** Kamijou asks her, “When summer ends, would you like to transfer into our school?”
** Index replies, “I want to create more memories between us.”
** Kamijou promises her, “We definitely will create many more memories.”
* In episode 6, when Touma [[spoiler:pretends his memory loss was a joke because he doesn't want to see Index cry]]. He has no idea who this girl is, doesn't know ''anything whatsoever'', but he's still [[TheHero Touma]].
** Also a TearJerker. "Touma... don't you remember? Index... Index... loved you, Touma..."
* After Aureolus Izzard has been defeated, Touma says that despite his murderous agenda, he still had enough decency and humanity not to use his RealityWarper powers to force Index to love him.
** [[spoiler: Stiyl giving Izzard a new face and identity, so the now powerless and amnesiac alchemist won't be hunted down and killed by the Roman Catholic Church.]]
* Misaka 10032 questions why Touma is trying to save her, since she's just a clone and there are roughly 9000 more for her. Touma answers that, [[ClonesArePeopleToo even if she's a clone, she's the only Misaka 10032 in the world. She is unique and can never be replaced]].
** When her cat licks her, causing her to [[WhenSheSmiles smile]].

* Out of all the people trying to capture, rescue, or kill Orsola Aquinas for her supposed knowledge of The Book Of Law, Touma was the only person who wanted to help ''her'' and didn't care about the knowledge. It certainly charmed her.
* A small moment at the beginning of episode 14 from season 2, [[http://toarumajutsunoindex.wikia.com/wiki/File:Toaru_Majutsu_no_Index_II_E14_00m_29s.jpg the look upon Mikoto's face]] when Touma is forced to dance around the bonfire with her. That is, [[MoodWhiplash until Kuroko dropkicks Touma in the back of the head]].
** The [[Manga/ACertainScientificRailgun Railgun]] manga expands on this scene, with Ruiko and Kazari quickly picking up on Mikoto's attraction to Touma. Ruiko asks Touma to dance with her around the bonfire as a way for him to return the favor of borrowing her protective charm, then feigns injury and asks Mikoto to dance with him instead. Kazari, meanwhile, tries to keep Kuroko from intervening for as long as possible.
* The final episode of season 2. [[spoiler: Last Order wakes up in the hospital and asks "Where is he [Accelerator]?" After the frog-faced doctor's reply of he'll be back soon, she nods and says "Okay, Misaka wants to see him soon," before going back to sleep. An incredibly cute end to an action filled season.]]
* Volume 15: Yomikawa talking [[AxCrazy Accelerator]] out of [[spoiler: killing Kakine, saying that no matter how dark and cold his world is, she will drag him out of it, because to her he isn't a monster, just a child that needs her help. Even Accelerator himself was stunned when she succeeded. Of course right then Kakine stabbed Yomikawa with his wings,]] which made Accelerator fly into UnstoppableRage coupled with DespairEventHorizon. And then Last Order appeared and stopped him with a CoolDownHug, just like that, because she knew he would never hurt her.

* Volume 22: [[spoiler: After 3 volumes of desperate searching for a way to save Last Order, Accelerator finally saves her using magic, and the first thing he does is embracing her tightly and saying "...Damn it, thank you... thank God...!!" Both of those are the last things one would expect Accelerator to do, but it just shows how important Last Order is for him, and it just makes you feel warm and fuzzy inside.]]
** [[spoiler: Shizuri Mugino calling Academy City out when she finds out that in the past they denied Shiage funds and basically forced him into the streets just because he was a Level 0 and assumed he was worthless. He may be a Level 0, but he was her greatest opponent, had earned her respect, and she's in love with him. Also, Shiage bringing Mugino back to sanity, forgiving her, and promising to help her reform ITEM.]]

-->'''Kumokawa Maria''':[[spoiler: I have no choice, so I’ll stay with you. Just like leaving flowers by a grave, this is nothing more than self-satisfaction, but what’s wrong with one person being led around by this awkward will? I will not stop you anymore. Just like in Baggage City, you will probably wear away every last piece of your body to achieve your goal, but I will watch over you as you do so. Once you see this selfishness through until you cannot move a finger, you truly lose your human form, and you face true death as nothing but a pile of flesh, then we can return to our city.]]
* NT 9:
** [[spoiler:After being put in a world where someone else is in his place]], Touma declares that almost everyone he knows hated him at first, but became his friends and allies. He has no doubt he could repair his bonds with everybody.
** It may have been cruel for [[spoiler:Othinus to put Touma in a world that doesn't need him, but it was rather nice to see everybody so kind and happy, even the '''Kiharas'''.]]
** [[spoiler:The Will of the Misaka Network stops Touma from committing suicide, then tells him this world isn't perfect, because '''he''' isn't in it. After convincing him it's okay to be selfish and fight for himself, it tells him it will be waiting for him in the original world.]]

** Touma chooses [[spoiler:to become the world's enemy if it means protecting one girl (Othinus). He even stops to think that he doesn't blame Index, Mikoto, and the others for not being able to understand his choice.]]
* NT 10:
** Touma remarks that if Othinus ends up arrested for her crimes:
-->He would have visited her countless times. No matter how much time it took and even if they had to wait until they were old and wrinkled, he would have made sure she was met with a smile when she finally was released from that cell. And once all of her crimes had been made up for, they could walk together in the light of the sun.
** Despite truly wanting to kill Othinus for endangering the world and threatening his loved ones in the process, [[spoiler:Accelerator throws his fight with Touma, reasoning that if he, the #1 Level 5, were defeated so soon, Academy City would hesitate to order others after them.]]

** In the past, Misaki was targeted by an esper-hating gang called Deadlock. Touma stepped in to help her. They tried to convince him to stand down by claiming Misaki used her mental powers to influence him into wanting to help her. It was of course not true, but Touma declared that it didn't matter; he will protect this girl from some punks who want to kill her just for being a Level 5, then kicked their asses.
** Even though [[spoiler:Touma automatically forgets about Misaki each time they meet due to brain damage, she still holds hope that they can have a relationship one day. When they meet at the end of the novel, he comments that her perfume smells familiar, which she says is a start. She thanks him for saving her and kisses him on the forehead, knowing he'll forget, and walks away saying, "I am a girl you once saved. Feel free to think of me like that☆"]]

* New Testament Volume 13:
** When the High Priest starts demolishing Mikoto's resolve by saying that she is a burden, Touma sticks up for her as not only being the one who had saved his life, but also acknowledging that she had given him the strength to keep fighting back even when the fight was meant to be completely hopeless.
