Wednesday's assistant mercredi is an exceptional young girl with remarkable skills in data gathering and analysis. at just 13 years old, she serves as éclair's private secretary and is often referred to as her "right-hand girl". despite being so young, mercredi possesses abilities that are almost computer-like. she also enjoys spending time with the other members of es and has formed close friendships with éclair and lumière. mercredi excels at making tea and is known for fixing batches for her friends after their missions.
however, tragedy strikes when the gott towers are destroyed and mercredi goes missing. she is presumed dead but eventually reappears in the newly built gott building without her usual uniform. it turns out that mercredi's true codename is pfeilspitze (german for "arrowhead") and she has been working as a double agent inside the gott on behalf of her partner, armbrust. in addition to this, mercredi has also taken on the leadership role of gto.
