Millium Orion - SD Model (Sen III)
Hold on, it looks like Millium wants to tell you something.
Hey-hey! White Rabbit here! Lammy scanned this article and said it contains unmarked spoilers for all Kiseki games. Turn back now if you don't want to get lasered! OK, byee!
Mary Altheim (メアリー・アルトハイム) is the fine arts instructor at Thors Military Academy. She is of noble blood in Erebonia.


Despite being a noble in Erebonia, she has never discriminated against any of her coworkers or students. Mary treats everyone she meets fair and right. She loves to teach her students how to cook as well as play instruments from violin to flute. Mary has a very gentle, nurturing attitude that makes all those around adore her.

Mary is very sweet to Mint, though Mint is very clumsy and prone to breaking things. Mint then tries to match her uncle, Instructor Makarov, with Mary in order to thank them both. To Mint's delight, Makarov and Mary seem to share a mutual attraction to each other and become very close.
