* The beginning battle scene, both for the characters involved and the animators.
* When a building collapses because of an earthquake, Maou manages to place magical barriers around every single person in the restaurant at once. Considering magic power for demons comes from fear, the logical explanation is that he ''used the fear the people in the restaurant felt to protect them''.
* Lucifer/Olba vs Alsiel/Emi. The explosions literally cover the entire sky. Lucifer {{BeamSpam}}ming, Emi calls her holy weapon, Olba shoots off thunder bolts, and Alsiel hurls cars like baseballs.
** You'll notice that Maou was not in the above line-up. This is because after he finishes stopping time, gently putting down the entire highway bridge and protecting the civilians, he ends the fight almost instantly. He crushes Olba with a glare (that somehow sends the priest ''through the wall''), and {{FlashStep}}s right in front of Lucifer's face. Maou then creates a chain of magic circles ''miles long'' to deliver a MegaTonPunch that could be seen from space.
** Lucifer's face when Maou teleports into his face is priceless. He practically wets himself.
* Chiho is not afraid to unleash the F***ing Fury on Maou if he should bring up any talk about whether she wants her memory of him erased for her own good... or if he doesn't take handmade double decker lunchboxes from other girls seriously. Demon lord and ability to level city blocks by will be damned, she will launch across the table, bodily drag you to her end and shake you silly till you answer her properly.
* Let's not ignore the extent of Maou's, Alciel's and Emi's achievements concerning their dedicated and sincere efforts in the mundane world and their work life.
* In episode 12, just when it seems that Lucifer is going to become TheStarscream again by conspiring with Olba, he reveals that he has [[OutGambitted tricked Olba]] into calling the Moon down to Earth ostensibly for the benefit of Archangel Sariel where in fact the fear and panic generated by that phenomenon provides Maou with much more power instead. He then knocks out Olba and declares that "[[HeartwarmingMoments Heaven is a place on Earth, in a six tatami-size apartment]]". Then adds that "[[FunnyMoments Being a]] [[{{NEET}} bum]] [[FunnyMoments is the best]]".
** Following that was a sequence that put Episode 5 to shame, where Maou wrecked Sariel.
** And then Sariel tries to take Chi as hostage. SHE UPPERCUTS AND KICKS HIM INTO THE NEXT BUILDING. [[spoiler:Actually, Maou used a disguise to trick Sariel. The lesson here: Don't [[TryingToCatchMeFightingDirty try to use underhanded methods in a fight]] with an EvilOverlord as opponent. You will lose!]]
** Right after Maou gets his power back, it takes the form of a tornado of energy.
