Drinker Abilities

Nails
Roger's nails are the same as other Drinkers, they're incredibly sharp and allow him to do loads of damage.

Symbol Instant Kill
When Roger activates his symbol he gains access to an attack where he uses his nails to completely eviscerate an opponent, cutting them into cubes before eventually killing them. This is a death sentence to most people hit by this move, with the exception of Min Aji, who only survived because she wasn't the intended target. This attack has been used to kill the likes of Min Sagi, Salem, and Ciel.

The King
Roger serves as the King's second in command, however, it is revealed that Roger despises the King, and is always plotting a way to usurp him and take the throne as King of the Drinkers. Despite hating him, Roger still holds respect for the King's abilities and strength.

Min Aji
When Roger found that Aji was the daughter of the King, he was excited. He saw her as a way to kill the King without himself getting involved. Finding that it would be easier to keep her alive and have her do the work for him. To do this, Roger needed Aji to have her symbol awakened, in order to do this, he murdered Min Sagi, sending Aji into a rage and transforming into her monster form, where Roger was able to do minimum damage. Once Aji activated her symbol, Roger couldn't compete with her strength. After being captured, he trusts that she will be able to kill the King.
