ぼくの地球を守って [Boku no Chikyuu wo Mamotte / Please Save My Earth]

A lyrical and intricate science-fiction romance from Hakusensha, Please Save My Earth is the magnum opus of creator Saki Hiwatari, spanning seven years and 21 volumes. The story follows a group of Japanese high school students who begin sharing the same dreams—vivid, fragmented memories of a lunar base and a team of scientists from an alien civilization. As they piece together these past lives, they uncover a tragic love story and a cosmic mystery that binds them across time and space. Hiwatari’s delicate, emotional storytelling and elegant art make this a landmark shōjo series, celebrated for its ambitious blend of reincarnation, psychological depth, and tender character drama.
