Senjutsu

Senjutsu (仙術, lit. "Mystic Arts") is the name of a Chinese martial art of mythical and legendary proportions. It is said to have been used by the immortal mountain hermits of Taoist myth, and is centered on the exercise and mastery of one's ki.

One such character, Oro, is a master of Senjutsu (called a Sennin) that appears as a playable character in the series.

Description
Mastery of these legendary practices were said to grant the practitioner fantastical powers; such powers include superhuman strength, prowess and agility, as well as longevity and/or effectively immortality. A Sennin can manifest their ki into corporeal form with ease and use it to perform telekinesis; they can also survive and withstand environmental and atmospheric conditions too extreme for a normal human being.
