In 2014, Aoi Chihiro joined Tsuyogari Sensation as a founding member. She was part of the group for the latter half of the year, and graduated on Februrary 15th, 2015 without releasing any material.

Around the same time as her graduation, Chihiro auditioned for BiSH, eventually being announced as a founding member and captain of the group the following month. She changed her stage name to Cent Chihiro Chittiii and her first album, Brand-new idol SHiT, was released in May.

In April 2016, Chitti collaborated with GHOST ORACLE DRIVE to provide a song, "Human After All" for the anime GOD EATER. The song was used as the ending theme for the 6th episode. Shortly after, Chittiii was demoted from Captain to "Bag Lady" after failing a DiET or DiE challenge.

When Ayuni D joined in August, she took Chittiii's original "Little Sister" member role and Chittiis new role was changed to "Looks serious, vain, has up to two boyfriends", a reference to the song "SCHOOL GIRLS, BANG BANG, which she wrote the lyrics to.

Chittiii joined the "Idol Supergroup" NATASHA, in September 2016.
