|“||I was born to become an idol! Nice to meet you!||”|
|— Roco Handa, Online Character Profile|
Roco is a positive girl who believes that she was born to be an idol, and she dreams of becoming a great artist using her own art style. Like many artists, Roco has weird habits that are hard for others to understand. The most apparent one would be her way of speaking--Roco likes to fill her sentences with English words, sometimes to the point of being almost impossible to understand. She prefers to use them even if they're not that common in usual speech. She will quickly correct herself if she accidentally catches herself not using a loanword, even though her English skills are not that good and she still occasionally requires a dictionary. When she's really concentrated or surprised, she’ll speak in a normal way, suggesting that she's doing this on purpose.
Roco’s artist skill covers a really wide range; she can draw, sculpt, design, create her own clothes, and even build a stage set by herself. Although, like many artists, her creative sense is hard to understand for normal people. In fact, most of the time they don’t even have any idea what she has created. She also likes to act as soon as she has inspired, regardless of place and time. She'll also redesign objects on the spur of the moment (or in her own words "roconize"), whether it’s a borrowed costume, a Drama’s set, or the office itself. Roco also likes to keep up with popular fashion, often changing her accessories from card to card. However, she always keeps her yellow headphones with her all the time and when she has to take them off, she gives them to the Producer while telling him not to lose them since they're important to her.
Although Roco always acts confident, deep down, she actually feels lonely, since her weird quirks and her hard-to-understand artistic sense often alienates her from the other idols. Roco is very happy when someone praises her art and she also shows her weak side to the Producer from time to time.
- Roco refers to herself as Roco, written in katakana characters.
- Roco is often paired with Subaru Nagayoshi, most likely because Subaru likes to drag Roco to play outside despite her protest.
- While Roco always refers to herself as "Roco" and it’s also written on her card name and profile, some fans like to think that her name is actually Handa Michiko. This comes from the Spring Music Festival event where Takane Shijou calls Roco by her full name (伴田路子) and Roco replies with “Please don’t call Roco by her real name. Real name, not full name, real name." Couple that with the fact that her given name can be read as Michiko, a fan theory was born.
