Iron Tager (テイガー), also known as TR-0009 Tager or the Red Devil (赤鬼), is an agent of Sector Seven, infamous for his color and stature. Despite his appearance, Tager is much more gentle and intelligent than one would initially believe, and he is infinitely loyal to Kokonoe. In his life before becoming the Red Devil, Tager was the captain of Bullet's Mercenary Squad.
Tager debuted as one of the original twelve playable characters in BlazBlue: Calamity Trigger.
