 * During the scene where Konori Mii accesses the databanks, not only are esper powers listed, but as well as magic terms such as the kanji translation for Innocentius, King of Witch Hunting, as well as that for Deep Blood. Furthermore, after Mii discovers the 99 match, Harumi is designated as a telepath, despite never undergoing the Power Curriculum Program. Another error is the word Pyrokinesis being separated into "Pyrokin" and "esis" rows.

Quotes

 * Ruiko: "It's not much of an ability compared to Shirai-san or Misaka-san... And from others people's perspective, it must be pretty lame... But I've become an esper!"
 * Ruiko: "Am I going to collapse too? Will I ever be able to wake up again? I didn't like being so powerless. But I couldn't give up on my hopes... Mama..."―Kazari.
 * Ruiko: "Are Level 0's defective, I wonder... And because a zero like me tried to obtain power by cheating, is this my punishment? I used something dangerous and dragged people around me into it..."―Kazari.
 * Kazari: "It's alright! If you go to sleep, I'll come wake you up right away! Saten-san and Akemi-san and everyone else who's sleeping! So just leave it all to me! And then I bet you'll be like, "gimme 5 more minutes!"... You're not defective! Even if you don't have any powers, you're always there to help me! Whether you have powers or not, you are you! Because, you're my friend!! So... So... Please don't say... such sad things..."―Ruiko.
 * Ruiko: "Thank you, Uiharu. Sorry for always causing you trouble. I'll leave the rest to you."―Kazari.
 * Mikoto: "She probably had a lot she wanted to talk about. Even so, I... even with my Level 5 powers... I couldn't do anything for her at all... For me, whenever I've run into hurdles in life, I've always stopped at nothing to overcome them. My Level 5 rank is a result of that. I've never really thought of it as anything special. But... I guess there are people who can't overcome those hurdles... I've never really thought of that possibility. "Your Level doesn't really mean anything, right?"... That was so insensitive of me..."―Kuroko regarding Ruiko.
 * Harumi: "I have no interest in other's powers. My goal is far greater."―Kazari.
 * Mikoto: "Of course. You're my junior, after all. At times like this, rely on your Onee-sama."―Kuroko.
