Teishiha

Overview
Teishiha is a common Reiseī technique that is actually the very first technique a user of Reiseī must learn before proceeding. It outlines the basis of all Reiseī based attacks. The user focuses their reiatsu at a particular part of their body to defend against an oncoming attack. It sounds simple, but the trick is to know how much of one's reiatsu to focus. Too little, and the attack goes through. Too much, and the backfire can be catastrophic.
