The Sinful Iron wasn't always as ruthless as the current version of him.
Being the leader of the biggest terroristic association in the whole of Ouroboros had definitely helped… but it wasn't all there was to his identity.
Neither black nor white, in the village where he was born, he took his current name, from the color of the mineral, as if to represent his sadly disappointing skills.
Where he was born, after all, you either could make yourself a name through smithing or distilling spirits… sadly Iron didn't excel in those specific disciplines.
His case differed from Eve's or Cain's.
No discrimination or coercion took place, but his soul still felt pain each time he saw a smile in an accomplished individual.
*Why am I not like them… What's wrong with me?! *
For long years his self-afflicted torture continued and his grudge kept building up, like the pressure of vapor inside a pot.
