Kenbunshoku: Kaitai Shuri

Kenbunshoku: Kaitai Shuri (見聞色 解体修理, Kenbun-shoku: Kaitai Shūri; lit. "Color of Observation: Repair by Disassembly") is a technique developed and used by Quill Pencilio with assistance from his mentors, as a means to capitalize on his unique insight on the world as an artist, through the lens of Haki. Kaitai Shuri is a technique that enables Pencilio to slowly understand the inner workings of anything through observation, and subsequently highlight the weaknesses of said structure.

Kaitai Shuri is an unorthodox Kenbunshoku Haki technique in that it lies within two categories of the Haki Development System. While going through the process of observation, Kaitai Shuri is classified as a 5th Dan technique. When weaknesses are pin-pointed, Haki internalization is at a degree that it becomes a 6th Dan technique.

Pencilio himself utilizes the technique in order to improve on his own errors, and by Kurama's admission, is the reason why his growth rate as a combatant is accelerated when compared to his peers.
