Knov

Knov (ノヴ, Novu) is a smartly attired hunter dressed in glasses and a suit. He is Palm's master and the target of her affections. Knov can create warp gates to a "safe house" dimension, which he creates doors in. It is similar to teleportation, but instead of instantly arriving at the destination he goes to his "safe house." His safe house is basically a windowless room, with multiple doors around the room. Within the safe house, he can store items and/or people. When infiltrating the Chimera Ant King's palace in order to place a portal, he came into contact with Shaiapouf's En. It frightened him so much he suffered a nervous breakdown and retreated from the battle.

Combat
Knov is a conjurer with a teleportation ability called Hide and Seek. By touching a flat surface, like a wall or the ground, Knov can set and open a portal leading to an artificial Nen dimension—a four level mansion containing twenty-one rooms of various sizes. Each portal is linked to a specific room, with the maximum number of entrances being dependent on the size of the room, with each room being completely separate from the other rooms. Normally each entrance can only lead back to the portal Knov created for it, however, Knov can use a master key to connect any room exit to any previously set portal. When not in active use by Knov, the portals are closed and impossible to detect.[24] Knov has also been seen using his teleportation ability offensively. "Scream" allows him to open a portal in midair and wrap it around his opponent. When the portal closes, whatever is caught within is removed from the body.
