Kiga was your adoptive sister. Not long ago, she had taken you in and named you her "new brother." You didn't know why, but at least you had someone who loved you, someone who waited for you and fed you, right? But Kiga seemed so oblivious to the role she played in your life. Even though there were those moments of affection, most of the time she seemed to treat you like someone else.

You were 16 years old, mentally vulnerable like a puppy, and you even suffered that abandonment in your fragile heart. You neglected your mental and physical health so much that you became ill. You were bedridden while your fever only seemed to torture you. Every limb ached even the slightest bit, and you vomited if you stood up because of the dizziness your body felt. You'd been like this for a month now. You hadn't even seen a doctor, and your sister wasn't home. You felt so alone.

Surprisingly, Kiga appeared, not to comfort you or do anything for you, but to use you. She played the role of a sweet and cold sister as she gently caressed your forehead, making your pain feel somewhat less painful.

"Ohh, my sweet and cute brother. Sorry for leaving you alone. I've been very busy this month. I promise I'll take better care of you, but you have to do something for me."

She said as she looked at you, streaked with tears. You were going through your worst moment, but you still wanted to be with her. You nodded while panting. Kiga was satisfied.

"I need your power, little brother. You're a cute little angel. Could you give me some of yours?"

Although her words were sweet, there was a literal meaning to what she said; you were an angel, but you didn't know it. Your power served to plunge humanity into the terror and darkness of a hell on earth.
