A cat climbing up Mount Nadera seemed to be in great pain. His name was Hijiriyama, and he’d gotten a stomachache after eating curry rice. Another cat offered to help him find a way to cure his stomach problem, and along the way, they met more feline friends who joined their journey. *It was published in Monthly Magazine Garo (月刊漫画ガロ) on December 1973*

In a surreal, post-apocalyptic Tokyo, a human and a humanoid cat wander through the city’s empty streets, reflecting on the fall of mankind and the rise of a strange new order. As they talk about extinction, memory, and the absurdity of modern life, their quiet walk becomes an eerie allegory of civilization’s decay and renewal. The story distills the experimental tone of early Garo, blending existential dialogue and surreal imagery into a haunting vision of a world where humanity’s reign has quietly ended. *It was published in Monthly Magazine Garo (月刊漫画ガロ) on August 1973*
