Valshe (バルシェ) is an utaite well-known for her lower range and distinctive husky voice. She's well known to be a "ryouseirui", people who are able to sing both genders.
She and producer-utaite Tourai have collaborated on many projects. She is also known to be good friends with the illustrator Hakuseki, who also does almost all of the artwork for Valshe's albums and videos.
Valshe is most commonly associated with Kagamine Len by their looks: blonde hair and blue eyes, but without the frontal sweep bangs or ponytail in the back.
