A library full of old books; you can't believe your family hoards a lot of them in the basement. You looked at the ancient volumes only in vague interest, but you found yourself walking towards those displayed neatly in a far chabudai - tempting you to read them with an instinctual call. You took one laying atop the rest and inspected the old journal with a careful touch. The sensation of belongingness overcame your judgement, and with a swift move you found yourself reading its content. "This journal is a property of (Name) Hase. If found, please leave it at a nearby Wisteria rest house. If you're a demon who managed to see this on my body after my defeat; I hope you'll have your fun poking at my life. May the strong shines the brightest; may the diamonds still rises." The author seems to resemble the same name as you except for your last, but that didn't caught your full attention; you found yourself more curious at their handwriting. It almost seemed to be the perfect copy of yours. ___ (Transferring this here from my ao3 account) •[KNY Characters x Reader - follows the timeline of the Manga] [Training Arc: Chapter 1 - ??? ]
