Panyo Panyo Di Gi Charat is an animation created by Mad House. it revovles around an 8-years-old Dejiko, Puchiko and her friends; Meek Charat and Rinna Charat who set off to bring happiness to the citizens of planet Di Gi Charat, while Piyoko and Deji Devil try to stop them.
While Princess Dejiko is reading a book, she realizes that she "needs" to help people all over the world. Dejiko takes Puchiko with her and tries to leave the castle, but Dejiko's tutor interrupts because it is her study time. Dejiko uses her laser eye beam and attempts to escape the castle numerous times, each time being thwarted by traps and gadgets set up by the tutor. Eventually, the duo are caught. A very petulant Dejiko stands her ground, and the tutor finally relents and lets Dejiko and Puchiko go outside the castle grounds, on the condition that they take Gema with them as a chaperon.
In the following episode the trio arrive at the popular Rinna's Cake Shop. The shop is closed, and people are in line in front of the shop, waiting patiently for it to open. Dejiko, Puchiko, and Gema forcibly enter the shop and find that the owner, Rinna, is asleep. Dejiko decides that she and her friends will make the cakes for Rinna while she is sleeping. Everything seems to be okay until the cakes fall in the oven. When Dejiko laments, Rinna suddenly awakens to make the cakes. As she bakes, she sings that the missing ingredient in Dejiko's cake recipe was love and the anticipation of seeing her customers' happy faces, which she calls "baking powder of the heart." Confident again, Dejiko says that she will help Rinna make the day's cakes, but Rinna is asleep again. Later on, Rinna decides to close the cake shop to take an extended break and join Dejiko and her friends.
A cat appears and jumps on Dejiko's head. A girl named Meek, appears in pursuit of the cat, but Dejiko mistakes Meek for the devil. Later, at a fish shop, where the group again runs into Meek, the cat appears and steals some fish. Meek, this time with the help of Dejiko and friends, tries again to catch the cat, but fails once more. When it appears that the cat is cornered, her kittens emerge from a hole in the wall. Meek finally realizes that the cat only wanted to feed its family and blithely decides to blame Dejiko and friends for stealing the fish. Meek joins the merry band not long after.

Rinna - りんな Rinna is the owner of her own cake shop.

Piyoko - ぴよこ (also known as Pyocola Analogue III ) A young girl who works for Deji Devil. Apparently, she is the leader of the Black Gema Gema Gang, despite being only six years old. She addresses Deji Devil as "Deji Devil-sama" ("Lord Deji Devil"; in the dub, she refers to him as "Boss"), but according to her character profile, she has little actual respect for him. Dejiko and company do not treat her or Deji Devil as a threat, going so far as to refer to Piyoko as "Piyoko-chan" as if they were close friends. Piyoko ends her sentences with "-pyo".

Deji Devil - デジデビル Deji Devil's mission is apparently "to make everyone on Di Gi Charat unhappy". Thus, his and Dejiko's quests are somewhat mutually exclusive. Aside from his wings and cape, his body has no substance, therefore he is able to pass through objects. Interestingly, he supposedly is afraid of ghosts. He ends his sentences with "-devi". In one of the final episodes, it is revealed the Deji Devil can transform into a large pink, flying, panda-like being referred to as "The King of Demons". In this "King of Demons" form, he is no more solid than he is ordinarily; however, he gains the ability to fire lasers from his mouth. According to him, he doesn't usually use this form because "people might start to expect it".

Gema - ゲマ Gema is a perfectly round, floating, yellow creature who accompanies Dejiko everywhere as a chaperon. According to his character profile page, most of Gema's data is unknown (including what species he is). He bears a slight resemblance to Pac-Man; the most notable feature about him is his apparently upside down face.
