The Aethelgard Chronicles" plunges readers into a world where humanity clings to survival within colossal, fortified castle-cities, constantly threatened by a relentless alien menace known as the Xylos Swarm. At the heart of humanity's defense is the elite Hunter Corps, operated by the powerful organization ACE (Alien Containment & Eradication).

Follow the journey of Kai, a brilliant but impulsive hunter, and Ren, a fiercely loyal and overconfident brawler, as they navigate a partnership fraught with bickering and unspoken tension. Initially bound by duty, their relationship deepens amidst high-stakes missions and unsettling discoveries that challenge everything they thought they knew about their world and the very nature of the alien threat.

As a shadowy conspiracy within the ranks of their protectors begins to unravel, Kai and Ren find themselves caught between a collapsing city and a truth more terrifying than any alien. Their bond, forged in the fires of conflict and tested by unexpected vulnerability, becomes their greatest weapon against forces that seek to control not just their world, but their very minds. This is a tale of survival, unlikely alliances, and the quiet, awkward blossoming of affection amidst overwhelming chaos.

Honestly I'm just writing that comes to my mind (Ignore some parts if they are not weaving together, this not an official draft)
