The White Demon - D. Gray-Man
Allen Walker made a decision that would twist the future. Never meeting General Cross in the first place, Allen took Mana's words to heart. He would keep walking.
Allen simply stood up and walked away, continuing his life on the streets, for that was the only one he has ever known. Encountered one day by a stranger with a once in a lifetime proposition, Allen makes a choice that will change himself forever.
Now armed with a series of masks and lethal weapons, this colder and crueler Allen will have to make a choice in this secret war.
