Three kids staring at a button that trades 500 million years of nothing for money they need right now. The show understands that desperation doesn't philosophize, it just chooses. The animation is bare and the pacing stumbles after the halfway point, but what lands in those early episodes, the arithmetic of suffering, the way hope and horror look identical when you're broke, stays with you longer than shows that try twice as hard to matter.
Three siblings face a desperate choice when their father's medical bills pile up with no way to pay. A stranger arrives with an offer: press a button, receive a million yen instantly, and spend five hundred million years alone in absolute nothingness. When those centuries conclude, your memory resets and you return to the moment before you pressed it. To you, no time passes at all. The money is real. The isolation is real. Only your awareness of it vanishes. Suneko, the oldest at seventeen, considers the weight of such a transaction. Fourteen-year-old Jaibi wrestles with what it means to sacrifice something you'll never remember experiencing. Young Tonio, just five years old, doesn't fully grasp the horror of the choice before them. The button waits. The premise seems clean, almost logical. But the anime asks harder questions: What does it mean to suffer if you'll never know you suffered? Does a choice still matter if the cost erases itself from memory? How far will desperation push you toward the unknowable?
