Anime watchers have most likely encountered the anisong writers FLOW or GRANRODEO at least once. They’re popular for making songs for anime such as Naruto (“GO!!!” or also commonly referred to “Fighting Dreamers”) and Kuroko no Basket (“Can Do” & “RIMFIRE“).
Recently they announced their collaboration song “7 -seven-” for the anime “Nanatsu no Taizai” (Seven Deadly Sins) as the ending theme song, and as of today the short version of the music video is available! The single will go on sale November 26.
Side note: Probably a coincident, but they’re exactly 7 members when combined, which perfectly matches the name of the anime.
