Well, my wife did not appear this chapter, but off to the side, there's actually a letter from her to the other Seele that you can read (the tsundere ending to it is really cute). From what i've gathered from it she actually became a leader of a valkyrie squad. A combat role is something that's definitely more suited for her, though i imagine her training regime for the rookies she has under her must be hilarious to say the least.
Makes me wonder if they'll eventually reveal that she was the squad leader teased years ago in the Post-Honkai Odyssey, the description they gave back then sure isn't far off from my wife.

I certainly wouldn't mind it. I didn't think she'd work at an orphanage forever; A more combat-oriented role is definitely more fitting for her.
