Ultra Heaven (ウルトラヘヴン, Urutora Hevun) is a Japanese manga series written and illustrated by Keiichi Koike.

It was serialized intermittently in Enterbrain's seinen manga magazine Comic Beam starting in its July 2001 issue and has been collected into three tankōbon.

He goes to a pump bar and asks for a dangerous mixture of drugs, but instead the maestro gives him a special called "Nova Express," which simulates the experience of dying.

Nobody seems to have Peter Pan anymore, but there are rumors of an even stronger drug that is the most powerful hallucinogen invented.

Kabu tries the drug and has a nightmarish trip where he cannot separate his body from objects around him and he ends up killing two sanitation officers.

An agent shoots Kabu in the head and he enters a trip that lands him in a hygiene department recovering from a drug overdose.
