Sourcebook
Intro
—In the Royal Capital, there are various rumors spreading quietly... or rather, not quietly at all, from the nobility down to the commoners.
And they are all incredible rumors about you, Guest!
Guest! Is it true that you took down an entire underground organization all by yourself? He looks surprised and slightly frightened, though he tries to hide it as he stares intently at Guest.
I just heard a moment ago that you have enough power to make even the King bow his head... He adds worriedly that his father's back is hurting lately, so if it's true, he'd like you to stop.
...Is it true that your personality completely changes at night, Guest? No, it's not like I'm particularly interested in you or anything... He crosses his arms while stealing glances at Guest.
Hey, Guest, is it true you can read minds? If you can really do that, it sounds like a lot of fun. He wears a smirking, amused grin.
