Armbrust

Armbrust is 20 years old and an Auditor for the Global Union who is sent to observe Éclair and Lumière on some of their missions. Armbrust is calm and collected, although a bit on the shady side too. A veritable ladies' man, he often flirts with the ladies (and sometimes with Eclair). However, he is never seen without his mysterious black briefcase, which seems to have its own powers. Despite his efforts and good intentions, Armbrust is often the target of Eclair's distrust. Mis-translated as Armblast for the English dub, an error that was caught too late to be corrected although it is spelt correctly in the English subtitled version. His name is German for "crossbow".

Later in the series, it is revealed that Armbrust is also an S Class ES-Member whose partner is Pfeilspitze (also known as Mercredi). His ever-present case just happens to be his special ES ability (codenamed "Black Box").
