"A girl who traveled from a different universe. She has hyper curiosity and manages to reach out to all sorts of things. Her trademark pigtails float due to some sort of supernatural power." Aki Rosenthal (nicknamed Akirose) belongs to the Hololive 1st Generation. She debuted alongside Natsuiro Matsuri and Shirakami Fubuki. Because she didn't have pc nor laptop at beginning, and only had a phone provided by Cover, Aki used Mirrativ for her debut stream.

Aki is half-elf half-siren from another dimension, with her mother being a siren and her father an elf. Aki Rosenthal is not actually her real name, but a name given to her by Yagoo so she would have an understandable and easily pronounceable name here on Earth.

Aki's most distinctive trait are her floating twintails, which are connected to another dimension via mysterious power. She is also able to produce a wild variety of objects and materials from between her thighs, the nature of this 'portal' is just as mysterious as her twintails.

Aki's content used to be mostly focused on ASMR alongside some online games and live-cooking, but with her demonetization in December and later remonetization, she has been doing ASMR less often. She still does ASMR sometimes and she often has unique ideas, such as dish washing ASMR and gaming chair building ASMR. Aki also does binaural ASMR music. Birthdates are the debut dates, since Idols are forever as young as they want :)
