Recca unlocking Madoka by saving Neon, despite admitting that she was an annoying bitch. Neon understandably was baffled at the show of pity, but then Recca just said that there will be some people missing her genuinely if she died. Cue Miki and Aki hugging her tearfully, and forcing even a bitch like Neon (for that time, anyway) to tell them to stop crying while being tearful herself.
In the SODOM Arc, Kurei appears and kills Kadotsu. He then proceeds to try and grill Saicho, who had come to help Recca, to death, but is stopped by Joker. As they leave, Joker grins at Saicho, who understands that it's for nearly killing him back during the Ura Butou Satsujin.
When Aoi's madogu breaks, the Hokage call out to Yanagi, telling her how precious she is to them, and to come back to their senses. [[spoiler: It works, but quickly turns into a Hope Spot as Tendou Jigoku reveals that they were too late, and Yanagi dies. Crowning Moment of Heartbreaking, anybody?
At the end of Tendou Jigoku arc, Recca finally gets to call Kurei "brother" and they part way on peaceful terms just before Kurei returns to the past forever.
The losses of the Hokage during the Ura Butou Satsujin arc is filled with these:
Tokiya technically lost against Kai, but he's just that near in spiraling down the Despair Event Horizon once Kai told him about his sister's murderer and Driven to Suicide. He's not even in the mood to snark at Fuuko and Domon like usual. Then Yanagi came up and healed his wounds and gave him quite a grateful talk about how he survived. This healed his soul and enabled Tokiya to smile again... and either snark or get into a comical fight with Domon once again.
After losing against Mikoto via cheat, Fuuko completely went bonkers and emotionlessly beating Mikoto like a true savage. After Domon stopped such beatdown, Fuuko broke down crying stating that she couldn't fulfill the promise she made to a son of one of the fighters that Mikoto killed in the past about beating her in his father's revenge. Said boy stood up regardless, said that he's grateful for Fuuko giving her all and considers her the true winner, followed with the whole audience cheering for Fuuko, finally restoring her spunk and allowing her to smile again, the boy's little brother woke up just in time and remarked that Fuuko seriously looked like an angel that time.
