Paper Mario: The Thousand-Year Door is an RPG made by Nintendo and is the second game in the Paper Mario series following Paper Mario for the Nintendo 64. It incorporates a world made of paper and turn-based battles, much like its predecessor. In it, Peach asks Mario to help find a treasure hidden in Rogueport. When he arrives, she is missing as usual, and he must collect 7 Crystal Stars and open the Thousand-Year Door to save her and collect the treasure.

In this TAS, Reya gathers all Crystal Stars and defeats the final boss in record time, while abusing glitches that are detailed in the author's comments.
