Leuvis

Lewis (ルイス) was one of the antagonists of The Promised Neverland. He belonged to the group of Demons called the Poachers. It was later revealed that he served as a purveyor for the Grand Valley orphanage that delivers the children to Goldy Pond.

History
When Lewis witnessed Emma's potential in killing his comrade, he mentioned how he had not felt such a thrill and been so entertained since he faced another group of children, refering to the unnamed man and his friends.undefined

Appearance
Lewis was a tall and slender demon with three fingers on each hand, and three toes on each foot. His entire body was clothed in black with a high collared cape draped over his shoulders. He also wore a matching top hat decorated with rope-like looms. Like most demons, his face was covered with a mask with four holes on top of each other with the upper three allowing him to see. When he grinned, the bottom hole in his mask revealed his sharp canines. The full extent of the features that lie under his mask were revealed when  the man  successfully shot and broke his mask. undefined

Archduke Lewis owned a pet called Parvusundefined which was often seen on his shoulder. The creature has two eyes - one on top and a much bigger one below - and the physical features of a monkey. A tiny crown is perched on top of its head.

Personality
Not much is known about Lewis' personality currently. But he appeared to be a rather laid back individual who sees the other poachers' intention of playing with their prey (the human orphans) as immature.undefined

Search For Minerva Arc
Archduke Lewis' regenerative abilities were affected by his age, which was revealed when he was blinded by the flash of light, and when his hand was blown off and he suffered a broken arm and did not quickly recover. Despite these handicaps, he was still able to stab Emma.

After engaging in a fight with Emma, Shelter B06-32 Unnamed Man, Ray, Adam, Violet and Nigel, he met his end after being shot and killed by the unnamed man.

Enhanced Reflexes and Speed
Lewis was proven to have had a high degree of speed and agility. This was shown when he was able to catch the axe that Emma threw at a high velocity before it stabbed his comrade's eye in a nick of time. Lewis possessed inhuman resilience, most commonly seen from being unaffected by momentum build-up. He can take attacks and exertion, even survive impacts that would easily kill normal humans or several of his kind. This was proven when Emma ambushed Lewis by firing dozens of bullets at him at different angles, but failed to cause damage as not a single bullet impaled Lewis as he managed to dodge and catch them.undefined

This shows how Lewis' speed extends to his reaction time and reflexes; he is able to think and perceive at superhuman speed, he is able to determine angles, distance, speed and trajectory of objects with extreme accuracy.

Enhanced Hearing
He immediately located and attacked him just from the sound of his voice. He was able to make up for his lack of vision with his sense of hearing.undefinedWhen the man managed to shoot and crack open Lewis' mask, leaving Lewis in a moment of disarray with his sense of sight. Lewis still managed to attack as he swiftly sliced Pepe's left shoulder and disabled his arm using his sense of hearing.

Hunting
He was skilled at hunting Glory Bell escapees. The members of the Goldy Pond Resistance are careful of him.undefined
