Aka Night

Aka Night (赤夜, Aka Yoru) was formerly a magics and artillery teacher to the students at the Fioren Guard Academy, tasked with teaching them about magic, how to develop their own and use it, and how to use weapons, namely guns. She left the academy due to unknown reasons and instead joined a guild to further her magical abilities, believing to not tie herself down anymore to any permanent job such as teaching any more. Whether she plans to return to teaching is unknown.

Aka is also the heir to the Night Family, and the older sister of Gin Night. She negated her responsibilities and duties to the Night Family a long time ago due to her self-blame that Gin had "died" because of her.
