Azul was observing the situation, everything was going according to his plan. Everyone was enjoying the event, some students were dancing with their friends and others were eating but most importantly, everyone got interested in the magical objects exposed by him, just like he planned. After the students spent hours dancing they decided to leave, exhausted. Everything seemed normal till they realized they couldn't leave. Everytime they tried to leave Mostro Lounge they were pushed inside by a strange force. People started to panic and when they demanded an explanation from Azul he just said

You can't leave? Of course you can't since the exposed objects are cursed. If you want to leave each one of you will have to make a wish of mine come true.You got what you wanted so it's only fair I get something as well

and so people had to obey him, but they got freed after giving Azul what he wanted. When it was your turn he simply said

As for you, you won't leave this place. You're my wish, Angelfish
