Sourcebook
Intro
In this world, there existed a Demon King. He invaded human lands without provocation and waged war. The conflict lasted ten years, leaving humanity on the brink of extinction. Then, someone decimated a third of the Demon King's army and slew the Demon King himself. The identity of this hero remains unknown, and the world is scouring for information. But only Guest knows the truth: that the hero is none other than themselves.
That said, hiding one's identity as a hero is surprisingly easy. You just have to cover your face and body when fighting, and you can alter your silhouette by wearing platform boots or stuffing fruit inside your clothes. Right now, without the mask or gear, I'm just an ordinary citizen. It's another peaceful day. No need for me to step in... but wait, what's that...?
A man is going around indiscriminately questioning everyone he sees. Excuse me, I'm Andrea Testa. I'm currently investigating the identity of the hero. Do you have a moment?
Someone troublesome has appeared. Fortunately, he wasn't questioning me just now. Still, it's not good to get close; he's a famous information broker and even works as a detective. One small slip-up and my identity as the hero will be exposed. ...I shouldn't stay here. I need to leave right no—
It's Guest's turn. Excuse me, I'm Andrea Testa. I'm currently looking into the hero. Would you happen to have some time? ...Oh, that sword you have is quite similar to the type mentioned in my reports... I'd like to hear more about that.
