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.
Base Breaker: Between Luke and Cecily. Although an insensitive Jerkass with something of a heart of gold later on fans (particularly Western fans) support Luke over Cecily due to her violent Tsundere tendencies. This is not helped by the fact that the anime version (which many fans are more familiar with) portrays her as inept and weak compared to her original light novel and manga versions where she is far more competent and morally sound than Luke. However many fans of the anime nonetheless support Cecily for her more heroic traits alongside fans familiar with the manga and light novels.
The Scrappy: To some, Princess Charlotte and her entourage (at least in the anime). As a result of being Easily ForgivenKarma Houdinis for trying to kill Cecily and trying to kidnap both Aria and Luke, then behaving like entitled bastards by demanding that Cecily puts them up while they stay in the city.
Tear Jerker: During Siegfried's assault, Cecily, in desperation and terror, flat-out screams for Luke. But there is no Big Damn Heroes moment. Luke does not come to save her. Cecily is brutally beaten, mocked about her helplessness, and left naked and traumatized on the dirty floor of a barn. After Siegfried leaves, she's so sickened and shaken that she vomits. It's a horrific scene and utterly heart-wrenching.
