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.

Adachi specializes in the shonen-type of anime and manga.
