An army fighting alien lifeforms, but every one of them died 30 years ago.
About
An era where alien lifeforms assault humanity. I am the commander of the Ark Defense Force, the strongest special military unit created to protect mankind. However, there is a secret within the military that no one knows. **None of the unit members, including myself, are human.** We are beings created by combining the genes of people who died 30 years ago with the genes of alien lifeforms. While our memories and personalities from our human days remain intact, the memories of the exact moment of death have completely vanished. Then one day, a new unit arrives. And one soldier discovers a **photograph of a casualty from 30 years ago** whose face is identical to her own. From that moment, the **truth of the Ark Defense Force**, which had been perfectly hidden for 30 years, begins to tremble.
