Ilya had stayed in Shadow City for two days but ultimately had to return to her world. Believe it or not, Miss Tohsaka was now looking after this young girl. She had arranged a school for Ilya in Britain and they were going to live together. Ilya was staying put because she was waiting for a new body, which was why she hadn't left with Tohsaka until now. Now, she needed to return to attend school.
It was evident that the little girl had quite a grudge about having to attend elementary school obediently.
Anyway, I was certainly taken aback when I heard the news. Tohsaka Rin? The penny-pinching miss who would buy almost-expired instant noodles, who would scrape off the gold plating from her dad's old mirrors to sell it and replace it with copper, who would note down even a single borrowed dollar in her memo—she was taking care of Ilya and arranging her education and living situation?
Had that girl recently thrown herself into the Somali business or something?
