Retreat

The resulting explosion of multiple missiles exploding was so loud that almost half of the guards clenched their teeth while clutching their heads in pain. The shockwave also caused chaos on the invading party's formation, making their advance come into a halt. 

A huge grayish mushroom-like smoke can be seen after the explosion and more than twenty percent of the invader's soldiers were killed as a result. 

"He did it!"

"Good job, sir Zero!"

Some of the academy's guards cheered with joyous tones as they helped their injured comrades.

Demetrio frowned deeply while peering at a certain location. He saw a figure of a man escaping towards the academy. Demetrio's expression turned cold in an instant after seeing the sorry plight of the man.

"Kenji, Leonhart, get Zero back here!" He ordered in a solemn tone of voice.

"Understood!" Answered the two vice headmasters in unison before they vanished from where they stood.
