Kumagai Chisato

This name is written using the Japanese name format; the family name is Kumagai.

Kumagai Chisato (熊谷ちさと), also known as Beatani (べあたに), was a female independent Japanese Virtual YouTuber.

Previously a 24 year-old average office worker, she was thrown and locked into the internet by her sister. Chisato describes her current job as "gatekeeper of the Internet."

Beatani was on hiatus from May 11th 2022 to Aug 6th 2022. Some time after her hiatus, she announced that she would hold her last stream on Nov 14th 2022.

Personality
Beatani can be very straightforward in the way she presents her opinions. She tends to engage in topics with chat regardless of how unusual they are. Sometimes, Beatani will deliberately introduce an unusual topic on her own, and go into unnecessary detail about it.

Beatani can be easily distracted during stream activities that require her full attention (for example, leaving her drawing unfinished to talk about the Gondola meme and explaining Japanese slang), and has talked about her ADHD condition.

The mood during her streams can be heartwarming on rare occasions. Although there are instances where messages left by chatters rubbed her the wrong way despite their supportive intent, there are also instances where she voiced her appreciation for the feedback and support she received, such as her birthday stream. During her "MBTI Zatsudan", she gave encouraging advice to an anonymous submitter who voiced his worries about his Japanese skills.

Profile and Events
Beatani is a 26 year-old polar bear that used to be an average office worker, until her sister, Chihiro, threw her into the internet on October 2019 as a result of a fight and trapped her in there. She mentions circumstances similar to those of the game Myst. After that, she started living on the "XP hills" (for reasons she herself doesn't know), a term she uses to refer to the hills that appear in the default Windows XP background picture, Bliss.

One of Beatani's goals is to escape the internet after reconciling with her sister. Her other goals are to get 1000 friends, and have a talk with Hiroyuki of 2channel fame.

This is a transcript from her introduction video, 「姉が小石と小石チョコの食べ比べをしています」:

“Hello! I am Kumagai Chisato. I was supposed to be an ordinary office worker... but I had a fight with my sister, who possessed unusual technology, and because of that I was trapped in the internet. I was locked in an alternate dimension because of this fight with my sister. It's a situation similar to that famous mystery-solving game Myst! Since then, I've been drifting along the seas of the internet... and it's been really lonely!! Ahh, this is a painful part of my virtual existence. Because of that, for the sake of making friends, I've decided to become a VTuber! If it's possible, I want to play with (you), the viewer! If it's okay to be friends... because my surname is Kumagai, please call me Beatani!”



Background
Both her YouTube and Twitter accounts were created on January 2021. Her YouTube channel shows activity as early as 10/02/2021, and a proper self-introduction stream was broadcast on 27/02/2021.

March 6th, 2021 marks the date when Beatani expanded her following by advertising overseas, and a debut for English-speaking audiences (a summarized version of her self-introduction from the previous month) was released. As explained in a posterior zatsudan, although she planned to do English videos, she didn't originally plan to do the streams themselves in English.

Membership
Beatani announced on 29/03/2021 that she could open her YouTube membership, and enabled membership at the same time as her celebration stream "[祝！monetization]OPEN MEMBERSHIP & SING A LITTLE". She was surprised, as she did not expect more than 10 people to become members, and much more people than that joined.

End of activities
On Nov 10th 2022, during the stream "ばよえ～ん" and in a community post, she announced that, because she achieved her goals, she would stop making contents for the "[Beatani] project" after her last stream. She would stream her last public stream, "what can I do!??!!??!", on Nov 14th 2022.

Fan Name
When Beatani was asked how to call her fans, she had to think of a name, and proposed calling her fans Friends, BeaTomo, BeaFriends, or Sentries. Beatani ran a twitter poll between the last 3 names and Sentries won. The next day Beatani decided that she would call her fans Sentries. As Beatani's content shifted away from Slay the Spire and as she gained a large amount of new fans the usage of this name stopped. Eventually, Beatani said that she considers her fans to be family, and she mostly refers to them as dads; her "fan-family" also includes moms, brothers and sisters. Later on, Beatani posted art of "Listener-chan", a character that represents her fanbase.
