Elfuda (絵留札, Erufuda) is a light elf who traveled to this world for its exquisite fried potatoes: french fries. She loves them, claiming they are a sacred food from the gods. She met up with Naoe Tomoatsu, a Physical Therapist at the Smiley Boar who would help her lose the fat around her tummy so she could return home. After achieving this she does leave, however she quickly returns for those delicious french fries, re-gaining those lost pounds almost immediately. She decides to stay, now knowing she has a way to lose the pounds if necessary, something she originally thought to be impossible.

Kuroeda (黒枝, Kuroeda) is a Dark Elf who also traveled to this world. She has the ability to wield magic and control Golems, an ability that has the side effect of increasing her body mass, primarily around her butt, because of this she can only control a single golem (when Naoe Tomoatsu first meets up with her) She has an instant rivalry with Elfuda, them being from different Elf tribes.

Kuroeda is a veey curvy dark elf (light reddish-brown skin), with relatively long, wavy lilac hair, large red eyes, a distinctive mole below her right eye, pointed horizontal ears, thick thighs and a large ass bigger then elfuda and B-cups, and a shapely rear. She 172cm. She 26 years old.

Kuroeda is a professional on the job at the convenience store. She is also very determined, shown as she diligently practices the exercises she learned from Naoe to gain a tighter ass. She also gets into frequent arguments with Elfuda, demonstrating a dislike and rivalry due to them descending from opposing Elf tribes. However, over time they learn to tolerate each other's company for the sake of civility and the mutual goal of weight loss.

Kuroeda wishes to tone her massive "bubble butt" and bad posture from overworking her Earth job. Dark Elves can boost their magic by wearing special garments, which she can't fit into with her new gain of mass.
