TL Note 1: The title is a reference to the popular fan speculation/red herring of Nagito Komaedas name. If you rearrange the letters of his name, you get “Makoto Naegi da” which literally means “I am Makoto Naegi”.
TL Note 2: The pink words on the last page are also related to their names. “Naegi” means sapling, “eda” in Komaeda means branch.
And don’t forget, this is not canon material, and not spoiler content!
