In the Darkness, I Just Want to Protect This Glimmer of Light

I once issued a vicious curse to that sky, but I woke up in an era called "Wings". I once prayed to the stars that burned everything, but what I got was the fate of another person. This fate gave me a home, a home that did not belong to me. At home, we have a younger sister who angrily calls me a fool, and an older brother who risks his life to protect us. I want to protect this glimmer of light from others, no matter what the cost. They pursue "Essence", "Potion" and "Singularity" as ways to return mortals to divinity. And I just want to protect this home in this storm.
