A thousand years after psychic humans wiped out those without power, Saki Watanabe grows up in a peaceful village where children train to control Juryoku, the ability to shape matter with thought alone. During a summer camp, Saki and her friends Satoru, Maria, Shun, and Mamoru uncover a forbidden archive that reveals how their ancestors' war actually unfolded. A monk seals their powers as punishment, leaving them stranded in the wilderness and dependent on the intelligent, rat-like Bakenezumi to survive. This manga adaptation compresses Yusuke Kishi's award-winning novel, keeping its central mystery about what really happened to the pre-psychic world.
