Maiden of the Aqua

Maiden of the Aqua is a level 4, water-type aqua monster. She is one of the few female monsters whose bust size was not reduced in its TCG artwork. Her card effect is: "As long as this card remains face-up on the field, the field is treated as 'Umi' (however there is no increasing or decreasing of ATK/DEF due to 'Umi''s effect). If there is an active Field Spell Card on the field, this effect is not applied."
