Quotes

 * Judgment members: "This is Judgment!"―to STUDY.
 * Kuroko: "Come one, come all! Through these gates, I, Onee-sama's herald, Shirai Kuroko, shall not let you set one foot!"
 * Mitsuko: "Do you think I'll let you lay a finger on my friends? You're a hundred years too early!"
 * Kuroko: "I'm not the same Kuroko you're used to seeing. Because... I'm fighting... alongside Onee-sama!"
 * Mikoto: "If I were alone, maybe it'd be rough. But... I'm not alone anymore. Everyone's... fighting alongside me!"―to Haruki.
 * Mitsuko: "Allow me to introduce you to the general-purpose transforming robot, built by Kongou Airlines' Second Academy City Factory using all of our technical expertise!... Introducing... Ekaterina II S!"

 * Haruki: "Spend your final moments c-cowering in fear!"―to Mikoto.
 * Mikoto: "Dying and avoiding responsibility? You're not getting off that easy. I know someone who was already too strong, and still tried to become stronger. I know people who despise not having any powers, just like you, who did inhuman things, trying to get them. I know people who thought that they were just puppets, and silently accepted a cruel fate. And I know a complete idiot who thought that they could just die, if that's what it took to protect them. But who's stronger or who's weaker, who comes out on top or on bottom... None of that matters. I promised everyone. To save Febri, no matter what. To protect this city. And if it's what it takes, I'll save you too!"―Mikoto's speech to Aritomi Haruki.

 * Ruiko: "I see. So basically, the power of love?"―to Shinobu upon hearing her explanation on how to wake Janie.
 * Misaka 19090: "Thank you for giving me a heart."―to Shinobu.
