Chinto is according to the translation of Ohtsuka sensei's Kata book "the end" and is therefore traditionally taught as the nineth Kata. Prior to Chinto you practice (besides Pinan) Kushanku, followed by Naihanchi and Seishan. Naihanchi and Seishan are what is nowadays called Internal Kata and Chinto is an application of that. Naihanchi is Tanren gata, where you learn how to use your body. The first part of Seishan is an extension of that and the second part of Seishan where movements are executed fast, is considered application. Chinto is sees as the next and 'last' step.
In the video, you will see a walkthough with a sideview. During slowly executing Chinto I mention keypoints that you can pay attention to during your training. Below you find Chinto demonstrated picture by picture, where I mention the names of the stances and techniques used.
