In a future where environmental collapse has reshaped civilization, humans have relocated to Meshichi to coexist with the Anbots, a race of artificial beings. When a mysterious young man named Sanzou arrives in this strange new world, he crosses paths with Gokyuu, a reckless and powerful Anbot with a reputation for chaos. Despite their rocky introduction, the two form an unlikely partnership and set out on a journey eastward, chasing rumors of a legendary land where the sun is born. Along the way, their traveling party grows to include Tongoh, a booze-loving Anbot with surprising depth, Jou, a gifted mechanic with practical solutions for their obstacles, Suuji, a cunning thief with her own agenda, and Mioto, whose connection to the group remains ambiguous. As they traverse this transformed landscape, the road tests their bonds and forces each character to confront their own secrets. Equal parts comedy and genuine peril, the series finds humor in the chaos of their traveling chaos while building toward questions about what humanity's future really holds.
