The Reaper who had his own plans for Azzy wanted him to learn the meaning of delivering true justice instead of just acting on emotions. And being the president of the disciplinary committee can be the first step to achieving that.
Getting convinced by the Reaper, Azzy threw away all the thoughts of Leo's whatever schemes and put forth his hand towards the girl. "Let's work together."
Matilda shook his hand, "pleasant to be working together."
In reality, after serving as the Vice-president for two years in a row, Matilda wanted to serve as the president once Leo and the other tenth graders graduate.
She knew that she had to be at least rank 5 to achieve that or at least have a rank 5 above combat level to control the students.
With her soul power just above 92000, she thought she would be able to break through to the next rank before the next semester. However, she didn't expect Leo to resign and then, propose Azzy's name as his successor.
