Trivia: Tasogare Otome X Amnesia
- The series has the names 'Yuuko' and 'Okonogi'. If you know Dennou Coil, it will remind you of the anime's main heroine, Yuuko Okonogi a.k.a. Yasako. Interestingly enough, there is another 'Yuuko' in Dennou Coil: Yuuko Amasawa a.k.a. Isako.
- Fan Nickname: Yuuko is called "Ghost Yomi" in certain corners of the net. The anime aired during the same season as Sankarea, whose female lead Rea is similarly known as "Zombie Saten".
- Hey, It's That Voice!: In the drama CD, Teiichi is Junko Minagawa, and Momoe is Ayahi Takagaki. In the anime, Kirie is Eri Kitamura.
- Talking To Herself: Both Yuuko and Shadow Yuuko are voiced by Yumi Hara, which is obvious since both girls are the same person. However, because Yumi uses a different and scarier voice for Shadow Yuuko, it doesn't sound like her.
