ABOUT US
4 GIRL∗ERA (often abbreviated as 4Girls or ERA) is a diverse girl group that debuted on November 3rd, 2025, through an online chat tool called "Discord". The group consists of 4 members – Eve, Ray, Reika, and Aya.
NAME
The group name was formed through the first initials of their first names in order of oldest to youngest (E R/R A), and the fact that they are all femininely aligned.
MEMBERS
Eve is the MV creator in ERA and the oldest. She is a very quiet and peaceful soul, often described as sunao cool by the people close to her. Sometimes thought of as a robot girl due to her high ego, but she actually has the mentality of a kitten in a wet box. Only her friends know her true colors. She usually works closest with Reika.
Ray is the composer in ERA. She cares deeply for everyone and everything but tends to mask it, thus making her known as the tsundere. She is considered the most levelheaded one of the group due to her self-sacrifical tendencies. She is the newest member of ERA, and tends to work well with everyone in the group.
Reika (also known as Riri) is the artist in ERA. She is a very social girl, and is regarded as a bit of a bimbo, as well as an erodere. However, looks are deceiving, and she is very perceptive to things happening within the group. She generally gets along with everyone, though she is frequently seen assisting Eve.
Aya is the lyricist in ERA and the youngest. She is a little naive, but means no harm – some would see her as the heart of the group in a way. She is sometimes seen playfully bickering with Reika, but loves all of her friends equally and is extremely grateful to them for accepting her the way she is. She can be a bit of a megadere at times, so she works well with everyone.
