You don't watch this to understand Buddhism as doctrine. You watch it to sit with a man who walked away from everything because comfort felt like a lie. The animation strips away drama, no triumphant music, no glowing auras, just a person moving through doubt and silence. It's the opposite of what most anime does: it trusts you to find meaning in what isn't explained to you.

Butten Monogatari is a ten-episode OVA that adapts well-known Buddhist scriptures into animation. Its stories center on the figure of Siddhartha, known as Gautama Buddha, and on the earliest period of the Buddhist faith as it first took shape around him. Each installment draws on this scriptural tradition to present the beginnings of Buddhism in animated form.
