Asobot Senki Gokuu

Four years from now, the world faces severe environmental collapse, with massive forests lost and deserts expanding. In response, people migrate to the world of Meshichi to coexist with Anbots. Sanzou, a mysterious young man, and Gokyuu, a powerful and notorious Anbot, cross paths. They are joined by Tongoh, a drinking-loving Anbot; Jou, a skilled mechanic; Suuji, a female Anbot thief; and Mioto. Together, they embark on a journey toward the East, heading to the land of the sun's origin.
