Orlando, an otaku, activates the Treasure Hunting System through a dream, turning an old wardrobe into a time portal. He meets historical legends, discovers treasures, and gains fame through his best friend's live streams. His success draws the attention of enemy nations, who summon Miyamoto Musashi to attack him. A general from the past aids in the battle, while a hidden ally thwarts ninja assassins. Through his adventures, Orlando uncovers the system’s true purpose, collects antiques, and ultimately saves New Mayland from future danger.
