Reverse-Flow Control

""There is only one thing needed to defeat an enemy using reverse-flow control; which you just have to be overwhelmingly more powerful than your opponent.""

- Lightpen, Vice-President of the Research Association

Reverse-Flow Control (역흐름제어, yeokheureumjae'eo) is a Shinsu Manipulation skill that is mostly used to "stop" the movement of various things, from Human, Shinheuh, inanimate objects (such as remote control device) or even the "Shinsu" itself. This skill can "temporarily" immobilize person, object or "freezing" the Shinsu like Frozen Ice. It can be used at close range or even long range. However, Reverse-Flow Control can be resisted and overcome if the target has very high Shinsu Resistance or powerful Shinsu control that exceeds the power of the user.

About
Reverse-Flow Control is slower than normal "Flow Control", and thus generally means the user can only control a smaller amount of Shinsu in comparison to flow control, but allows the user to completely dictate the "flow of Shinsu", allowing them efficiency for the amount of Shinsu used. Reverse-flow control is mostly used to "destroy" or to "stop" the enemy.

Reverse-flow control requires more caution when compared to flow control. In fact, to use reverse-flow control, you need to be able to read the flow of Shinsu more accurately than you need to for flow control. You instead break, block and shatter the flow and make it your own. Changing the flow of Shinsu in the wrong ways can be unintentionally destructive, requiring caution. Even though this may sound very destructive, flow control is actually better for destroying things.

Lighthouse
Lighthouse is one of many item that can use Reverse-Flow Control. This is known as the Lighthouse Flow Control.

Notes and Trivia

 * With enough skill and power, one can freeze not only people's movement, but also inanimate objects and even Shinsu.
 * This is apparently a rare technique, especially on the lower Floors of the Tower, and may be a difficult one to learn as Quant notes that it took him decades to learn it.
