'Of course, he figured his mentor was definitely giving Amadis and that other "little junior sister" plenty of private lessons on the side.'
The Undead System was in decline, and their mentor, Annabella, shouldered the hope of reviving their school. It was impossible for her to bet everything on Lynch alone.
This was especially true for the junior sister Lynch had yet to meet. His mentor had mentioned her several times in her Magic Letters, praising her astounding talent and saying her aptitude for the Undead path was "in no way inferior" to her own back in the day.
Therefore, the students his mentor was currently focused on cultivating were likely him—Lynch, Senior Sister Amadis, and the little junior sister. One from each year, perfectly forming a kind of talent pipeline.
But Amadis just waved her hand. "What's there to congratulate? It's just a thankless, grueling job."
