Nobody knows the history of "Red Wolf", but everybody knows his capabilities.
On his first day in the Alliance Army, he displayed tremendous combat capabilities by taking out a rogue combat machine on his own. It is because of this that he was assigned to the elite force of the Alliance Army, the Sacred Vanguards. During his service in the Vanguard, he has shown acute logical thinking to accurately predict Night Blade's plans and twart them.
Now that he has been made leader of the vanguards, will the vanguards be able to create a miracle? We shall see!
