2017-2018: Formation
On May 5, 2017, Hello Pro Kenshuusei held their annual test event where representative director  suddenly decided that several members including Ichioka Reina, Takase Kurumi, and Kiyono Momohime would debut from the trainee program, with the latter two forming a "new section" that was focused on theater but different from Engeki Joshibu. On June 26, 2017, through a special episode of Hello! Project Station, it was then revealed that Ichioka would debut as the leader of a new group, and that additional members would be found in the future.

On March 30, 2018, an update on the group was posted to the official Hello! Project website, announcing that the group featuring Ichioka would be a "performance group" that aims to elevate singing and dancing through physical expression, while the new section including Takase and Kiyono would become a second new group with the image of a "small theater troupe" that uses expressive power and theatrical elements in their singing and dancing, and both groups would begin activities sometime in the summer or fall. On the same day, it was announced that an audition to find members for the new groups was slated to begin in late April. Following a postponement, the Hello! Project "ONLY YOU" Audition finally began on May 11.

On June 9, 2018, during the Hello! Project Kenshuusei Happyoukai 2018 6gatsu ~Niji~ at Zepp Tokyo, it was announced that Shimakura Rika, Nishida Shiori, and Eguchi Saya would join the performance group and Maeda Kokoro, Yamazaki Yuhane, and Okamura Minami would join the theater group, with the possibility of more members being added to both groups following the conclusion of the ongoing audition. Two days later, it was announced that both groups would make their stage debut in the Hello! Project 20th Anniversary!! Hello! Project 2018 SUMMER concert tour beginning on July 14.

On July 14, 2018, all of the members' profiles were removed from the Hello Pro Kenshuusei page on the official Hello! Project site, indicating they are no longer trainees.

On October 19, 2018, the groups' names were revealed as CHICA#TETSU and Ame no Mori Kawa Umi. Together they would form a collective group named BEYOOOOONDS, and instead of the Hello! Project "ONLY YOU" Audition winners joining either of the two groups, they would become part of BEYOOOOONDS.

On December 3, 2018, during the BEYOOOOONDS Ouen Kikaku FC Event 2018 ~Fuyu no Jin ZIN~ at Yamano Hall, the winners of the Hello! Project "ONLY YOU" Audition were revealed as Satoyoshi Utano, Kobayashi Honoka, and Hirai Miyo and the members were given their image colors. BEYOOOOONDS would begin activities as 12 members in the Hello! Project 20th Anniversary!! Hello! Project 2019 WINTER concert tour.

2019
On February 5, six members (Ichioka Reina, Shimakura Rika, Takase Kurumi, Maeda Kokoro, Hirai Miyo, and Satoyoshi Utano) appeared as back-up dancers for Suzuki Airi during her cover performance of Rats & Stars' "Megumi no Hito" on Utacon.

Group Name Origins
The name was chosen with hopes of the group growing freely towards the future, beyond their existing framework, with the group aiming for an ever-changing appearance similar to slime.
 * BEYOOOOONDS

Chica is Spanish for "girl" and tetsu (哲) means "philosophy". The two words were brought together to create a group name that means "girls who think deeply of things".
 * CHICA#TETSU

The name represents sources of life such as nature, and each of the founding group members has a part of their name with a meaning related to nature: kurumi (くるみ) meaning "walnut" from Takase Kurumi, ta (田) meaning "rice field" from Maeda Kokoro, hane (羽) meaning "feather" from Yamazaki Yuhane, oka (岡) meaning "hill" and nami (波) meaning "wave" from Okamura Minami, and momo (桃) meaning "peach" from Kiyono Momohime.
