Gatekeeper Clown (also known as Gatekeeper Pierrot or Pierot) is a ring ÄRM of the most powerful Dimension type that summons people from another world into MÄR-Heaven. When activated, it conjures a literally cross-eyed clown before the summoned and determines the number of passengers by a roll of dice. After fulfilling its role, the ÄRM will break. Bequeathed to Alan from Queen Diana (1st war), and to Alviss from Gaira (2nd war).
