Santen Kesshun (三天結盾, Three Sacred Links Shield; Viz "Three-God Shield") is a technique used by Orihime Inoue.
Santen Kesshun is a defensive technique which allows Orihime to repel attacks. Orihime calls out the names of Hinagiku, Lily, and Baigon, who form a triangle, creating the foundation of a shield, before declaring the name of the technique, followed by the phrase "I reject" (私は拒絶する, watashi wa kyozetsu suru). This process serves as her kotodama, which activates the ability.
The triangular shield allows her to repel the "outer shield". The shield is raised between her and her enemy, and it repels the attack before it hits its target. It can also function as an airbag of sorts, allowing Orihime and anyone else nearby to survive a potentially lethal fall unharmed. Orihime is later able to shape Santen Kesshun into a dome-shaped barrier large enough to easily hold herself and other individuals.
