As every contestant knows, the head of the 7asa7ees gang caused unforgettable chaos in HIAST CPC 2024.

Since that day, the 3ara3eer gang devoted their lives to stopping the 7asa7ees from causing more trouble for the contestants. They trained in secret rooms, guarded old archives, and watched every problemsetting meeting from the shadows.

This year, destiny brought them to the same table again.

The head of the 7asa7ees, Fofo, entered the problemsetting room with a calm smile, holding a mysterious scroll covered with strange symbols. With great confidence, Fofo suggested a 7as7ous problem.

The room became silent.

Bisseh, the head of the 3ara3eer, stood up and rejected the idea at once. The air grew heavy. Papers flew from the table. The lights flickered. Fofo's smile disappeared.

A battle began.

Bisseh fought bravely, but Fofo was a true 7as7oos. With terrifying speed, Fofo defeated Bisseh and left him fallen among the broken chairs of the problemsetting room.

Then Al-Coach Habbab stepped forward.

Everyone knew Al-Coach Habbab had strong muscles. He believed he could take revenge for his leader, and for a moment, even Fofo looked worried. Habbab charged forward, shaking the whole hall with every step.

But Fofo raised one hand and whispered the forbidden spell: $$$$$$\texttt{7as}$$$$$$

The spell struck Al-Coach Habbab directly, and he fell before reaching Fofo.

Far away, 3atori, Anous, and Moufless saw the sky turning dark above the battlefield. Without hesitation, they climbed aboard their Jamalocopter and went straight to the fight area.

What happened next was remembered as one of the wildest battles in problemsetting history. The Jamalocopter roared through smoke and lightning. Moufless held the route steady through the storm. Anous dodged cursed statements. 3atori broke through waves of 7as7ous energy. Fofo answered every attack with another spell, another trap, another impossible twist.

At last, 3atori was cornered. His strength was fading. Fofo prepared the final strike.

Just before everything ended, 3atori raised his hand and cast the ancient spell: $$$$$$\texttt{3rr}$$$$$$

The battlefield shook.

Fofo was defeated.

But the story did not end there.

Sneakily, the 3ambaloos entered the fight area while nobody was watching. They moved Fofo to the hospital, where he is now healing and preparing for another battle.

To be continued.
