Sharp Mind

Introduction
Surudoi Chisei (鋭い知性 Keen Mind) is an invented form of Kenbunshoku Haki, merged with Rokushiki in its own.

Overview
This ability utilizes Kenbunshoku Haki, Life Return, and Kami-e. The practitioner needs to have a great control over his or her Kenbunshoku Haki to preform this unique ability. This ability allows the user to fully utilize his or her Kenbunshoku Haki, by fully controlling it and manifesting it as a circular room around the opponent. Some age greater than others however, being able to stretch the room further than others.

By utilizing Life Return and Kami-e, creates a general illusion of boosting their reaction time, Wheres once something enters the room, they can ultimately sense it whether it be a spider, or human, thus creating a secondary illusion of instantaneous speed.

Though other Kenbunshoku Haki users can stop this so called illusion, Surudoi Chisei practitioners usually have a better control over their Haki than others. This allowing the practitioner to completely surround themselves and opponents in Haki, allowing multiple unique abilities.
