Manipulation

Manipulation (操作系, Sōsakei) is one of the six categories of Nen aura types.

Description
If a student moves the leaf floating on the water in the glass during their water divination, they are a Manipulator (操作系, Sōsakei). Abilities belonging to Manipulators allow the user to control living or non-living things in a certain way, the main advantage being able to 'manipulate' enemies. The degree of control is principally determined by a condition that usually puts the manipulator at risk (attaching objects on the enemy, touching the enemy in a certain way) and of course the larger the risk, the better the degree of control.
