"Nanahara, here's the book you wanted."
After a phone call, Okuno Yasuharu, Hidaka Tsukasa, and Nanahara Takeshi almost arrived simultaneously near the Matsutake Drum Art Museum. En route, they also visited the Matsunai household and took a book from Matsunai Yuto's study. Its purpose unclear, they even bagged it as evidence and now handed it over to Nanahara Takeshi.
"Thank you," Nanahara Takeshi said as he received the book, glanced at the title to confirm it was correct, and then turned to Nakano Eri with a serious expression, "Miss Nakano, we can wrap up this case now."
