finally tries to kill Shizuo once and for all, and is nearly successful but is thwarted by Celty. In the ensuing fight, Izaya, while heavily injured, dares Shizuo to kill in front of multiple witnesses as a final attempt to prove that Shizuo is a monster. But Vorona stabs Izaya at the last second to prevent this outcome. However, before she can kill him, a stun grenade is thrown that allows a near-dead Izaya to escape. Izaya survives thanks to Celty partially healing him before Manami and Kine get him out of Ikebukuro. Though his fate remains a mystery to the residents of Ikebukuro at the start of Durarara!! SH, many assuming he had a role in the new chain of events. A wheelchair-bound Izaya admits to not be ready yet to return home as he continues his informant activities in another part of Japan. Izaya also appears in Shin Megami Tensei: Devil Survivor 2 as a playable character per downloadable content.

Shizuo Heiwajima

 * Heiwajima Shizuo (平和島 静雄)
 * A blonde man who is always seen wearing designer sunglasses and a bartender's suit. Although quiet and nondescript for the most part, he easily becomes angered, launching in uncontrollable rages and fighting with incredible strength which leads to broken bones and property damage. Despite this, Shizuo hates violence and wishes for a quiet and peaceful life. Despite his simple and unrefined fighting skills (namely his use of road signs, trash cans, and vending machines as weapons), he is considered to be the strongest fighter in the series. In the novels, Shinra describes Shizuo's ability as the naturally unlimited form of human strength, which he dubs "adrenaline power", that can give people superhuman strength in times of emergency. Because of this, Shizuo was often hospitalised due to the enormous strain on his body. In addition, Shizuo is capable of often superhuman parkour moves, a skill he obtained naturally from years of hunting down Izaya Orihara.
 * He is also a member of Dollars, although he left the group in Volume 6 after some members of the Dollars resorted to kidnapping (after being given the idea by Izaya) to settle a dispute with a rival gang. Shizuo works as a bodyguard in Ikebukuro for Tom, a debt collector and his senpai, being offered the job after he was fired as a bartender. Tom is one of the few people Shizuo doesn't get angry with, as well as the person who convinced Shizuo to bleach his hair (in order to scare away people who might try to fight him). He is close to and incredibly protective of his younger brother, Kasuka, who is a top idol under the show business name Yuuhei Hanejima and will become incredibly angry when strangers mention his name. Shizuo is also the only person who is able to read Kasuka's facial expressions and emotions. He is also a long-time friend of Celty, often having long conversations with her and even working with her on occasion.
 * Shizuo hates Izaya with a burning passion, becoming enraged at the mere sight of him, though he has stated that he wouldn't mind letting Izaya live as long as he stayed away from Ikebukuro. Before Izaya moved to Shinjuku, it's said that the pair would fight outside Sunshine 60 on a daily basis, only stopping when Izaya escaped or when Simon broke them up and forced them into his restaurant. Although he and Izaya Orihara are on bad terms, Shizuo is actually quite friendly with Izaya's younger sisters, Mairu and Kururi, who aren't afraid of him and may even prefer him to their brother.
 * His first and last name translates literally, and ironically, into "serene man" and "peaceful island" respectively. He also appears in Shin Megami Tensei: Devil Survivor 2 Record Breaker as a playable character per downloadable content.

Shinra Kishitani

 * Kishitani Shinra (岸谷 新羅)
 * Online Alias: Indoor Scholar (白面 書生)
 * A young underground doctor who lives with Celty and is also in love with her. He stays indoors mostly, and wears a white lab coat even when not working as a doctor. Shinra's father is also a doctor and Shinra has participated in surgeries with his father since childhood, most notably a vivisection on Celty. Shinra attended to the same primary school as Shizuo, and has since then been interested in his unlimited strength in times of anger. In fact, he rather enjoys it when Shizuo makes use of his strength and is amused by the fights between Shizuo and Izaya. He first met Izaya in middle school and has been friends with him ever since. Shinra is well-informed with news of Ikebukuro's underground, such as the location of Celty's head and the sword 'Saika' which allowed Celty's head to be severed from her body. Despite knowing this, he keeps a secret from Celty out of fear that he will lose her if she finds her head, as the head may have a different will than Celty herself. After Celty realizes Shinra had kept her head's location from her the entire time they have a falling out but have since reconciled. Shinra seems to have the "capacity" to tell what Celty is feeling, much to her surprise since she doesn't have a head to show her emotions. He has a great interest in unexplainable phenomena. His online screen name is revealed to Anri in one of the chat sequences.

He is revealed to be the Blue Squares current leader – but gives the position to Mikado for yet unknown reasons. Aoba seems to fear Mikado a little, since the incident in Volume 6, where Aoba is stabbed in the hand by a ballpoint pen he gave Mikado when they performed the agreement; Aoba also reveals that he and Izaya have underestimated Mikado and that neither of them fully understand his true character It is revealed in the more recent chapters that in his elementary school years, his older brother Ran Izumii abused him to amuse himself.  In return, Aoba set a fire in Ran's apartment for "revenge" and let Ran take the blame when the adults thought the fire started from cigarettes.

Van Crew
The Van Crew is a group of friends who travel around Ikebukuro in a van. Though seemingly harmless and amiable, in reality the group are vigilantes who formerly belonged to the Blue Squares, but defected and became part of the Dollars. They do good deeds around the city in the name of the Dollars. At one point, their van's car door was ripped off by Shizuo Heiwajima; Walker and Erika replaced the door, only to give the van a distinctive look by having different anime characters (most notably Miyuki Shiba from The Irregular at Magic High School) painted on the side. Notably, all of the characters' names are references to other authors affiliated with Dengeki Bunko, and Walker and Erika, being major otaku, frequently reference other novels in the imprint, such as Spice and Wolf, Sword Art Online, Toradora!, Black Bullet, and Bludgeoning Angel Dokuro-chan.

He quit the Blue Squares after finding out their leader kidnapped Saki Mikajima and subsequently rescued her along with his gang. His name is a reference to Kouhei Kadono. Though he is not an otaku, he is shown to be a fan of A Certain Magical Index.

He is another member of the Dollars.
