The name "Domo" was acquired during the second episode of his show in which a TV announcer said, "dōmo, konnichiwa", which is a greeting meaning something along the lines of, "Well, hello there!", but which can also be interpreted as "Hello, Domo!", and thus is a convenient pun. The
kun suffix on "Domo-kun," the name used to describe the character in the Japanese versions, is a
Japanese honorific often used with young males.
Domo, the main character, is described as "a strange creature that hatched from an egg." Domo's favorite food is Japanese-style meat and
potato stew, and he has a strong dislike for
apples, due to an unexplained mystery in his
DNA. Domo can only communicate via producing a low-pitched noise which sounds somewhat like his own name, but other characters appear to understand him. Domo-kun is known to
pass gas repeatedly when nervous or upset.
Domo lives in an underground cave with
Mr. Usaji, known in
Japanese-language versions as Usajii, a
portmanteau of the words usagi , (rabbit), and jii (old man,
grandpa). Mr. Usaji is a wise old rabbit who loves to watch television and drink astringent green tea. Mr. Usaji is not into any "new" materials, and does not own a
telephone. In terms of fashion, Mr. Usaji focuses on materials instead of shapes. Mr. Usaji's favorite food is
carrots, and his least favorite food is "something that is meaningless."
Also in the cave live two bats, a mother named
Maya and her child
Mario. Maya has a drinking problem; her favorite foods are seasonal while her least favorite food is, ironically, alcohol. Mario's favorite food is Japanese-style tomato
spaghetti, while his least favorite food is
shiitake mushrooms.
The other main character in the shorts is a weasel girl named
Tashanna. Tashanna, 17 years old, is a weasel who aspires to be a fashion stylist or model in
Tokyo and is always using technology (televisions, mobile phones, and cameras). In English Tashanna has a "weaselly accent" and ends her sentences with "
y"s. In the Japanese version, she ends her sentences with "chi". According to the English site, she is also looking for a boyfriend. Tashanna's favorite food is
apricot and
mint tarts, and her least favorite food is
sea urchin. The Japanese name originates from the word "
multichannel" of digital broadcasting.
Bear Boy, also known as
A Little Bear, is one of Domo's friends from the neighborhood; the timid cub enjoys playing
baseball.
Hee and Haw (Flower Two) are pixie twins from a flower. Domo is the only individual who can see them.
The Fox Trio consists of
Esther, Brother Fox, and
Fox Boy. Esther, the youngest member, enjoys producing
crocodile tears, plotting schemes, and causing havoc. Brother Fox, the eldest member, dutifully cares for his youngest siblings and feels upset when referred to as "short-legged". Fox Boy, having a quiet demeanor, converses with Domo and Bear Boy and prefers to read.
Hungry Bear, a large and powerful bear, feels too hungry to take advantage of his strength.The Ghost randomly appears and disappears.
