Jk Genkai Koubi Goui Sounyuu De Bachibachi Niku 2021 -

I should also make sure that the terms are translated appropriately. "Genkai" here might not be debut if they disbanded, so maybe it's a pun or a reference to their comeback. "Niku" meaning muscle could relate to physical performance or training. Alternatively, "niku" can also be slang for something else, but in this context, probably physical aspects. The term "goui sounyuu" might mean combining different elements to enter the market, possibly in a business or media sense.
