When Azalia released her killing intent, Zenoa and everyone in the place, including Prince Ozkar, were shocked after feeling the terrifying pressure from her. They had never seen Azalia exert such power.
The waiters and employees in the cafeteria were terrified under tremendous pressure. They still dared to warn Prince Ozkar and Sintaro when the two were about to fight, but since Zenoa took action first, they didn't need to do anything. But this time, the cafeteria employees didn't dare approach the table because they sensed the danger from Azalia.
Zenoa trembled after feeling Azalia's killing intent. He didn't expect that a student would have such pressure. On the other hand, while Princess Melkia and everyone else at the table were terrified, Prince Ozkar was even more enthusiastic about making Azalia his own. Only a beautiful and strong girl deserves to be his companion, and Azalia fulfills his ideal girl's criteria.
