The Brilliant Healer's New Life in the Shadows: Volume 5 (Light Novel) — Sakaku Hishikawa

After a fateful meeting with his late mentor’s projection, Zenos realizes he’s gotten this far in life because he had a teacher. With the encounter spurring him on, he and the demi-human leaders decide to start a school in the slums. Unfortunately, they quickly encounter a roadblock that seems insurmountable: How can they provide the children of the slums with proper education when none of the leaders have received formal education themselves? In a lucky twist of fate, a familiar face brings with it an opportunity for Zenos to teach healing magic at a prestigious academy. Saying yes could be the solution to their problems—nothing beats hands-on experience, after all! But on Zenos’s first day of classes, it quickly becomes apparent that this assignment isn’t quite what it seems. Might this be the solution he seeks? Or will it just add to his never-ending list of problems?
