I need more chapters, so far it is so well done. I love the classic perks of isekai, but this also brought in some world building in jut two chapters without huge information dumps. It was efficient and works well in foreshadowing subtle relationship developments. I'm hope the Saint Shiraishi and our Sei-chan can become allies and friends because I can see the obnoxious Prince causing trouble. There are some pretty distinct characters; I see the Siant Shiraishi is falling into Mary Sue right now, but I already have hope she will develop tone more cunning or considerate without being oblivious.
