After speaking with Reflejo, one of the trustworthy Regulars he had sent to keep watch on Jyu Viole Grace, Poken gave Reflejo permission to kill all of Viole's teammates as Viole had broken the rules first.
After Ha Jinsung left Karaka's hideout, Poken appeared and told Karaka that the Submerged Fish had replied. Realising that Viole would soon become a D-Rank Regular and considering the existence of the Hell Express, Karaka instructed Poken to make sure not to make any more mistakes.
Powers and Abilities
It is unknown how powerful Poken is, although his status as a FUG executive and Karaka's most seen subordinate could mean he is relatively powerful. However, it is known that he is able to grant people a part of his 'shadow'. People that possess part of his shadow are able to augment their powers many times over at the cost of destroying their body.
