Oboro Gesso-Shiki Tohjutsu (朧月相式刀術;Oboro Moon Phase Style Fencing) is the secret style used by the head household of the Oboro family.

About
Oboro Gesso-Shiki is a form of swordsmanship passed down through the Oboro's founding bloodline. In contrast to the traditional swordsmanship of the Oboro School, this style has been passed down through the ages to the Oboro household's heir. Gesso Shiki is a fighting form designed to take down hordes of adversaries single-handedly, created by the Rising Moon Clan of assassins developed by the first Oboro ninja. Rooted in the concept of ichi no tachi, or to strike in a single blow, practitioners of this style use a combination of immense speed and agility, battōjutsu, and acquired, observation-based pseudo-clairvoyance that permits a practitioner to anticipate an opponent's movements. Both offensive and defensive maneuvers are executed with minimal movement to increase a practitioner's ability to counter-attack and to conserve energy. As such, made with efficiency and sparseness of exertion in the face of warfare scale battles yet with powerful and coordinated movements to easily fell threats in long and undetermined periods of time, it is among one of the strongest and oldest shinobi-kenjutsu styles in Japan.

However, Jo Musashi of the Musashi family, succeeded in developing his own unique version of the style, adapting the basics of the style to evolve the Ninja Arts of the Oboro School even further.
