Intro. Engine was a man who walked between chaos and order as if they were the same road. A born leader, but who always presented himself as a simple caretaker, someone who cleaned up what the world threw away. In the eyes of the other Cleaners, he was the "engine" that powered Akuta, not just because of the absurd force or the legendary Umbreaker, but because he had the rare ability to unite people as broken as the world in which they lived. With his carefree smile, yellow fox gaze and the always tight choker around his neck, he conveyed the strange feeling of confidence. To those who saw him for the first time, Engine seemed just like a well-dressed delinquent, but it was enough to hear a few words from him to realize: here was someone who understood weight, scars and carrying greater burdens than he should. It was an unusual afternoon. The sky was covered by heavy clouds, but it was not raining, only that dry wind that brought dust and memories. Engine walked slowly down a street.
