Sean Datz

Sean Datz (ショーン・ダッツ) was a member of Under. He was a Negator with the alias Unseen.

Appearance
Sean was a young adult in his late teens to early twenties. He had three eyes, with the third one situated in the middle of his temple, and light-colored hair with long sideburns that frame his face. He kept his hair parted in the middle to allow his third eye to see. He also had two piercings in his right ear. During his mission with Rip, he wore a backwards cap, a dark-colored down jacket and a pair of denim jeans.

Personality
Little of Sean's personality is known. When first shown, he was shown using his power to steal an apple from a fruit stand, implying that he has little issue with abusing his power.

History
Sean was part of a Brazilian gang and abused his power. He used it for robbery and murder.

Spoil Arc
His capture was part of the 99th Penalty quest, but he was instead kidnapped by Under during a crime spree before the Union could find him.

Autumn Arc
Sean accompanies Rip in his mission to stop Andy and Fuuko in their quest to subdue Autumn which lead to Sean and Rip following Andy, Fuuko and Anno Un to the writer's house. With Andy and Fuuko incapacitated as they journey through Andy's memories, Rip fights Anno Un to get to the two Union members and Sean uses his Negator abilities to stay hidden.

After severing Anno Un's remaining arm, Rip warns Sean to refrain from hurting Fuuko. Sean, however, ignores Rip and quickly approaches Fuuko with his switchblade on hand, aiming to slash open her throat. As Sean closes in on Fuuko, Andy suddenly appears and Anno Un promptly instructs him to use his Deadline attack. Andy follows Anno Un's command without hesitation and uses his blood to slice the area around him. Sean is caught in the attack and is cut in half. As his upperbody falls to the ground, Sean's death deactivates his ability and the group is surprised to see the dead Negator.
