Message from HIKAKIN & SEIKIN:
"We are really happy to be able to sing 'We Are!' from the nationally popular anime 'ONE PIECE,' which everyone knows. We are so moved that we want to tell ourselves in our elementary school days, who used to look forward to watching the anime every week, 'We are singing this song in the future.' At that time, We were watching it in front of the TV only thinking, 'It's a good song.' And we are impressed and honored that we are having this unexpected experience, so we want to sing it with all of our heart."
