Red-Faced Anger

Girlfriend is a young woman with light skin and long, thick auburn hair. Two short locks of hair stick out of her head, one being much smaller than the other, and the shine on her hair resembles a skull. She wears a sleeveless red minidress and matching high heels. Her fingernails are painted red, as shown in her singing animations, where she points with both hands in the direction of the arrow note being hit, although sometimes this detail is not added. She normally sits with her legs crossed on a large gray speaker, with two smaller gray speakers laying beside the large one.

Girlfriend's regular appearance is that of a tall, relatively young-looking woman with long, thick auburn hair, a red dress and high heels as well as red painted nails. When in her Demon Form, Girlfriend gains a demon tail and purple skin, along with purple wings.

Girlfriend is portrayed as a young, mysterious woman. With a love for cherry soda and her boyfriend, she seems to be calm and collected in almost any situation, even in the face of death. Being a demon, she seemingly possesses a great deal of power, but she mostly chooses to hide it. She is always seen with Boyfriend at her side, courtesy of true love, as she genuinely loves him very much.

Like Boyfriend, Girlfriend lacks intelligence to the point of being unafraid of almost anything.[4] In general, she either does not realize when she is in danger or is confident that she can get out of such situations, which may also be due in part to the power she has. Her lack of intelligence can result in her getting into difficult situations, such as getting her hand stuck in peanut butter jugs and having to wait for hours for someone to help get it out. However, she is still capable of making smart decisions and knows what to do when dealing with taxes and facing death.

Girlfriend has been diagnosed with attention deficit hyperactivity disorder (ADHD) and autism.[8] The only individual she has been shown speaking to is Boyfriend. In Week 6 and Week 7, she does not speak at all, and she seems to barely acknowledge the opponent, if at all. Furthermore, she occasionally has poor object permanence. Girlfriend's talents as an artist and painter show that she is a creative individual. She has a poor concept of time, too, which is a common ADHD trait. She doesn't know very well how to handle money, either; she will normally make commissions (due to being an artist), but she will ask for 1 trillion dollars, or when she has to pay for a hamburger, she will pay less than what the hamburger costs.

Girlfriend has been described as being mean "in her own special way." She also likes to do immoral things, appearing to not care about the consequences of her actions as long as she gets what she wants. For instance, using her mother's limousine, she and Boyfriend hold up McDonald's drive-through slots as they hold the store hostage to get whatever food they want. Girlfriend is afraid of thunder and lightning.

Abilities Girlfriend is known to have multiple powerful abilities, but the details that can be inferred about them are limited. In the cutscene for Stress, it is shown that Girlfriend can make her eyes gleam red and her skin turn a light shade of purple, acting as a visual indicator of her using (or preparing to use) her demon powers. It has also been directly stated that Girlfriend can use demon magic, including some form of shapeshifting, as she is able to give herself a penis.[14] In Special Collab 1, Girlfriend demonstrates the ability to learn any language, and to give other people that knowledge, with a single tap.

Girlfriend can use her powers to protect herself, as well as other people, from any kind of damage, meaning she is somewhat invincible. In fact, she was apparently completely unharmed after getting run over by a truck[15][16] and falling from a plane, which her parents even knew would not be a problem for her.[17] Girlfriend is also capable of concealing her power level to a point where other people around her cannot sense it, such as Pump in Week 2. Additionally, an official Girlfriend shirt design shows bat wings in her shadow and a heart tail attached to the letter d in the text with her name,[19] both features of succubi. It was stated that the design reveals one of her future abilities.

Relationships Daddy Dearest Daddy Dearest, the father of Girlfriend, likely has good intentions with his daughter, but he is highly overprotective of her. He will not let her date whomever she wants and even tries to kill her boyfriend after he beats the father in a singing battle, which occurs after he stops the couple from having sex. He does not seem to care about how killing Boyfriend will affect his daughter.

Mommy Mearest Mommy Mearest is Girlfriend's mother. Like with Daddy Dearest, she is presumably well-intentioned with Girlfriend, but she also won't let her and Boyfriend date and is very overprotective. Mommy Mearest seems to be just as willing to try to kill Boyfriend as her husband is, not caring about the consequences that murdering him will have on Girlfriend. However, she does hand down clothes and iPhones to her daughter, showing that she cares about giving Girlfriend nice things. Girlfriend is willing to steal from her mother, as she and Boyfriend engage in the theft of Mommy Mearest's limousine in order to hold up the entire drive-through slot at McDonald's.[13] Senpai Senpai is likely someone whom Girlfriend has known for a long time as a love interest in her dating sim game. After Girlfriend is sent into the game, Senpai quickly falls in love with her after meeting her, believing her to be a "new fair maiden" who came "in search of true love." This makes sense as Senpai aims to win the player's heart, and the dating sim is Girlfriend's. He challenges Boyfriend to a singing battle to determine who can be with her. When he loses, he gets angry but is still determined to win Girlfriend over, threatening to castrate Boyfriend after getting freaky with Girlfriend.

Spirit Spirit had originally met Girlfriend during her 6th birthday party, where he fell in love with her. He then picked up a daisy for the ground to give it to Girlfriend, but before she could turn around, Daddy Dearest grabbed the little boy and sealed him inside of the dating sim, leaving him trapped in Senpai's body for 13 years.[22] Spirit recognizes Girlfriend after leaving Senpai's body, and it is evident that he is not happy to see her, as she is the reason her father trapped him in the first place. Because of his distorted sense of justice, Spirit considers it "only fair" to take Boyfriend and Girlfriend's bodies for himself in order to escape the game and get revenge on Girlfriend's father. He fails to do this, however, with Girlfriend and Boyfriend simply leaving Spirit behind in the game after her man beats the specter.

Tankman When Girlfriend and Boyfriend end up in the Tankman Battlefield, Tankman has his soldiers hold Girlfriend at gunpoint. However, Tankman and his men are bored, so they do not immediately kill her. Tankman is very rude to Girlfriend, insulting her appearance and being vulgar toward her and Boyfriend. When he orders his men to kill the couple after he loses twice, Girlfriend happily reveals her demon powers, showing her preparedness to fight back if necessary and that she isn't afraid of the Tankmen.
