More anime with "tantric Buddhism" like Kujaku O/Peacock King/Spirit Warrior where they do esoteric practices? The Boxer's Omen(1983), Bewitched (1981) are equivalents in hongkong cinema which I am looking for. Wondering if there were any anime with same themes. Not looking for Feng Shui, Shintoism stuff but shoot your rec anyway.

Utsunomiko is about Shugendo

Doomed Megalopolis is all about onmyoji and has a bodhisattva(Guanyin).
