The picture above shows initial portion of the the 'Ryōi Shintō-ryū Kyuyo no maki' (良移心当流 九要之巻) document, which refers to the 'nine key points' (or cornerstones) of the style. This was traditionally included as part of the 'Menkyo Kaiden' (免許皆伝 - full transmission) and 'Kumiuchi Gokami Mokuroku' (組討後上目録) advanced grappling catalogue) levels.
