Shiten Kōshun

is a technique used by Orihime Inoue.

Description
Combines both the offensive and defensive properties of Orihime's Shun Shun Rikka. Orihime summons Hinagiku, Lily, Baigon, and Tsubaki before calling out the name of the technique, a process which initiates the usual incantation for invoking her powers. She follows this with her usual kotodama,. When Orihime first demonstrates this technique in front of Ichigo Kurosaki, she has passed the stage of needing to verbally summon her abilities, and can do so with the incantation.

As Hinagiku, Lily and Baigon form Santen Kesshun to protect a target from attack, Tsubaki is integrated into the middle of the pyramidal shield to combine their abilities. When the shield receives an attack, Tsubaki disperses the resultant force as a concentrated explosion, which is automatically returned along the attack's opposing trajectory.

Trivia
While initially portrayed as a triangular shield, Shiten Kōshun is shown as a square shield when Orihime uses it in The Thousand-Year Blood War anime adaptation.
