* Issei's parents getting along with Rias's father and brother, much to [[AmazinglyEmbarrassingParents their charign]].

* Volume 8: Introducing, the [[BunnyEarsLawyer Four Lords Of Hell Plus One Ultimate Queen]] [[{{Sentai}} Rangers]]. Issei's reaction is ''hilarious'' while Rias thinks ''this was all real''. One particular example stands out: Satan-Pink (Serafore) sees a mysterious object and everyone blasts at said object. ''[[ThereIsNoKillLikeOverkill Said evil spirit dies on the spot.]]''

* Story about style of Miyama Zero (A Crossover with LightNovel/TheAmbitionOfOdaNobuna): Upon performing the aformentioned style, Issei and the ORC have swapped places with Nobuna Oda and her retainers. As Kiba tries to explain the situation, Cao Cao decides to make a visit to the ORC.

* Episode 7 Issei giving Saji a ''very'' firm handshake after he enthusiastically shakes hands with Asia, threatening that if he makes any more moves, he'll cut off his nuts and feed them to him - at which point Saji retaliates, gaining the upper hand as they 'argue', with both ending in a stalemate. Rias notes "This is embarrassing", which Sona agrees with.

* Grayfia's entire InVinoVeritas moment when she's at the [[HotSpringsEpisode mixed hot springs with Issei. Seeing that stoic maid becoming TheTease in one fell swoop is pretty funny.]]

* Episode 1: Just in the first minute, we already have Issei waking up to see that Rias has joined him in his bed, naked. When she wakes up, she contemplates whether or not to indulge Issei with something sexy. Of course, Asia has to interrupt them to remind them of morning training. When she opens the door to see a nude Rias in bed with Issei, she decides to strip off her clothes as well, much to Issei's shock.

*** And before that, Issei has an EroticDream where Rias, Akeno, Asia, Koneko, and Xenovia are topless, and invite him to trope their breasts, complete with their accurate personalities.

** The entire argument between Rias and Akeno is a gutbuster by itself. Rias, offended by how Akeno is one-upping her simply by being told she can go on a date with Issei if she defeats Diodora's mooks, gets one back by telling her that Issei gets more intimate with her in bed. Akeno, on her part, says that Rias is just jealous of how she's getting a date with Issei before she does. Diodora's Rook calls both of them out and tells them to focus on battling instead of arguing over their object of affection, but Rias and Akeno both tell her to mind her own business and obliterate her with a combined shot of magic.

** During the promotion test, the practical portion is revealed to be a duel between two applicants. Issei, [[HeroicSelfDeprecation being Issei]], is worried about how well he'll do, and treats it like a life-or-death battle. Five seconds later, he lands one punch and sends the other guy through the wall. Both Akeno and Kiba were cracking up when they heard about it.

** Kiba is greatly annoyed by the fact that Xenovia declares that she'll just [[AttackAttackAttack power through everything and that Kiba should be the only technique type. Kiba's FirstPersonSmartass commentaries are hilarious.]]

* Volume 14: Poor Issei, he can't even sleep on his own bed anymore thanks to the girls sleeping on it. Xenovia ''kicks him out while asleep.''

* Xenovia and Irina competing over the right to sit on Issei's lap. Also, Ravel's disappointment of her status as a latecomer and Sister Griselda arrival adds to the humour.

--->''There's definitely something wrong with the Two Heavenly Dragons of this era.''

** However, when Issei wakes up, he learns there are still some remaining side effects. As a result, he's suffering from Dragon Deficiency: breasts now ''harm'' him. He can't say the word, looking at them results in his vision getting blurry (except for [[ACupAngst Koneko's]]), and he can't touch or even think about them without experiencing immense pain. [[ThisIsGonnaSuck And then the Oppai Dragon Song begins playing.]]

* At Issei's High Class Devil promotion ceremony, a famous opera singer comes out and starts singing the Oppai Dragon song. Everyone is confused at such a song being sung at a formal event while Rias's father is moved to tears by the performance.

*** The first video shows the Gremory family when Sirzechs went off for work as Rias begged him to stay. Venelana tried to comfort her little daughter but she insisted and cried. At the same time, Lord Gremory held the camera and commented to Rias. Judging from little Rias' cute reactio and how Sirzechs and his father spoiled her as a child, no wonder the Gremory males are like that (this includes Issei).

** Everyone quickly picking up on the idea of a room designed ''only'' for sex being handed over to ''Issei'' and deciding that it is potentially one of the most dangerous and terrible things they've ever seen. Then they all start thinking about using it for themselves.

---> '''Issei''': Don't [[PrecisionFStrike fuck]] with me! (BOOST!) Rias' boobs are perfect and I won't let you reduce them!\\

* In Episode 8, after Azazel reveals his identity to Issei, [[SkeweredPriorities the latter is more pissed that because of the former, he was unable to suck Rias's breasts, as opposed to getting killed a season and a half ago]].

* Volume 7, Ddraig and Albion ''crying'' at the fact that Ddraig is now referred to as the Breast Dragon and Albion being the Butt Dragon.
* Volume 7 has Issei trying to talk to [[HearingVoices Akeno's breasts]] instead accidentally summons ''the freaking god of breasts!'' He then asks Taninim as to whether a breast god exists. '''Everyone''' stops fighting and looks at Issei like he's going crazy. The kicker as well was Ddraig backed him up and everyone thinks Ddraig lost it.
