The events that transpired, as well as the fact that his daughter had barely escaped falling under the guardianship of a heartless monster, did not bring Lionel any joy. He had sent Leila to what he believed was a safe place. Instead, she was forced to confront one of the ugliest sides of humanity – something he had hoped to protect her from. He had not expected such a level of sheer incompetence, the inability to even check the background of one of their instructors, from an academy founded by the royal family.
Nevertheless, it was already too late to do anything; what had happened would never be forgotten, and Leila's world would never be the same. She could no longer turn a blind eye to all the terrible events taking place in Lafrenia, convincing herself that they were happening somewhere far away, in another world. Along with Dion and Ignatius, the naiveté of the time mage had also died. There was nowhere left to run from reality, which meant she had to be prepared. Carvia's evil deeds, after much reflection on Leila's part, did not deter her from wanting to study magic, but instead became an additional motivation for her to understand this science, at least on a theoretical level. The sorceress's actions clearly demonstrated how destructive, dangerous, but also convenient a tool magic could be in the hands of even a somewhat resourceful person. This was equally impressive and frightening. Therefore, she needed to know what else people like the "Grandmaster of Sakuramorii" were capable of. At the very least, she needed to know how to resist their spells. There was no turning back.
After much persuasion, Lionel finally gave in to his daughter. It was difficult to deny the progress she had made in just one month, as well as the fact that NAILS would be the best place to prepare her for the dangers described. And if he couldn't dissuade Leila, the best solution was to teach her everything he could during the time they had together. Lionel may not be Thyme Chaber, but he would certainly be a better teacher than the crazy witch.
