[4][5] Their songs incorporate elements of metalcore, hardcore punk, and nu metal, with a blend of hip hop and electronica.

[6] The band was formed by four high school friends due to their shared admiration of Maximum the Hormone, as a part of their light music club activities.

[11] Their music has been featured in the DMM TV drama Kenshiro ni Yoroshiku and the Japanese variety show Kannai Devil.

[7][14] They introduced the band to Hettsu who was initially surprised that "cute and clear" Yukina listened to such "indecent songs".

[15] During their first year of high school Yukina decided to form a Maximum the Hormone cover band with her friends after watching an upperclassman perform.

[8] They released their third song, "Envy," in June 2017, which was sold exclusively at their live performances as a part of the "Crash Over" demo CD.

"[18] On October 17, the band announced the release of their debut mini album, Cherry Blossoms Are Blooming, along with an accompanying tour.

[21] Boa decided to depart from the band in September 2018, leading them to continue their live performances with the assistance of various support drummers.

[8] In November, they embarked on the "Flowering Declaration" release tour, which included shows in Shinjuku, Nagano, Osaka, Nagoya, Shizuoka, Kyoto, and Tachikawa.

[8] In August 2020, they released "Sentimental Heroine" on different music streaming platforms, accompanied by a lyric video on YouTube.

[23] Backers were offered various rewards, with the highest tier receiving a new customized song written by the band based on their requests.

[24] The success of the song led to more opportunities to perform at different musical events and increased attendance at their shows.

[8] Due to the band members still being university students, they had to balance their studies, part-time jobs, and recording sessions while continuing to perform at live houses.

[8] In April 2022, they unveiled the single "Love♡ Ranbu", followed by "Neet Game" in August 2022, the latter of which also received a music video.

After successfully establishing themselves in the indie scene of Tokyo, by 2022 they were performing at various venues in Shimokitazawa, Shibuya, Nagoya, and Shinjuku.

The success of the song attracted the attention of international promoters, with the band receiving invitations to perform at festivals in several countries including MetalDays,[26] Leyendas del Rock,[27] Dynamo Metalfest,[28] Blue Ridge Rock Festival,[29] Louder than Life,[30] and Aftershock.

[32] Following a period of absence from live performances, it was announced in April that Sae would be departing from the band for personal reasons.

[34] However, they ultimately opted to search for a permanent drummer to ensure a complete lineup for their major label debut.

[41] It received positive critical reviews and peaked at number 26 on Billboard Japan's weekly album charts.

[42] In the following month they accompanied the British metalcore band While She Sleeps on their Asia tour, as an opening act.

[46] The band's second European and North American tours were announced in February with Left to Suffer and Outline in Color as supporting acts.

[48] In June the band announced their North American tour as an opening act for Jinjer, along with Born of Osiris.

[52][53][54] Music critic Katarina McGinn opines that the band "incorporates as many different outside influences from a variety of genres along with the metalcore backbone to make a slurry that feels as inventive as it does abrasive".

[56][57] Their tongue-in-cheek lyricism and genre defying compositions share an aesthetic with Maximum the Hormone, whom they used to cover in their early days.

[17] Yukina cites Maximum the Hormone, A Crowd of Rebellion, Hysteric Panic, and Ellegarden as her influences.

[61] Contemporary Japanese culture and fashion centered around the Akihabara and Harajuku districts of Tokyo are a notable part of the band's image.
