My Magical Career at Court: Living the Dream After My Nightmare Boss Fired Me from the Mages' Guild! Volume 5 by Shusui Hazuki

Spell Boost! Less than a year ago, Noelle was stuck in the remote countryside, enduring the daily grind at a local mages’ guild. But since getting fired, she’s risen through the ranks of the prestigious Royal Court Magicians’ Division. And it’s no wonder she’s doing so well, after performing feats like befriending the Fairy Queen, exposing the nastiest aristocrat in the kingdom, and saving the third prince’s life!

But what’s this about a Seventh Unit? All of a sudden, the division is launching a new unit with Noelle and her old friend Luke in charge. Noelle is eager to have subordinates to mentor, but the new unit has two orders of business: dealing with pressure from court nobles and trying to work out who is manipulating events behind-the-scenes. It looks like Noelle’s new position will come with plenty of work...

And who knows—maybe Luke will finally make his move!
