Sakura Dormitory residents

Sorata Kanda (神田 空太, Kanda Sorata)

Voiced by: Yoshitsugu Matsuoka (Japanese); Greg Ayres^[2] (English)

Sorata is the male protagonist of the story. He is a second-year (later third year) student of Suiko, who lives in room 101 of Sakura Dormitory. He was kicked out of the regular dorms after he chose not to give up a stray cat he found (he cannot resist taking in stray cats, and he ends up keeping seven of them in his room). As many of the Sakura Dormitory residents have outstanding grades and art skills, he often feels plain and normal among them.

Chihiro, the dorm supervisor, chooses him to take care of Mashiro, the "pet girl" referenced in the title, and he is, understandably, reluctant to do so but ends up getting used to it. At the end of the thirteenth novel, he confesses to Mashiro. Sorata decides to become a computer game designer, but his game proposal to a famous computer game company is repeatedly turned down. In the sixth novel, he decides to make a game on his own. A major plot of the story is how his personality and self-expectation evolves.

Mashiro Shiina (椎名 ましろ, Shiina Mashiro)

Voiced by: Ai Kayano (Japanese); Caitlynn French^[2] (English)

Mashiro is the female protagonist of the story. She is the resident of room 202, as well as a world famous artist who transferred into Suiko as a second-year to learn how to draw manga. Although her artwork is widely admired, she knows nothing other than drawing and has an extreme lack of common sense and living ability. Due to this, Sorata is forced to "adopt" Mashiro and help her out with the basic tasks of everyday life that everyone else takes for granted; he even has to pick out underwear for her to wear or she will go out without them. Her focus on what she wants to do, draw manga, awes Sorata and inspires him. She has very bad grades, since she cannot pay attention in class, but she can still pass the make-up exams by photographically memorizing all of the answers with her art talent. In the third novel, Mashiro starts to develop feelings for Sorata and she even claims that she cannot live without him. According to Mashiro, she plans to live in Sorata's house and work as a manga artist after graduation.

Nanami Aoyama (青山 七海, Aoyama Nanami)

Voiced by: Mariko Nakatsu (Japanese); Christina Kelly^[2] (English)

Nanami is Sorata's classmate, who later moves into Sakura Dormitory's room 203. Although she is harsh to Sorata, she actually has a crush on him, and everyone aside from Sorata has noticed this. She left her home to become a voice actress without her parents' consent, and has to live on her own. After she finds herself low on money, as well as noticing that Sorata and Mashiro are becoming close, she chooses to move into Sakura Dormitory, which is more affordable than standard student housing. She meets Sorata's mother in the fifth novel and earns the latter's admiration. Sorata's mother even tells him that she would welcome Nanami as a daughter-in-law. In the sixth novel, she fails her voice actor tryout and decides to reconcile with her parents before deciding her next step. She is able to convince her parents to let her continue her VA studies and returns to Sakura Dormitory for her final year of high school. She speaks with a Kansai dialect when she is angry or flustered.

Misaki Kamiigusa (上井草 美咲, Kamiigusa Misaki)

Voiced by: Natsumi Takamori (Japanese); Luci Christian^[2] (English)

Misaki is the resident of room 201, a third-year-student of Suiko who later attends Suimei University of the Arts. She is very outgoing and optimistic and Sorata often refers to her as an "alien". She has very good grades and is very good at drawing, but the school decided to send her to Sakura Dormitory because she pays too much attention to drawing anime and manga. She is very good at animation and can handle the work required to make one without help from others. She has already sold an animation to a famous publishing company and made enough money off of it to live comfortably for the rest of her life. She has feelings for Jin, and openly expresses them, but Jin turns a blind eye to this and dates many other girls, which makes her very depressed. The two finally become a couple during the fifth novel. In the sixth novel, she registers their marriage without asking Jin, making them officially husband and wife; her new name is Misaki Mitaka (三鷹 美咲, Mitaka Misaki). She moves out of Sakurasou after graduating and moves into the house next door which has a recording studio in the basement.

Jin Mitaka (三鷹 仁, Mitaka Jin)

Voiced by: Takahiro Sakurai (Japanese); Scott Gibbs^[2] (English)

Jin is the resident of room 103 and a third-year student of Suiko. He is Misaki's childhood friend and has feelings for her, but he feels he is not good enough for her, so he ends up becoming a playboy. He has dated several girls, including Misaki's elder sister, but in the end he breaks up with all of them. He finally goes out with Misaki during the fifth novel. He wants to become a playwright/script writer worthy of her artistic talents, and chooses to attend a university in Ōsaka to achieve his goal. To pacify Misaki, he gives her a marriage registration form with his signature as a warranty that he will return, but Misaki signs and turns it in on the same day that he leaves for Ōsaka, which makes them officially married.

