MiCosmiC baby

In her introduction, Mico described herself as a baby and a royal diva. In contrast to her child-like voice and disposition when she normally talks, when she's singing she gives a serene and powerful performance befitting of a diva to be idolized.

She has long light purple hair ending in pink and a large ahoge with bright blue eyes.

Her YouTube channel was created on 4 August 2020 while her Twitter account was created in September. She debuted on YouTube on 14 November with a cover of [re:] project's song "Mou Ichido" and about one month later, on December 19, she started her first livestream.

• She calls her fans "Micotine chuudoku" (ミコチン中毒​​​​, lit. "Micotine addiction"), using a pun for "nicotine".

She also claims to speak telepathic language. ** Despite only having modest grasp of the languages, she can sing Indonesian and English language songs with perfect pronunciation. ** She has knowledge of the slang version of Indonesian that is rarely known by many people from overseas. One of her famous Indonesian slang phrases is "Bacot lu!"
