Usada, or Rabi~en~Rose, is revealed to the viewer to be Dejiko's rival. Her nickname may be a play on a number of things. "Rabi~en~Rose" may be a play on the common French saying "La Vie en Rose" which means "life in rose-pink". The Japanese expression "spend a life in rose-pink" means to spend a life without any worries. "Rabi" which resembles the English word "rabbit." replaced "La vie" to form a pun to mean "Rabbit in life without worries," which suggests her personality. Her original name is Hikaru Usada, which resembles Hikaru Utada (best known in the West for her theme songs for the Kingdom Hearts series) but that was officially commented as a mere coincidence since the story and names were decided before Hikaru Utada's debut in Japan. Her "Usada" surname also is a pun, as the "Usa" part is a shortening of the word "usagi", which means "rabbit" in Japanese. In the original anime, she is seen as a normal girl who uses dice to transform into her bunnygirl outfit: a pink, white and red dress with large white rabbit ears and a large round cotton tail. Her parents left her to live on her own in an attempt to help her become an idol. Rabi~en~Rose does not end her sentences with a rabbit sound (typically pyo in anime) and is the only character with kemonomimi animal traits in the Di Gi Charat franchise not to do so. (source: wikipedia) She is very competitive and always is trying to start something with Dejiko. In some of the manga stories, however, it is shown tthat she really just wants to be her friend, and this is hinted at in various ways, often ending in a comedic gesture.
At the beginning of the story it is explained that Puchiko, also known as Capuccino, is Dejiko's five year old sidekick and is a catgirl. Her relationship to Dejiko is not explained in the original series, but Gema states that she is a princess in the Di Gi Charat Movie and it is seen that she lives with Dejiko in the castle in Panyo Panyo Di Gi Charat. According to Di Gi Charat Complete 2002, Dejiko saved her by pulling her out of a hole, and so Puchiko followed Dejiko to thank her. Although in Winter Garden, it said that Puchiko is Dejiko's sister and share the same parents. Puchiko is quiet (but when she does speak she has unexpected sharp tongue) and has a Type B personality. She has the ability to use an eye-beam similar to Dejiko's but is often too docile to conjure the aggression required to perform such a feat. This has caused many things to come out of her eyes, including sludge, when she attempts to use it. Puchiko has brown hair and dark brown eyes. She wears a schoolgirl-type uniform plus cat bells in her hair, though they are much smaller than Dejiko's. She wears orange boots, cat ears and tail. She ends each sentence with nyu.
