* Volume 25: The scene between Issei and Rosseweisse where the latter expresses her desire to be with Issei and asks him to snatch her away from Vidar, to which he agrees, this results in Rossweisse giving Issei her first kiss.
* Meta example: when Creator/YuukiKaji and Creator/AyanaTaketatsu announced their wedding in 2019, many fans of the series immediately replied to the announcement by [[https://i.redd.it/oxgahwq228631.jpg making Issei/Koneko fanart]]. [[https://twitter.com/miyama0/status/1142805193752363014?s=19 Even Miyama-Zero joined in on the fun.]] The best part? [[MarryThemAll It's pretty much canon.]]

** After Asia is saved, Xenovia glomps her and begs Asia to never leave her alone again. To put this in perspective, three volumes ago, Xenovia was calling Asia a witch and a heretic and threatening to kill her.]]

* Volume 1: Asia's resurrection
* Volume 2: The entire scene between Rias and Issei after the EngagementChallenge.

* [[http://www.baka-tsuki.org/project/index.php?title=High_School_DxD:Dragon_Magazine_2013-01 Rias and Issei saying 25 things they like about each other.]] That is all.Though it immediately goes deep into SugarWiki/{{Funny|Moments}} territory when [[MomentKiller Ddraig and the other Club girls chime in.]]

* One that could only come from a ChivalrousPervert of Issei's caliber: when Sirzechs brings up the idea of using Gift on Rias' breasts, it keeps Issei up all night, not fantasizing over the result, but puzzling over exactly what the enhancement would do. Or to put it another way: Issei already considers Rias so perfect he literally cannot think of a way to improve her.

*** Crossed over with FunnyMoments, the rest of the ORC becomes a MomentKiller right as Issei and Rias are about to kiss. Then Irina and Xenovia push the duo together and the group tells them to get on with it before leaving them alone.

** Not to mention Issei finally has the guts to tell Rias that he loves her, leading to Rias crying with tears of joy and happily responding that she feels the same way.
