Nintendo released information on Marni, or Madeline, as she will appear in the Fell Xenologue DLC for Fire Emblem Engage.
The Fell Xenologue DLC will be part of Wave 4 of Fire Emblem Engage’s Expansion Pass.
Aside from voicing Marni in Fire Emblem Engage, Aoki also previously appeared as Riina Tada in The Idolmaster CInderella Girls and Touko Aozaki in Witch on the Holy Night.
Instead of being an enemy and one of the Four Hounds, she is Alear’s ally and one of the Four Winds.
