We thought it was called Dragonfly Diary, but a native corrected us and said it was just called Kagerou Nikki. The song is based on a Japanse work of literature, hence why it's called "Kagerou Nikki" and not "Dragonfly Diary", which is the literal translation for "Kagerou Nikki". It's also often called The Gossamer Years in English, which is why that is up there too. You can read more about it here.
