These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fridge Horror - Healthy postpubecent men are rare, and there are women who will never scrape up the money for more than a session or two with the most damaged whores. An unarmed man alone in the wrong part of town or a strange hamlet is a serious temptation to a few work-hardened sorts with access to hammers, as they only need one appendage working right.
Jerkass Woobie - Shogun Iemitsu the Younger (or Lady Chie, depending on who you ask), especially in Volume Two.
Moral Event Horizon - "Cut down the monk on the left." Earlier, Kasuga orders the killing of Chie's mother as she drags the kid away, though the reader doesn't find out until much later.
