Ultra Heaven(2001)

In the future, any mood you want is just a pump away. People flock to legal “pump bars,” where licensed medical professionals, known as bar doctors, prescribe their customers the perfect pharmaceutical blend.

But when the standard dosage isn’t enough, our protagonist, Cub, turns to an unauthorized source. The results have to be seen to be believed.

Rendered in a richly-detailed, clear-line style, this psychedelic sci-fi manga tears apart the basic fabric of reality. What is the truth and what is a dream?
