It's good, but can you change her name it's Tatsunomiya, the kanji can be read as both Ryuugu and Tatsunomiya. In the manga, Tatsunomiya is written in furigana (above the kanji).
Thanks for the correction, I just notice that her name pronounce as Tatsunomiya. I saw the kanji and translated it directly. I will address it in the next chapter.
