Mr. Neonbag

Mr. Neonbag (Not his actually name, just something Baam calls him for some reason) is a test assistant that helped administer Yu Han Sung 's Door Test. He and his fake team mixed in with the Regulars in order to give a hint to all the teams before they took the door choosing examination.

The hint was that in order to pass the test, whatever had to be done in the room must be finished before 5 minutes.

The purpose of the hint was to help weed out the suspicious and untrustworthy test takers as they are considered dangerous to the tower.
