Mercredi

メルクルディ

Mercredi (French for Wednesday), despite being only 13 years old, serves as Eclipse's Private Secretary and can be regarded as her "right-hand girl." She is exceptionally skilled at data gathering, with abilities that nearly rival those of a computer. This role also allows her to spend time with many ES Members, and she is friends with Éclair and Lumière. Mercredi is also adept at making tea, typically preparing a batch for Eclair and Lumiere after each of their missions. She goes missing when the GOTT towers are destroyed and is presumed dead; however, she reappears in the rebuilt GOTT building without her usual uniform. In reality, her true codename is Pfeilspitze (German for "arrowhead"), and she has been operating as a double agent within GOTT for her partner, Armbrust.
In Kiddy Girl-AND, she operates under a new name: Hiver. She has also become the leader of GTO.
