Unreturned souls and whispers in the fog…
Join the Mystery Investigation Squad to trace the clues of missing persons and unveil the sinister secrets of the fog!
▶ Save Kaia Island swallowed by the fog!
A mysterious fog is spreading across Kaia Island! With days passing, the fog grows thicker, dangerous Monsters appear, and more people have gone missing.
Receive the Tiger Gun Weapon from Capt. Tin to fend off dangerous Monsters, and along with the Mystery Investigation Squad, discover the true nature of this eerie fog to save Kaia Island!
※ Defeated Monsters drop Mysterious Keys, usable in the Minigame “Operation: Infiltrate Danger Zone”.
▶ Trace the Missing Investigators’ Clues!
The investigators who were uncovering the fog’s mystery have gone missing!
Explore Downtown to locate the missing investigators’ items, and you’ll uncover the truth behind the mystery and win special Rewards.
Complete all puzzles to earn the Outstanding Investigator badge and the Fog Monster Profile!
▶ Minigames – Operation: Infiltrate Danger Zone
Use Mysterious Keys to search for hidden Investigation Unit Emblems, and obtain the Investigation Unit Tactical Suit costume and a KISA Recon Helicopter mount!

Finding an emblem lets you advance to the next row; discovering “ERROR” ends the game, but you keep all emblems found so far.

※ The Minigame "Operation: Infiltrate Danger Zone" is available until [July 31, 2025 23:59 (UTC)].
