She is fluent in English, and quite eccentric (due to being a half-American). Hosted a morning "news show"-esque 20-minute program on weekdays named "AsaCoco" (Morning Coco), which usually ended up creating absurd memes - such as Himemori Luna's English Corner, where the cute, childish princess constantly spews out obscenities, and most notably the drug "asacoco", a potent stimulant available to be delivered in a wide variety of forms ranging from needles to anal plugs.
Despite her wild antics, insane gags and frequent foul language (which often got her into trouble with YouTube), she is very eager to help her friends if need be and has a mature, big sister-like approach to troublesome situations (though usually laced with some of her personal brand of humor to break the seriousness if it's too much).
She was considered to have the second largest bust in hololive after Tsukumo Sana, even toppling Shirogane Noel's K-night cups. She was also significantly taller than the rest of the hololive girls (180 cm, compared with Omega Alpha, who is the second tallest at 175 cm without counting the gigantic Sana), especially the rest of the 4th generation (Kanata, Towa and Watame are all about 150 cm tall, Luna is the shortest at 140 cm, boosted to 150 cm with her shoes and crown).
She was the real-life roommate of Amane Kanata, and the apartment that they lived in together was called by other visiting hololive members as the "KanaCoco House". This means that they could (and had several times) make appearances on each other's streams.
She is in fact a big Ryuu ga Gotoku fangirl and has been known to play games of the series. In fact, her name and her title of "Chairwoman" ("会長" - Kaichou) are direct references to Kiryu Kazuma.
Kiryu Coco reached one million YouTube subscribers on February 17, 2021.
She announced her graduation from Hololive on June 8, 2021. Her final act was a live concert on July 1, 2021, which became one of the most viewed live streams in Hololive and VTuber history, reaching over 498,000 concurrent viewers.
