Only those who have the fighting spirit to become stronger can become part of Rossweisse's disciples. Since her disciple's boyfriend had absolutely no desire to become one of her disciples, Rossweisse decided to forget about the stupid question she had previously asked him.
As a master who had countless disciples, Rossweisse did not lack disciples to teach. But talent was the most important thing in Rossweisse's principles. Therefore, Rossweisse felt disappointed when she heard Lucien's refusal to become one of her disciples.
Now, Lucien was by no means a weak human like ordinary humans. Lucien's current strength allowed him to fight against every one of Rossweisse's disciples. For that reason, Rossweisse deeply regretted not being able to take Lucien as her disciple.
