5-Okunen Button

Synopsis

Pressing the 500 million year button causes a million yen to appear. In return, you must endure 500 million years alone in an entirely empty void. However, once those 500 million years conclude, your memory is wiped clean, and you return to the exact moment you started. To the one who pressed it, the whole ordeal feels like an instant—a million yen gained in no time at all. Five-year-old Tonio, fourteen-year-old Jaibi, and seventeen-year-old Suneko are desperate for money to cover their father's hospital treatment. Then, before the three siblings, someone appears holding the "500 million year" button... A brand-new animation based on the cult classic "500 Million Year Button" story from the Minna no Tonio-chan series!