Ryūnosuke Akasaka (赤坂 龍之介, Akasaka Ryūnosuke)

Voiced by: Yui Horie (Japanese); Blake Shepard^[2] (English)

Ryūnosuke is the resident of room 102. Ryūnosuke is a second-year student of Suiko. He is a hikikomori who rarely leaves his room, and usually communicates with others by text message or e-mail. To reduce the need to personally communicate with others, he has written the "Maid" AI program, which responds to messages in his place. He is an expert of computer programming, and gives Sorata much useful advice about his computer game. According to Ryūnosuke, his ultimate goal is to have Maid become a real human. He has gynophobia, and will pass out when a girl touches him. This affliction becomes more severe after Rita falls in love with him and kisses him on the cheek. His favorite food is tomatoes, saying that he trusts tomatoes more than anything in the world. He is nicknamed "Dragon" by Misaki. During his middle school years, Ryūnosuke was a part of a game project made by his friends, but his intelligence was such that the others could not keep up with him and sidelined him from the project, resulting in Ryūnosuke becoming wary of forming friendship with anyone (including everyone in Sakura Dormitory). However, after a call from Rita, he manages to get over his fear of friendship and help his friends prevent Sakura Dormitory from being demolished.

Maid (メイド, Meido)

Voiced by: Yui Horie (Japanese); Holly Segarra^[2] (English)

Maid is Ryūnosuke's artificial intelligence program. Originally, Ryūnosuke designed Maid to filter and automatically reply to his cellphone messages and e-mails to save him time. However, Ryūnosuke keeps expanding Maid's AI ability. Maid is now capable of blocking and replying to a message or e-mail by her own preference, using new words she has recently learned from other messages, e-mails, or the Internet in the reply, anticipating people's emotions, writing computer or cellphone viruses and sending them out by herself, hacking into Suiko's computer network to steal information and even giving Sorata solid advice about his computer game program. The only way to distinguish Maid's messages from those of a human is that she replies too quickly. Ryūnosuke lets Maid enter a social networking service, with most people who meet her not realizing she is an AI program. According to Ryūnosuke, his ultimate goal is to give Maid an artificial body and become a real human.

As running the Maid program requires a lot of hard drive space and RAM, Ryūnosuke is forced to keep her working in the high standard server set in room 102 of the Sakura Dormitory, while giving orders and receiving the results via the Internet when he is absent from the room. On the computer, Maid is shown as a 3D model (designed by Misaki) on the bottom right corner of the screen, and will be shown using various tools and stationary depending on her current work. Maid appears to have a crush on Ryūnosuke, although it is unknown whether she has developed the feelings herself or if it is simply a part of her program design. After Rita falls in love with Ryūnosuke and kisses him, Maid starts a fight with her over the Internet since Ryūnosuke constantly lets Maid handle Rita's love letters and e-mails. Maid even asks Sorata to go to England and help her eliminate Rita.

Chihiro Sengoku (千石 千尋, Sengoku Chihiro)

Voiced by: Megumi Toyoguchi (Japanese); Olivia Swasey^[2] (English)

Chihiro is an art teacher at Suiko and the dorm supervisor of Sakurasou. She is Mashiro's cousin and arranged for her transfer to Suiko. She once wanted to become a professional artist and was a conscientious student while attending Suiko herself. Unfortunately her dreams did not come true for unknown reasons and she became an art teacher. Despite being a teacher, she often gives Sorata improper advice. Perhaps due to her disappointment, she has become cynical and lazy, often foisting undesired tasks, such as looking after Mashiro, on the unfortunate Sorata. She appears to only be interested in drinking and trying to find a man.

Rita Ainsworth (リタ・エインワーズ, Rita Einwāzu)

Voiced by: Ayako Kawasumi (Japanese); Skyler Sinclair^[2] (English)

Rita was Mashiro's roommate and caretaker when Mashiro lived in England. She became jealous of Mashiro's talent, and so advised Mashiro to draw manga hoping to see her fail, but later she regrets her actions and comes to Japan to bring Mashiro back to England. After realizing Mashiro's determination, she gives up and returns to England with Mashiro's father and starts studying art again. Even though he is cold to her, she falls in love with Ryūnosuke and kisses him on the cheek before leaving, which makes him pass out. Afterwards he ignores her and has his Maid AI handle all of her e-mails, which only fortifies her resolve. In the fifth novel, she visits Japan again to give Ryūnosuke Valentine's Day chocolate, and manages to kiss him on the lips, which makes him pass out again. She moves into Sakurasou after Nanami leaves.

However, she still dislikes Nanami because not only can she take care of herself, she also helped Sorata and Yūko's mother with many of the household chores during her stay at their home, garnering praise from their mother.
