Reol (れをる) is an utaite who has a high pitched, yet strong voice that is sometimes described as shota. She frequently autotunes her voice so that it fits electronic songs well, while it gives songs of other genres an interesting touch. She once sang in a soft voice, as seen in "No title." Her vocals were similar to that of Nanahira.
She is also able to sing in a low voice, clearly seen on her covers of "Jabberwocky・Jabberwocka" and "Jitter Doll". Her lower vocals seem to have somewhat of a nasal quality to them.
She is capable of singing scream vocals, but has only ever done so for her cover of Abnormalize.
Her first cover was "Yurufuwa Jukai Girl" in June of 2012, which was remarkably popular, and has over 168K views as of May 2015. Her most popular work is "+♂", which has over 6 million views as of January 2017. It was also a collaboration song with GigaP in which she wrote the lyrics. She uploaded her cover at the same time as GigaP uploaded the Kagamine Len version. They had been frequent collaborators on many songs before that and still continue to work together, as not only songwriter and lyricist, but also as singer and mixer.
She often collaborates with kradness as their voices complement each other very well. Also, their relationship seems to be quite close as seen on their conversations on Twitter.
She uses a Shure BETA 58A microphone for lives, and a BETA 87A for recording and aside from that a IF:UA-55. She also uses a Roland UA-55 audio interface, Cubase and FL Studio software, and an Audio Technica M-50 pair of headphones.
Her favorite food is beef while her favorite drink is the Green Tea Frappuccino at Starbucks.
