The very first chapter Lelouch sees parallels in young!Matsumoto's behavior with Nunnally, and his Big Brother Instinct naturally kicks in, such as letting her sleep with him after having a nightmare.
Chapter 13 has Lelouch say to Soifon with regards to their friendship "While I may not always be worthy of your friendship, I shall always value it."
Chapter 14 when canon changes dramatically by having Soifon decide to go with Yoruichi. Soifon brings up Yoruichi's promise to her and gets a pat on the head.
The end of chapter 16. Yuna tells Lelouch to come back to 10th Division with her saying that it's his home.
Most of chapter 18 where the Lelouch/Yuna shipping is concerned. More specifically the dancing between them and Yuna laying her head on Lelouch's shoulder afterwards only for the chapter to end with them kissing each other.
Byakuya's proposal to Hisana (some fans have actually said the chapter feels like a case of saccharine)]]
Chapter 24 during the All Just a Dream segment, Lelouch is unsurprised that no one has come to see him in recovery. Later, when he wakes up for real Hisana, Byakuya, Rangiku, Shisato, Naomi, Nemu, Vera, Ryou, Isshin, Kendra, Stefan and Kukaku are all at his bedside and at the end of the chapter Lelouch realizes he actually has friends he can trust.
At the end of chapter 28 seeing Lelouch being so nice to Vera due to her PTSD, missing hand, and missing eye and comforting her skittishness and telling her how good he's been to her going out of his way to give her a family.
Chapter 30, Lelouch pulling Momo out of her Heroic BSoD after he and the phantoms murder the Atrumier family.
Hisana and Rukia finally managing to come to terms with each other.
The baby is my future. Susanna had just told Lelouch she doesn't want the baby to ruin his future ambitions and wants and the above is his response. Too bad this went straight to Harsher in Hindsight due to three simple words, "The fetus died."
After Hisana defeats Zommari the sisterly moment she shares with Rukia is so fluffy and sweet
Lelouch and Nemu getting back together in chapter 69 is definitely this That entire scene even after Ichigo rescues Orihime from Needles and his goons is so fluffy and sweet.
Chapter 74:
The wedding when Rukia and Kaien are giving their vows.
Later the same chapter the romantic interaction between Ichigo and Orihime is so touching with Ichigo asking permission to fondle Orihime. It seems Chivalry isn't dead after all.
Yumichika’s interactions with Shisato after Ikkaku’s death definitely qualify as well.
When Hisana kisses Byakuya's cheek and tells him that she's pregnant and follows up with "Happy Birthday Byakuya-sama".
Everything involving Ichigo and his nakama from his dad telling him that he’s just going to be his dad from now on he lost his powers AGAIN, to Kukaku saying there’s always an extra bedroom at the Shiba manor to Ichigo saying to Lelouch he knows who to call on if he needs assistance.
When Ashido, Nemu, Byakuya, Kukaku, Yosei, and Susanna all pile into the archives to finish Lelouch's plot to Take down the Central Forty Six while he's asleep in the corner. It really shows how close knit of a bond Lelouch has with his allies.
Everything involving the Kuchiki family in chapter 104 from Ichigo finding out that Kyo and Isao are unhurt to Hisana tearfully asking Byakuya why he didn't ask for her help, in what will make readers reminiscent of Soifon's tearful inquiry to Yoruichi.
Ichigo telling Orihime that she’s his girl.
Ichigo breaking free from his seal and the first thing that happens is his reunion with Orihime.
Byakuya revealing in the Aizen’s Revenge arc that he’s alive and well and explaining that he thought he would have to defend the lesser nobles from Aizen’s group, but they all banded together and helped him to live.
The Reveal that the woman in crimson armor, claiming to be Rita’s herald, is the spirit of Mari Akari. The following scene doubles as a Tear Jerker as well. The fact that Ichigo is crying, though he denies it, should be an indication as to the effect the scene is meant to have on the reader. Continuing from that same thread, her reunion with Yuna the very next chapter is equally heartwarming.
Rita telling Unohana that she’s very proud of her and always has been.
The ending of the Aizen's Revenge arc with Lelouch and Susanna standing up on the hill after Lelouch's resolve was shaken a little by Aizen, but Susanna tells him that Lelouch has made great strides.
Any moment between Rita and Unohana in chapter 133. More than one fan has said the chapter should be renamed Unohana and Rita's Mother/Daughter Bonding Time. Some scenes do borderline Tear Jerker as well.
Susanna explaining why she loves Lelouch so much, unless you're not a SusaLu fan. Earlier in that same chapter, Kendra sticks her neck out for Lelouch saying that she believes that it’s best the Soul Society not persecute Lelouch for the SAZ massacre since they can’t arrest him Ex-post facto and also because he is sharing it with them to show that he’s not trying to hide it. She says that he basically needs their sympathy and she’s willing to give it. Considering Kendra was trying to arrest Lelouch some twenty or so years ago for being a vigilante this says a lot. Ichigo seems to have really had an effect on her.
Nonette showing up to help Cornelia during the Black Rebellion and leaving an uplifting voicemail to keep her from reaching Despair Event Horizon. Nonette really is Cornelia’s best friend.
The moment with Lelouch and Susanna in 167. First time Susanna's ever given him a Get A Hold Of Yourself Man type of speech.
Lelouch finding out that he is responsible for saving Nunnally from the FLEIJA detonation and the scene that follows.
Ichigo and Orihime reunited after nine years of his disappearance.
Chapter 178: Lelouch and Cornelia's reunion. And a bonus scene from an alternate universe, where Lelouch called Cornelia after the Invasion of Japan.
Chapter 180:
Cornelia gets to see Euphemia again in the Soul Society. She also gets to see Nonette too.
There's also Lelouch getting to see Nunnally again and that one had the author in tears writing it.
Suzaku's reunion with Euphie and Keigo's reunion with Riruka.
Kasumi putting her trust in a single person: Ichigo. On top of Ichigo saying to her that she’s been his friend since she helped rescue his sister. And her falling asleep, using him as a pillow. As she herself notes, it's the first time she's never had to keep one eye open.
From being deader than a doornail to suddenly being alive and well, considering Lelouch shows up at his own funeral, dressed as Zero, it really breaks the miserable tone and sets it to both a heartwarming one and an awesome one. And then later that same chapter, years into the future he becomes is a daddy.
The Stinger; Rita's loyalty has always been to Feluca, not Soul King, and putting Feluca in charge, and with it the promise of a better world, must count.
