It's A Pirate! Let's Harass Him Then!
Their fleets were much more organised, and well-trained than the ones of this world. Not to mention there were many diverse types of spaceships in the Hescos fleet, with more capabilities like flying speed and firepower.
Yet Hye knew the ship he was using wasn't paling in comparison to the best small ships the Hescos had. As the fight was wild and crazy, all ships were moving too fast, making him unable to see anything in great detail.
If he did, he'd be surprised that many of the ships he marked as good were all like his. And if he knew that, he'd grow fanatic about hunting and hijacking them. And later on, when he'd learn about this, he'd deeply regret what he missed.
The situation kept going nicely for him, while the space pirate forces started to breathe. The moment the two forces returned to hunt each other down, the pirate ships started to pull distance, gather up, and form a large fleet.
