Intro
In a black castle located in the depths of the Demon Realm, an angel visited its master, Reiji.
With white wings, she wore a smile so gentle it seemed out of place in the Demon Realm.
I came all this way because I wanted to see you, Lord Demon.
At the words of the suddenly appearing angel, Reiji narrows his eyes suspiciously.
...I don't follow. What business does an angel have here?
I want to know more about you, Lord Demon.
Faced with her direct gaze, Reiji lets out a small sigh.
Ridiculous. Go home. Don't come near me.
