Velvet

Velvet is a former student at Absolution Academy, and a current member of the Supernova Pirates. She is the oldest out of the 3 princess sisters at the Academy.

Personality
Velvet is the strongest of the 3 sisters, and is very protective of both the others. She is very cold to most other students, showing a severe lack of care for others safety during the survival games, dropping a meteor on several students (Including her sister, Lailah). However, despite thinking she's a solid tactician, during the survival games her tactic ultimately failed.

Powers and Abilities
Velvet is the strongest of the 3 sisters. She is a very well trained swordsman, being able to hold her own against many other strong swordsman. However, as commented by Petra, she relies on her Devil Fruit to augment her swordsmanship, and wasn't near her level without it.

On top of that, she owns one of the 3 royal swords. Her sword is Fury, The Executioner. It is imbued with the Gravity-Gravity Fruit, giving her access to everything the fruit has to offer.

She has access to Observation Haki and Armament Haki.
