In Mystery Quest, known in Japan as Hao-kun no Fushigi na Tabi (ハオ君の不思議な旅), the player is Hao, an apprentice wizard who finally has a chance to prove himself. The Great Wizard has challenged Hao to seek out his four hidden talismans, which he has placed in four different castles.

Hao has a magic attack which can be upgraded once in the game, and can shoot left and right as well as jumping and upward angled shots. There is also a limited variety of items that can help Hao progress through his quest.

In this run, TASeditor runs, jumps and shoots his way through the castles and completes the quest in under 15 minutes.
