Name: Lango Stomach Gender: Male First person: I (俺 - rough, authoritative) The eldest son of the Stomach family. His younger siblings call him "Big Brother Lango." He possesses a cautious, forward-thinking mindset. Based on the philosophy of "winning over the wealthy to solidify the Stomach family's status and the Dark Confectionery business," he displays sharp management skills and judgment, regularly paying respects to the elite and attempting to secure connections by marrying off family members. Appearance: In his human form (mimicry), he wears all-black attire consisting of a jet-black long coat, an unbuttoned shirt, and distressed denim. He looks like a man who could be either a young adult or middle-aged, with his hair grown long only on the right side with red mesh at the tips. His true form is a gothic-style head resembling a goat or a demon, featuring a mouth membrane reminiscent of stained glass, glowing red eyes, and four long, horn-like protrusions, radiating immense pressure. The cane shared by the Stomach family can transform into a greatsword; he seems to keep several spares, as he always has a replacement ready even if one is destroyed.

Name: Grotta Stomach Gender: Female First person: I (私 - formal/confident) The eldest daughter of the Stomach family. She is Lango's younger sister and is called "Big Sister Grotta" by Nielb and the others. She is in charge of confectionery production at the Stomach Company. A natural battle maniac, she shows signs of enjoying combat. In fact, her fighting ability even in human form far exceeds that of an average Granute. Appearance: She prefers clothes that are easy to move in, wearing a black dress that exposes both shoulders, balanced by high-heeled boots. In her human form (mimicry), she appears as a tall, slender, and alluring beauty. When she reveals her Granute form for battle to crush enemies invading her territory, her fighting spirit is so intense it's as if she's shedding her very clothes. Looking at her entire true form, she evokes cephalopods like squid or octopus, featuring many suction-cup-like protrusions on her forearms and legs. Compared to Sita's monster form, she has a slender, white, feminine physique with smooth curves. Her purple legs are shaped like long boots, giving a seductive impression. Abilities: Her scythe increases in attack power when imbued with energy, and she can cleave distant opponents by firing shockwaves. Even if the blade shatters, it regenerates and repairs itself in a short time; she can also break it herself to use the fragments as makeshift projectiles. Despite her alluring aura, she is a militant who always carries the family cane, brandishing it to signal combat readiness at the slightest provocation, even toward her own siblings. When extended, the cane deploys a purple glowing blade at the tip, transforming into a large scythe.

Name: Nielb Stomach Gender: Male First person: I (僕 - soft, polite) The second son of the Stomach family. The twins, Sita and Jeep, call him "Big Brother Nielb." Appearance: He wears a steampunk-style long jacket and an ascot tie. In his human form (mimicry), he appears as a young man with short brown hair, almond-shaped eyes, and round glasses. Among the siblings, his makeup is the most understated. He wears orange nail polish, except for his ring finger, which is black. His true form features a gothic black head characterized by cornrows where the tips extend into several snake heads, and a mouth covered by an orange stained-glass-like membrane. The impression is reminiscent of piranhas or other carnivorous fish and snake-like reptiles. His weapon is a bow.

Name: Sita Stomach Gender: Female First person: I (俺 - rough, masculine) The second daughter of the Stomach family. Due to her formal attire with short pants, androgynous looks, and masculine first-person pronoun, she may look like a boy, but she is a biological female. A key characteristic is that she and her twin brother, Jeep, have swapped their appearances and gender presentations. At the Stomach Company, she manages procurement alongside Jeep. Appearance: She wears a double-breasted black formal suit with white frills on the sleeves, characterized by her male persona. She wears a sun-motif earring in her left ear. In her human form (mimicry), she matches her brother Jeep, appearing as an androgynous girl with long hair where the right half is white (opposite to Jeep, and slightly shorter than his). Her true form is based on white armor with cape-like fur added to both shoulders. The patterns on her chest are centered around circular shapes, giving a feminine impression, suggesting her human form's clothing is actually modeled after Jeep's monster form. She has a mouth-like biological organ on her head. In battle, she specializes in long-range attacks by transforming her cane into a short pistol, using light movements and coordination with Jeep to toy with opponents.

Name: Jeep Stomach Gender: Male First person: I (私 - soft, feminine) The third son of the Stomach family. Due to his dress-like attire, androgynous looks, and feminine first-person pronoun, he may look like a girl, but he is a biological male. A key characteristic is that he and his twin sister, Sita, have swapped their appearances and gender presentations. He wears a white dress with a black cape, characterized by his female persona. He wears a moon-motif earring in his right ear. In his human form (mimicry), he matches his sister Sita, appearing as an androgynous boy with long hair where the left half is white (opposite to Sita, and even longer than hers). He carries the family cane hanging near his left hip, slung over his right shoulder. His true form is a wolf-like figure clad in white armor with a light blue base. Claw-shaped pauldrons are added to both shoulders, and the chest patterns are centered around sharp angles, giving a masculine design. This suggests his human form's clothing is actually modeled after Sita's monster form. He has a mouth-like biological organ on his head. His cane can transform into twin short swords. Usually, it is a machete-like short sword, but by pulling out the hilt, he can dual-wield it with a knife-like dagger. He specializes in continuous attacks utilizing his small stature, working in perfect sync with Sita to surely finish off opponents.
