Demon Hunting Manual: Beginning with Jack the Ripper

[On March 9th, I hunted a Devil's Flower and succeeded. I obtained some Pollen Pollen and my ability to identify plants improved.] [On April 16, I hunted a Blood Moon Werewolf. I succeeded. I got a good moonlight fur and recorded the skill "Crazy".] [On June 28th, I defeated the Quiet River Witch, failed, and gained a heart full of good feelings and unfinished thoughts] Huh? What do you mean? ··· My name is Ryan Herman, I live at 48 Charing Cross Street, and I run a small business of hunting monsters. It has been 20 years since I was reborn in this steam world dealing with demons and alchemy. My only colleague is this "Demon Hunting Manual" left behind. This guy can record demons and is a good partner left to me by my father. But why did it leave me with a mess? And after I'm done with it, what do you call me the "Pope of Disaster," "The Butcher of Evernight Ridge," and "The Miracle Worker?" Don't get me wrong, I'm just an ordinary person who killed all the demons due to a momentary mistake and had to retire early, really.
