Signum Yagami (八神シグナム Yagami Shigunamu) is originally a Wolkenritter in the primary continuity first introduced in Magical Girl Lyrical Nanoha A's. In the INNOCENT spin-off series, she becomes a family member of Hayate Yagami, originally her mistress.


In the game, she is sometimes referred as Coach Signum (シグナム師範 Shigunmu Shihan) as she is a kendō coach besides working at Yagamidō.


Signum is a polite and calm person.


Signum is a sports university student and formerly a senpai of Mituki Scaglietti in the high school. Being a kendō rank-holder, she also works as Assistant Kendō Coach at the Kusama Ittō-ryū Dojo. For unknown reasons, Signum does not need to do housework in the Yagami family except for strength works, like the father of the family.[1]

Signum has not played Brave Duel until the Team Yagamidō is formed when the first Brave Duel Grand Prix approaches.
