In September 2015, Shosetsu Minegishi (Ba) formed the band "Oisicle Melonpan" after recruiting his college classmate Nakashima (Vo & Gt) and high school classmate Shuntaro Hara (Dr).

On October 1, 2025, they released their major-label debut and 10th mini-album, bouquet.
The band followed the release with their largest tour to date, covering five Zepp venues nationwide.
The tour concluded in great success, with sold-out shows across various locations, including the tour finale at LINE CUBE SHIBUYA (Shibuya Public Hall).

During the final performance of the tour, they announced that their new single, "Tsutsuji no Kareru Koro ni" (azaleas), will be available for digital release on April 15.

They continue to live their daily lives in good health and spirits.
