There are 6 Forms: Basics of the Spear (表之槍 Omote no Yari), and 2 Forms: Secret forms (Hiden no Yari). I would again make the observation that when comparing schools, the spear found in complete schools tends to be of the garden variety, where as the spear of specialised schools tends to have a cross piece or be unusual in some way.
As this school is of particular interest I have included a detailed look at the first 6 Kata (I have not found any material on the other two). My preference is to use the Hombu players for such things however with the limited material available the breakdowns have been taken from another source, which I will link at the bottom, and so should not be taken as definitive (although I have made an effort to compare to Otake’s book and would say it more or less matches except in Denko no Yari the spear arises on the first thrust in the book). Reference should be made to one of Otake’s works for further information.

The original demonstration is shown below, thanks to those involved for posting as the spear is often overlooked.
