As kids, the Nanba brothers saw a mysterious light in the night sky and swore they would go to space together. By 2025, younger brother Hibito has kept that promise, becoming an astronaut chosen for Japan's first long-term lunar mission. Older brother Mutta, meanwhile, has just been fired from his car-company job for headbutting his boss. Jobless and adrift, Mutta receives a single email from Hibito that reignites the dream he had buried. Volume 1 launches a grounded, heartfelt story about a grown man daring to look up at the stars again.
