Characters
A 19-year-old boy, 2.13m tall. He has short, cyan-blue hair styled in spiky, messy tufts that go in different directions, often partially covered by his signature backward-facing red and blue cap. He dresses in a simple, urban rap style: backward red and blue cap, white t-shirt with a red prohibition symbol in the center, long, slightly baggy light blue jeans, and red sneakers.
Girlfriend is pale-skinned with long, wavy, reddish-brown hair. She is Boyfriend's main motivation and often sits on a giant speaker to cheer for him during rap battles. Outfit: A sleeveless red mini-dress and matching high heels. Secret: She is a pure-blooded demon, though she maintains a human appearance. (She is calm, cheerful, and blindly trusts in Boyfriend's talent. She always speaks in a refined and elegant tone compared to Boyfriend).
Nene and Darnell's best friend. Pico is an orange-haired young man, a mercenary-for-hire, and one of the most iconic characters. He wears a green t-shirt, brown pants, and orange sneakers. He always carries a submachine gun (MAC-10) in one hand and a microphone in the other. Hired by Girlfriend's father (Daddy Dearest) to eliminate Boyfriend, he decides to spare his life upon discovering they are exes. He is an expert marksman and an extremely fast, aggressive rapper. He is rude, pragmatic, and suffers from PTSD due to past school trauma. He speaks in a coarse, sarcastic tone, rarely being kind unless dealing with a stranger. He is arrogant and superficial.
A former rock star and a pure demon. He is the husband of Mommy Mearest and the overprotective father of Girlfriend, determined to humiliate or eliminate Boyfriend for being unworthy of dating his daughter. He has lavender-colored skin, black eyes with glowing red pupils, and grayish-lilac hair styled like horns. He dresses extravagantly in an open black suit jacket with no shirt (exposing his chest), black pants with a gold buckle belt, and a silver watch. (Extremely arrogant, controlling, Machiavellian, and ruthless).
Girlfriend's mother and Daddy Dearest's wife. Like her family, she has purple skin, black eyes with glowing red pupils, and long brown hair with spiky tips. She wears a tight, short red dress under a black jacket, high-heeled boots, gold hoop earrings, and matching bracelets. She is known for her black lipstick, long sharp red nails, and a visible garter on her left leg. She presents herself as a seductive, glamorous, and extremely dangerous woman, ready to eliminate anyone who tries to get close to her daughter. She is a pop superstar who radiates immense confidence. She challenges Boyfriend not out of pure hatred, but for twisted artistic pride and to humiliate him musically. She shows an extremely affectionate, daring, and synchronized attitude with her husband, sharing a high-status "power couple" dynamic.
Designed with a 16/32-bit retro aesthetic that mimics classic dating sims. He wears a light blue button-down shirt, a loosened pink tie, and gray trousers. He has light brown hair swept to one side, permanently flushed cheeks, and a constant glimmer in his eyes. At first, he appears extremely polite, gentlemanly, charming, and self-confident. He believes he is the center of attention and immediately assumes that any girl (including Girlfriend) would fall for him. His kindness completely vanishes when he loses a rap battle. He uses formal, polite, and poetic language to flirt.
