Erika Karisawa (狩沢 絵理華, Karisawa Erika) is a manga reader and "fujoshi". She has brown eyes and brown hair that is pulled back into a braid at the back of her head, with two pieces of her hair hanging freely infront of her ears. Erika is in the Dollars Gang, and can usually be found driving around the city with her friends Walker, Saburo and Kadota. She and Walker are both otakus (people obsessed with anime and manga.)
She normally wears a black hat and a matching dress with a long skirt, with dark brown eyes and hair with two bangs on either side of her head, reaching to her chin. However, when her hat is off, it is shown that her hair is much longer, being in a braid and tied to the back of her head. It is also shown that she often carries a book bag slung over her shoulder, possibly filled with manga novels of many kinds.
It is implied that she possesses a dark past like Walker. Kyohei is presumed to have rescued her, explaining why she remains so loyal to him.
She and Walker are usually seen together. She is equally enthusiastic about manga or novel inspired torture as he. Her personality can come off as hyperactive and strange, but she proves in Episode 20 that she is calm and can reason with people, although she goes right back to being her normal otaku self immediately after talking. In the later episodes, she and Walker were asked to remain in the van during the invasion of the Yellow Scarves, the reason being that they "stand out too much". She can be seen with Walker in the hospital beside Masaomi, with her head resting on his shoulder. In the manga, Kida explains to Mikado that she and Walker are a bit peculiar, but good people. Like Izaya, she calls Kadota "Dotachin". She is a member of the anonymous online gang Dollars and is also a member of Kadota's gang. In some episodes it is shown that she is a big Yaoi fan whenever she sees Izaya and Shizuo fighting. Erika is convinced that Shizuo and Izaya are lovers, despite (or because of) their constant fighting. Erika is also shown to support Kadota and Chikage together as of Volume 6 of the Light Novels.
Erika and Walker have been seen to be skilled in both mental and physical torture, displayed whenever the two need to extract information from someone. During interrogation, the torture they conduct is usually based on themes from a manga or anime series of the victim's choosing, and is usually very violent as evidenced by Saburo telling them not to use gasoline in the car in episode 06. In the light novels, one person chose the series Kuroshitsuji as the theme, and the two of them tried to tattoo an upside down pentagram into the man's eye that is similar to the ones found on both of the main characters.
Dollars and Mika Harima ArcEditShe and Walker meet Mikado and they tell him about the large stack of manga they bought. A couple days later she and Walker meet up with Kyohei who was putting tiles on a bathroom wall. Erika suggests to go ahead and eat at Russia Sushi. As they leave, Kyohei gets a text from Kazutano which everyone ignores.
After eating at Russia Sushi she and the others go to Kazutano's apartment to find the place is a wreck. Saburo deduces that he was kidnapped much to everyone's distress. As the group searches for Kazutano, she suggests to call him. Kyohei does so but hears Izaya on the other end informing them of one of the kidnappers locations.
They go to the place to find the kidnapper sleeping. Erika and Walker suggest using manga torture to wake him up but Kyohei tells them no on the grounds that they might accidentally kill him. Once Kyohei manages to trick the other kidnappers into revealing their location, Erika is seen celebrating with the rest of her group.. Later she is in Saburo's car when they got to the kidnappers. When the kidnappers runn off without Kazutano because of the Black Rider Erika jumps back in the car and they chase them down. One gets away but they manage to corner the last one. In the moring, since the kidnapper refuses to talk, Walker and Erika tell Saburo that they can take care of him.Saburo gets out telling them not to use gasoline again. Then Erika and Walker pull out several manga books and tell the kidnapper to choose one. The kidnapper, becoming increasingly distrubed at the nature of the different books he sees, finally picks "Black Butler." Erika holds him down so Walker can use the soldering gun on the guys eye. But Kyohei stops them once the kidnapper agrees to talk.
The next day she is looking around town wanting to give walker's phone back to him after he left it in a cafe. She asks Simon but he said he hasn't seen him. Shiri walks up telling her to sign her book that is labeled Missing stuff. Later she finds and dances with Walker.
A day later she is with Saburo, Kyohei,and Walker when a guy accidentally flicks a pebble at Saburo's car, scratching it. Saburo drives full speed at the guy but stops just in time to avoid running over Mika Harima. As she explains the situation to them, they get a text to participate in the dollar's meeting. Erika and the others attend the gathering and marvel at how large the dollars had become and were even more surprised as Celty rode down from one of the buildings.
Saika ArcEditErika and the others were driving around town at night with Erika teasing Walker about the book he was reading. Kyohei asks why Walker was getting so worked up and she explains it's because the book was something Walker himself had self published. Kyohei then tells them to focus on finding the slasher. Erika is with the others as they save Anri from one of the supposed "Slashers." Saburo hits him with his van but he simply gets back up and tries to attack Anri again.. Suddenly Shizuo and Celty come in and incapacitate him via crushing him with Saburo's van door (much to his distress). When Shizuo leaves, mentioning his intent to kill Izaya, Erika says that Shizuo likes Izaya which everyone immediately denies.
The next day, after interrogating him they released that slasher since the guy said he dosen't remember anything.

It is revealed that Erika was with Kyohei's crew when they were still part of the Blue Sqaures. However, they betray the group by saving Saki. In the present she is at the Russia Sushi eating. Masaomi walks up and tells them that he needs to talk to them in one of the privite rooms.
Masaomi askes them about the blue squares but she and walker don't give him any straight answers. As the talking gets more intense she gets scared when Dennis throws a knife in the room telling them that their talk is scareing the custormers.
Not long after, Erikaand Walker are left out in the war between the Dollars and Yellow Scarves since they'll stand out too much. They are last seen sleeping in Masaomi's hospital room.
Mikado and Anri turn to Erika and Walker for help in regards to giving someone a tour of ikebukuro since neither of them are very good at showing people around. Erika and Walker try to give them some good tops and even make a list of some of the more interesting (to them) sites around the city but decide that it would be simpler to just come with them. After singing some Karaoke, the four of them part. The next day, Erika, Walker and Kyohei save Mairu and Kururi from some Toromaru members and call in Saburo to pick them up.
Eventually, they start getting chased by Toromaru and the six of them eventually pick up Mikado, Anri , and Aoba as well.

They watch as Ruri and Igor beat up the Toromaru members that were chasing them. Afterwards, Erika along with Celty, Emilia , Anri, and Mika assisst in the cooking for the hotpot party at the end. The color illustrations rate the girl's cooking skills with Erika scoring an even 70.

After the fighting dies down, Erika starts asking Anri about Saika and even begins trying to search Anri's person for where she keeps Saika hidden.
Kyohei manages to pull her off of Anri who decides to go look for Mikado. Later, Erika starts giggling about something and Kyohei asks her why.

Main Article: Kyohei Kadota
Erika and Walker have both been with Kyohei and his group for several years and are extremely loyal to him. While in the blue squares, they immediately defected from the gang with Kyohei without question despite the possibility of revenge from other members. When Kyohei was beaten into a coma in Volume 10, she immediately dropped everything to see him in the hospital. During her stay, she swears vengeance while smiling maliciously. In the Durarara!! side stories it is implied that she has feelings for Kyohei but these are never elaborated on or addressed in the main series.

Erika tries to get Anri to take up cosplaying and even convinces her to try on a few outfits but has very little success. When she learned that Kadota was attacked she rushed to the hospital with Anri, who stayed with her the whole time.
