Please Save My Earth

The series was adapted as a six-part original video animation (OVA) in 1993. A sequel manga, Embraced by the Moonlight, was serialized in the bimonthly Hana to Yume as well as the special edition magazine, Hana to Yume Plus. It has since been followed by I Sing with the Earth. Both the anime OVA and manga are licensed for distribution in North America by Viz Media. A live-action drama adaptation will be streamed worldwide on Amazon Prime Video in Q4 2027.

The story follows high-school student Alice Sakaguchi, her seven-year-old neighbor Rin Kobayashi, and five other students who share recurring dreams about alien scientists stationed on the Moon to observe Earth. After Alice has one of these "Moon dreams", she joins classmates Jinpachi and Issei in searching for the others who dream as the remaining scientists. What begins as a "game" becomes something darker as the group realizes the dreams are suppressed memories of tragic past lives. They now must confront those memories while keeping old rivalries, jealousies, and betrayals from consuming their present lives.

Before starting to work on Please Save My Earth, Saki Hiwatari was exhausted by drawing her previous series Akuma-kun and wanted to create something that would feel "healing" for her to draw. She observed the magnolia tree at her workplace and started off from there. However, when working on the script, she added more suspense. She described working on the series as a result of her fighting with herself over whether she should draw something serious or something funny. Initially, the series was only supposed to last one year. The series mixes dramatic storytelling with comic relief. Many of the jokes in early volumes of the series refer to 1980s anime and manga. Critic Jason Thompson notes that the story becomes more dark and adult-themed from volume 9 on. The visual style, for example of the character design, changes throughout the series. The character design of Issei's sister Kyoko was influenced by Osamu Tezuka and is a homage to classic style of manga artists such as Miyako Maki, Macoto Takahashi, Hideko Mizuno, and Shotaro Ishinomori.

Written and illustrated by Saki Hiwatari, Please Save My Earth was serialized by Hakusensha in the monthly magazine Hana to Yume from December 20, 1986, to May 20, 1994, with its chapters collected in 21 tankōbon volumes. The series was later reissued in 12 bunkoban volumes in 1998; and again in an A5 format edition (wide-ban) of 10 volumes in 2004. It is licensed in English in North America by Viz Media, with all volumes translated. The series has also been translated into French; German; and Spanish.
