500000000 years button

📖 SYNOPSIS

The anime centers on three siblings: five-year-old Tonio, fourteen-year-old Jaibi, and seventeen-year-old Suneko. Their father requires expensive medical treatment, and they are struggling to afford it. Their financial woes take a dramatic turn when they encounter a person offering the "500 million year button." This button promises a million yen upon activation, but the price is a staggering 500 million years spent alone in a completely empty space. The catch? Upon the completion of this unimaginable sentence, the user's memory will be erased, effectively making the experience instantaneous for them. The siblings must grapple with this impossible choice and the implications of such a deal.
