For context, I downloaded this off Nicovideo, a Japanese video sharing site. The poster only called her a blonde "junior idol" which is inaccurate because junior idols don't really exist out of Japan. That video has since been deleted off the platform. At the time, "oneesantess" was an account dedicated to gooning to teens. He had a Telegram account, but I couldn't contact him. I asked around on 4chan, but got no leads, they just lied and said her name was oneesantess.
