The three men wear animal-themed masks as part of their gimmick when on the job: Himekawa wears a rabbit mask, Kobayashi, a lion mask, and Masaoka, a bear mask.
Hired by Amachi Army Edit
Serving Under TFOA Edit
However, following a sound defeat at the hands of the Armament, the Demons' leader, Himekawa, decides to follow Murata Shougo into the Armament. He does not force the remaining two members to follow him, but Kobayashi and Masaoka do so anyway, as the three have been tight friends since childhood.
They served as the Armament's shadow force and flying column, often acting independently of the Armament's main body. However, they still receive their orders from the Head, Shougo, and follow them to the letter.
As the Armament's secondary force, the Demons mostly gather intelligence from the shadows and serve as intimidating, opening acts for the Armament's schemes.
