May Nakabayashi (born October 21, 1989), better known by her stage name, May'n, is a young, amazingly talented Real Life Idol Singer from Japan. She participated in the 28th "Horipro - Talent Scout Caravan - Love Music - Audition", where she survived the final elimination round to become one of the top 4 out of 34,911 hopeful singers. At Age 13. Her popularity exploded when she was made the singing voice of Sheryl Nome, performing numerous J-Pop numbers written by Yoko Kanno. Despite a blossoming career, Sheryl Nome still sells more albums than she does, mostly because of YOKO KANNO, though she did help May'n with one of her own songs.
In person, she is rumored to be very Moe, and she once sang a duet of Totsugeki Love Heart with NEKKI BASA-err, Yoshiki Fukuyama, an event which nearly destroyed the world with awesome (And you, too, can be witness to The Power of Rock thanks to YouTube!). Aside from her work as Sheryl Nome, she's also well-known for her work on the theme song to Shangri-La and a few other anime courtesy of May'n.
Has a movie coming out that is basically: MAY'N: THE MOVIE - IN 3D. The trailer consists solely of May'n sitting in a plain white room with speech notes and a blatantly plain outfit telling the audience about the movie.  It is apparently a documentary and live concert, in 3D, of course.
- Accel World - Theme song: Chasin' the World.
- Azur Lane - Theme Song: Graphite/Diamond.
- Aria the Scarlet Ammo - Theme song: Scarlet Ballet.
- Love Get Chu - Theme song.
- Macross Frontier - Singing Voice of Sheryl Nome (21 songs (roughly) and almost assuredly going to be the final count. The first of two movies gave her Eight new full-length songs. The second, alas, favored Ranka more, thus Sheryl only got one new full-length song, another version of Diamond Crevasse, and really the title song to the second movie. Seriously, when you write the lyrics to the song in your own blood like Sheryl did, you kinda own it.)
- Shangri-La - Theme song.
- Ōkami-san - Theme song.
- Kamen Rider Fourze - Ending songs "Giant Step" and "Cosmic Mind" (along with Yoshiharu Shiina of Surface; the pair form a special group called Astronauts.) She also released a solo version on her newest album HEAT.
- M3: The Dark Metal - Theme Song: Re:Remember, and Image Song: Darega Tameni
Not the biggest body of work, but Sheryl Nome is her own body of work. She also has a few solo albums as May'n, and a cluster of singles. Since becoming Sheryl Nome, she seems to release one Sheryl Nome cover per album, the first being a pretty straightforward version of Lion, where she sings both Sheryl's and Ranka's parts, and the second a much different version of Welcome To My FanClub's Night (May'n On Stage!). She also apparently has an acoustic version of Diamond Crevasse bouncing around (a song which Sheryl Nome herself has three versions of. It itself is really second only to Do You Remember Love? and has made a compelling case for becoming a franchise staple song like Do You Remember Love? and My Boyfriend Is A Pilot). Doubt of her singing abilities will be met with extreme musical prejudice.
May'n provides examples of the following tropes:
- Anime Theme Song: Plenty, see above.
- Child Prodigy: Began her professional career at 13 years of age.
- Gratuitous English: Occasionally...
- Idol Singer: Currently one of the most popular and prolific ones in the active scene
- Older Than They Look: She's in her early 30s, though she appears to be a girl in her teenage years.
