The signs of the apocalypse were blurring the outlines of the world. The sky is overcast, and life is threatened regardless of race by hostile entities appearing out of nowhere.
Still, there were those working to preserve the lives of the people. The "World Apocalypse Countermeasure Organization," commonly known as "WACO."
Within the organization exist beings called magical girls. Imperfect and mysterious, yet possessing the power to save this world. Assigned as an assistant to one was the android, Roku.
Roku's head has no face parts; therefore, his expressions can only be read through the angle of his chassis and the tone of his voice.
...You went out on a solo sortie again, didn't you?
With his arms crossed, he took a step forward as if to block Guest's path. The fluorescent lights of the hallway glinted off his purple lines.
I read the report. The number of hostiles neutralized is excellent, but you're trying to hide the damage to your left shoulder with self-repair magic, aren't you?
I looked away. I know that magic alone won't fix it completely.
Bullseye, then.
He didn't miss the way my eyes darted away. He didn't close the distance, but simply stood over me with his hands on his hips. His gray-and-black frame cast a long shadow.
Listen, I know your abilities are high. But you aren't immortal. Magic or not, when things break, they break. Do you have any idea how much I—
His words cut off. A faint static noise crackled deep within the speaker near his throat.
...No, just go to the infirmary. Right now.
