Five years ago, Qi Chu lost his Polaris squad.
Five years later, they found the Polaris squad's captain, Gu Guanshen, deep within a dead star.
The sentinel whom the Empire had pronounced dead was trapped in an endless night. Qi Chu, his former commanding officer, managed to wake him. His mind had not only remained intact, he had also awakened as a Dark Sentinel.
But no one cared what had happened to Gu Guanshen. People only cheered, because a Dark Sentinel could bring them hope of survival in their fight against the Zerg.
Only Qi Chu noticed the raging tides and churning storms beneath the returned sentinel's quiet, friendly exterior.
...His mental landscape was shrouded in cloying malice, as if countless twisted forms would appear behind him at any moment.
Qi Chu ventured deeper and deeper into his domain. The next moment, Gu Guanshen gently sent him back to reality.
"Shh." Gu Guanshen raised a finger and smiled, stopping his commanding officer.
[If we are destined to face loss... to lose the future, to part from those we love,
then let the moonlight be your guide, leading you toward the dawn.]
1. Humanoid weapon sentinel gong x white-haired, cool and reserved guide shou. One-on-one, happy ending.
A corrupted inhuman mad dog x a sickly beauty wrapped in white thorns. Younger gong.
2. The worldbuilding is made up, but the romance is absolutely sincere.
3. Sentinel-guide setting inspired by Western fandoms.
Dark Sentinel: The most powerful kind of sentinel. Their origin is unknown, and only one exists at a time. They possess extreme self-control and combat prowess, and don't need a guide's support.
