It was serialized in Shueisha's seinen manga magazine Weekly Young Jump from 2001 to 2002. It was followed by two sequels; Skyhigh: Karma (2003) and Skyhigh: Shinshō (2003–2004). A fourth series, Tenmasō no Sanshimai – Sky High, was serialized in Grand Jump from 2013 to 2014. Skyghigh follows the story of Izuko, a mysterious "Guardian of the Gate" to the Afterlife. Izuku guides troubled souls who pass through, presenting them with three choices: to ascend to Heaven to await reincarnation; to deny their death and wander the earth as a ghost, or to seek vengeance upon the person who caused their death or suffering—but the consequences of that, no matter how justified, is to be condemned to Hell. The series spawned a television drama adaptation which was broadcast on TV Asahi from 2003 to 2004 and a live-action film released in 2003. A live-action film adaptation of Tenmasō no Sanshimai – Sky High premiered in Japanese theaters in 2022.

Izuko is a mysterious gatekeeper to the afterlife. Known as the "Guardian of the Gate", Izuko guides spirits of the recently departed on their journey, sometimes to Heaven, other times to Hell. The decision is theirs and it is not always an easy one. Often the spirit is the victim of a murder or other untimely death. In such case, a soul is offered three options: accept their death as it is and proceed into Heaven to await reincarnation; wander the Earth as a ghost; take justice into their own hands and face the gates of Hell. Most stories involve characters seeking to discover what happened to them and why—with Izuko attempting to guide them on the correct path.
