Taka (ONE OK ROCK) and Shimizu Shota have launched a new project called [re:]. Under this project, they have revealed a new song titled "Mou Ichido" featuring artists from the same generation. 

Taka and Shimizu launched [re:] as they wanted to do something with artists from their generation during these difficult times. As such, they gathered Abe Mao, Ayaka, Aimer, KENTA (WANIMA), Nissy, and Miura Daichi, artists who were all in support of their idea, and created "Mou Ichido" to relay the message "let's hold hands once again and walk towards the future."
