Aen is not huge, or intimidating; hell, he doesn’t even look particularly… Well, dead.
People shouldn’t fear him because he’s a hulking mass of muscles.
They should fear him because he fights with all the anger, tenacity and joy of someone who could never fight back, who bottled up their anger for their entire life…
…Only to wake up one day and find out they were given all the fury and power of a howling snow storm.
