The two and their friends Meek and Rinna set off to bring happiness to the citizens of planet Di Gi Charat, while Piyoko and Deji Devil try to stop them.

Dejiko, Puchiko, and Gema forcibly enter the shop and find that the owner, Rinna, is asleep.

Later on, Rinna decides to close the cake shop to take an extended break and join Dejiko and her friends.

After reading a book about a famous philanthropist, she made a vow to bring happiness to every person who lives on Di Gi Charat.

She wears a white hat shaped like cat ears, with a pair of gold bells on it.

In episode 2, the townspeople claim that she makes the most delicious cakes on the planet; however, they have no idea when her shop will open, as Rinna has a tendency to fall asleep without warning.

Piyoko - ぴよこ (also known as Pyocola Analogue III ) A young girl who works for Deji Devil.

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.

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.

He bears a slight resemblance to Pac-Man; the most notable feature about him is his apparently upside down face.
