Cierra Runis

Cierra Runis (シエラ ルーニス) was a female Japanese / English / Chinese Virtual YouTuber. She was a member of the Virtual YouTuber club Overidea.

Personality
Cierra is described by fans as being intelligent, humble and laid-back. As a polyglot, she likes to switch between languages in her streams. Being a native English speaker, Cierra says she is barely understandable in Japanese and Chinese Mandarin, though she casually beats Obamama in foreign-language tongue twister games. On Twitter, Cierra does not take herself too seriously. She actively responds to questions, some of which are about how to learn a foreign language, or how be successful in school. She tries to offer advice while admitting she does not do so well in college either and has no idea what she is talking about.

Retirement
On 12 December 2019, Cierra posted a letter (available in 3 languages) saying she would take a break from being a Virtual YouTuber and put her focus on school work and personal aspirations. Her graduation stream aired on 14 December 2019.
