Put to the test at every turn! Mai and the others have been enjoying their hard-earned free time after completing the Blue Event. Of course, that goes right out the window when maintenance suddenly ends and catches everyone off guard—and a bunch of Nightmare Conquerors’ Club members even lose Respawn Penalties! Once they max out the club budget to buy back their senses and limbs, Mai and her teammates jump into the game to top up their resources. Ready to grind, they enter a spooky mansion with a door that no players have been able to open. Alongside the game’s top rankers, Mai’s Raid Team will get its chance to unravel the mystery behind the sealed door!
