Humanity has spent a century searching for planets suitable for life, but never found one. Then the moment the protagonist's Golden Explorer sets off, it discovers a habitable planet, only for the color-blind captain to press the wrong button and blow it up. After that, the crew goes on to destroy one planet after another. The heroine isn't driven crazy just by her captain, who slacks off and loves shifting the blame. There's also the cleanliness-obsessed, obsessive-compulsive researcher; the chatty, hopelessly romantic courier; the timid minister of military affairs; the blood-fainting, forgetful doctor; the chuunibyou mechanic... In short, their chaotic, lively interstellar journey begins.
