Takafumi Adachi (足立 たかふみ) is the Japanese creator of the Metal Saga, consisting of Metal Fight Beyblade (Beyblade: Metal Fusion), Metal Fight Beyblade Explosion (Beyblade: Metal Masters), Ballet Hero Fantasy Dan's adventure feat. Steven McRae, and Metal Fight Beyblade 4D (Beyblade: Metal Fury), He also writes and illustrates the manga of the Metal Saga. Adachi has ties in Duel Masters, another franchise created by Tomy, in which Adachi created a manga unrelated to the main storyline of it. Also, while Metal Fight Beyblade was under development back in 2008, Adachi was asked by Tomy and quote, "Make a new Beyblade series unrelated to the first one." With this, Adachi quickly revived Beyblade and had it become even more popular than the original.
