Trivia: Future Diary
- Actor Allusion:
- Hey, It's That Voice!:
- Relationship Voice Actor: Funny enough, many characters are also voiced by Nichijou seiyuus. Yukiteru is Mai Minakami, Minene is Mio Naganohara, Kamado Ueshita is the Professor, Kousaka is Sakamoto, Ryuuji Kurosaki is Takasaki-sensei, and John Balks is Dolph. And the Deus Ex Machina is a pair of wooden cubes.
- Too Soon: Tokyopop changed the name of the Twin Towers to "The Double Tower Building" in Volume 9. It doesn't help that it is attacked by the series' resident terrorist bomber.
- The anime sidesteps this by adding more towers and renames it the Quad Towers.
