The Chūishiki (中位式, Medium Style) was the first form of Zanjutsu combat which was initially taught by all three spiritual realms, specifically Soul Society, Horiwari and Heisekai. Following the events of The Collapse the only place one could study this form was the Reikai, which housed Kentaro Hiroshi's new Shinō Academy, which was ran by Head-Instructor Shiju Shūdō and his Second Ashido Kanō.
