ISHITANI was the Soke of the Kukkishinden and it is from him that Takamatsu received his training and the scrolls.
Because Shinden Fudo Ryu was not passed on with the Kukkishiden and vice versa, The Takagi Yoshin Ryu was paired with it, so the weapons system and Unarmed system were practiced together, though kept as two schools.
With Takagi Yoshin substituting for the grappling of the missing Shinden Fudo JuTaijitsu, Ishitani still needed a hard "Karate" to take the place of the missing DakenTaijutsu of the Shinden Fudo. This was the inspiration for Ishitani mastering the Gikan Ryu Koppo Jutsu.
GIKAN Ryu was based on Gyokko Ryu, where Uryu studied. However it is a hard KOPPO Jutsu system, developed similarly to how the TODA family developed KOTO Ryu, basing it on Gyokko. This is similar to how different schools and styles of KARATE developed in different regions.
The DAKENTAIJUTSU of Kukkishinden is passed down to us from Ishitani via Takamatsu, these are the techniques listed above
