Yes, a villain who hurts our MC will show up quite soon and you can probably guess everyone's response
Could papa demon be any more adorable? I just love the way he dote on Estelle. I just wish he didn’t always feel the need to hide important information from her about what sort of people threaten her. I feel like she’s so much more vulnerable because of that and it’s gonna cause more harm than good.
@MCX01 While I agree Estelle is likely loved by the spirits, I'm pretty sure the spirit stones aren't capable of independent thought or emotion. Rather, the spirit stones react to their holder's emotions. The Duke's stone is giving off such a fond reaction in this chapter because that is how he is feeling towards Estelle, and earlier in chapter 26 his stone reacted so severely because he was feeling hostile towards the wizards that Estelle had spotted. I'm only about 90% sure this is the case though, so I could be mistaken in this regard.
