The Legend of Heroes: Trails of Cold Steel IV has a whole bunch of returning characters, and Alisa, Alberich, Irina, and Kreuger (Sharon Kreuger) are the next to receive an re-introduction. [Thanks, 4Gamer!]
[Note: It should go without saying that there may be some spoilers below, proceed at your own risk.]

Black Alberich is the leader of the Gnomes, and uses the combat shell Zoa Balor.
Irina Reinford (CV: Yuko Sumitomo)

Kreuger, The Severing Chains (CV: Yukana)
Enforcer No. IX from the mysterious Ouroboros society. She considers her contract with Irina “complete”, and returns to Ouroboros. Now she faces Alisa as an enforcer.
