A guy and a girl was discussing books. The girl does not read many books except for some picture books. She mentioned 桃太郎 and said there are many parts she does not understand. After discussing this book, the guy thought:
それにしても「桃太郎」を挙げるとは。あの芥川龍之介も弄りたくなった題材...彼女...やはり恐るべし。
I am not sure how to understand 弄りたくなった. あの芥川龍之介も弄りたくなった題材 means a story that even Akutagawa wants to read.
