Mark Grove began training in martial arts in 1972 and he has been devout to pursuing the art of the Ninja every since. During those early years he was exposed to many exotic arts that few had been exposed to in the United States, including sword fencing (kenjutsu) staff fighting (bojutsu) throwing blades (shurikenjutsu), short bow and arrow (hankyujutsu), and grappling (jujutsu).
In the late 70's Mr. Grove meets Shihan Frank J. Goody, a Master of multiple martial arts, including Nagai Ryu Jujutsu, Matsuyama Ryu Yawara, and Kota Ryu Ninjutsu. Shihan Goody offers high praise of Mr. Grove at a Martial Arts demonstration.
Always drawn to classical Ryukyu kobudo, Mr. Grove learned a variety of Okinawan weapons, but he was especially drawn to the staff, flail, and iron truncheon.
Mr. Grove and Shihan Goody reunite in 1981 and Mark receives vast amounts of information about Kota Ryu Ninjutsu including 16 unarmed techniques with four variants each, scrolls related to the art of mysticism called Gorin Kuji Myo Himitsu Shaku, and in-depth information about the art of joint manipulation and striking using a short handheld stick.
In 1983 a professional photographer saw Mr. Grove perform in a demonstration. She asked if he would allow her to take one shot because she believed she could capture his spirit with the sword. This image was the result.
In 1983 Mr. Grove is introduced to Hakkoryu Jujutsu practitioner Dennis G. Palumbo and is asked to teach classes in Ninjutsu at the Hakkosen Dojo in Aurora, Colorado. In 1984 Dai Shihan Palumbo officially recognizes Mr. Groves creation of the Kurai Kotori Ninjutsu system under the banner of the Hakkoryu Martial Arts Federation.
As founder of the Kurai Kotori Ryu, Mr. Grove assumes the title of Jonin (ninja leader) and focuses on the four core arts of the system, unarmed combat (taijutsu), acrobatic skills (karujutsu), the basic weapons of short staff, knife, chain and throwing blades (kihon nin-buki), and swordsmanship (kenjutsu).
In 1983 he begins chronicling the art in written form in what he calls the Arcanum of Ninja Tactics, an ongoing work that represents the evolving arts within the Kurai Kotori system.

In 1983 the Ninja boom is on. Due to the overwhelming popularity, classes grow quickly and new students are excited to train with classical Ninja weapons and learn powerful unarmed fighting techniques.
Although much of the training of the Kurai Kotori system takes place in the Dojo, but Mr. Grove is also dedicated to capturing the spirit of the Ninja by having his students practice skills within nature.
In 1986 Mr. Grove was asked to attend the 1st Annual Ninja Summit in Mentor, Ohio. The purpose of this event was to unite the different factions/clans of Ninja that existed throughout the world. Although the politics involved made it impossible for everyone to see eye to eye, it was still a powerful event that promoted the idea that no one had a monopoly on the art of the Ninja.
1986 also saw the birth of Kurai Kotori Ryu training camps, which would be held at various times over the years and be focused primarily on stealth, climbing, concealment, and group tactics.
Mr. Grove had the honor of studying with Small Circle Jujitsu founder Professor Wally Jay. Mr. Grove demonstrated all of the grappling skills within the Kurai Kotori system and the Professor assisted in refining the techniques using his small circle theories. As a result of this training, Mr. Grove made subtle changes to the system to implement this gift of knowledge from a true master.
In 1987 Mr. Grove was asked to become a member of the Samurai Society of America, an organization comprised of highly regarded and qualified instructors willing to share their knowledge and experience for the benefit of all martial artists. At this event Mr. Grove teaches short staff grappling techniques and elemental meditation.
In 1989 the Honshin Dojo is opened and there is a focus on creating historical Ninja gear in an effort to learn how it would have been employed in the past. Hanging in the upper corner of this photo is the "Mizu Gumo," or "Water Spider," used as a stealthy floatation device.

Mr. Grove seeks an outlet for his skills beyond teaching. His top students continue training as he embarks on a four year journey on which he learns all aspects of fight choreography and cinematic technique under professional stunt coordinators and fight choreographers. These new skills allow him to transition into the film industry as an actor and stuntman.

He opens a new training facility that teaches both martial arts and fight choreography, with a special focus on Chambara (classical sword slinging films) to pay homage to the epic Samurai and Ninja films depicting Japan's Feudal era.
March 21st 1995 Shihan Frank J. Goody passes away. Mr. Grove reflects on the many lessons from this great master, especially those pertaining to mysticism. To honor Shihan Goody, Mr. Grove devotes a great deal of time compiling and organizing all the written materials he received pertaining to the Ryobu Shinto doctrines that focused on the Ryubo Kuji (aka kuji in).
Mr. Grove travels to Canada to meet with stunt coordinator John Wardlow to discuss being the stunt double for John Lone in The Hunted. However, because of Canadian restrictions, Mr. Grove is not allowed to perform in that capacity. But he still provides Historical Consultation with his “Arcanum of Ninja Tactics” training manuals.
In January 1996 Mr. Grove completes an audio CD and training booklet called Ninja Chants of Power that contains a detailed account of Shihan Goody’s teachings. Mark shares this information with those interested in the mystical aspects of the Ninja lifestyle.
After receiving a copy of the Ninja Chants of Power CD, Koga Ninjutsu master Ronald Duncan contacts Mr. Grove and shares he was a long time acquaintance of Shihan Goody who respected his teachings and admired his experiences in the martial arts. O’Sensei Duncan suggests an exchange of information and they begin communicating regularly. The two become good friends.

Dai Shihan Dennis G. Palumbo passes away September 12th, 2014. Mr. Grove recalls something Dai Shihan shared with him when he was writing his first book on Hakkoryu Jujutsu in 1986. He said “We have a very short time on earth and if we are not careful, the wisdom we obtained during our lives will fade quickly after our passing, which is why I choose to share what I've learned through writing.”
Mr. Grove was there when the first box of books arrived at Dai Shihan Palumbo’s Dojo in 1987. Dai Shihan pulled the first book out of the box, took out a pen, and quickly scribbled something inside the book before handing it to Mr. Grove. “The first book is yours.” He said. Mr. Grove was honored and purchased a second copy so he could keep the signed one pristine.
Sara Salazar, after 12 years of being a Jiki Deshi, has proven her skills and is acknowledged by Mr. Grove as being the most accomplished and dedicated student he has ever trained.
