Guardian Tales is packed with secrets waiting to be uncovered. Achieving 100% completion means not only conquering the main storyline but also diving deep into hidden stages and secret quests that offer unique rewards and fascinating lore. In this guide, we’ll walk you through the steps to unlock every hidden stage and clear all the hidden quests that might be holding you back from mastering the game.
Unlocking Hidden Stages and Quests
1. Unknown Dungeon (World 1)
To access the Unknown Dungeon, head to Stage 7 and enter the Maze Forest. Follow the precise sequence: up, up, down, down, left, right, left, right. Once you complete the sequence, interact with the mysterious portal to unlock this secret stage.
2. Lazy Fairy Quest (World 2–5)
Unlocking the Lazy Fairy stage begins in Stage 2. Visit the hidden area indicated by fluttering butterflies and obtain the map that unlocks the stage. However, the real challenge is completing the Lazy Fairy’s quest. You must collect three comic books:
- The first comic, “The Legend of Hyper,” is found inside a house in World 2 Stage 2.
- The second comic is in World 3 Stage 5—enter the room, solve the torch puzzle by lighting only the left and right torches, and speak with the otaku (make sure you have 10 SNS followers).
- The third comic, “The Chronicles of Caden,” awaits you in a secret cave unlocked via a map given by a pot man in World 5 Stage 5.
Return to the Lazy Fairy with all three books to complete the quest.
3. Invader Supply Storage (World 2)
To unlock the Invader Supply Storage, first acquire the hook shot from World 3 Stage 6. Use this hook shot to cross over to the other side and speak with the designated NPC. Then, revisit Stage One’s Engineer Rescue area. On your second entry, a tan character will request that you rescue an engineer, which will then unlock this hidden stage.
4. Dual Personality Maid Quest (Stage 4 / World 6)
In Stage 4, speak with an old man who triggers a quest. After clearing that stage, return to World 6 Stage 3 and meet the Dual Personality Maid. Talking to her will unlock another hidden stage. Complete this follow-up stage to finish the quest.
5. Viper Clan Dojo (World 5)
To access the Viper Clan Dojo, equip the Viper Clan uniform on your Knight (available from Stage One). Then, with your Knight leading the team, head to Stage 7 and proceed to the designated location to unlock the dojo stage.

The Arch Fiend Seal stage requires you to pay respect to five statues located across stages:
- Statue 1 in Stage 1

- Statue 4 in Stage 4
- Statue 5 in Stage 5
After showing respect at all five locations, a sword will appear, guiding you to the hidden stage. But before proceeding, complete the Witch and Potion quest in World 3 Stage 4 to obtain the cookbook. Show the cookbook to an elf in World 7 Stage 5 and secure the gem bug, which finally unlocks the Arch Fiend Seal stage. Once cleared, you’ll receive a special stew needed for further quests.

After finishing the main story of World 3, revisit Stage 3 and present the stew you obtained to the Favi and Lavi statues. This act completes the Statues of Bravery Quest.

13. Invader Janitor (World 12)

14. Man with a Wolf Mask Quest (World 14)
In World 14, start in Stage 5 by picking up a special potion. Speak with two NPCs to confirm you’ve been scammed, then head to the designated area and wait for a cutscene to finish. Once complete, talk to the sheep girl who will assign you a quest. Enter Stage 6, visit the specified location, and complete the quest to obtain the best figure needed to start the next part of the challenge. Finally, provoke the kid to use his last coin on the gacha machine to get the figure he desires, thereby completing the quest.
