Hey, who says a show about mass killings canít have heartwarming moments?
----

* [[PetTheDog Light takes a break from his busy schedule to help Sayu with her homework.]]
** ...and doing her chores for her too! [[AffablyEvil Such a great brother]]!
* [[GratuitousJapanese Kawaii!]] Ryuk eats an apple right out of Lightís hand.
** Many of Light and Ryuk's interactions are oddly sweet- [[VillainsOutShopping like when watching wrestling matches or playing]] VideoGame/MarioKart together.
* Rem with Misa, all the time.
* During the Yotsuba arc:
-->'''L:''' [[HoYay Youíve been staring at me for the last five minutes.]] Let me guess, it's because Iím the only one eating cake, right? Here.
* Misa giving L a peck on the cheek.
** L's reaction is even more heartwarming. He begins to consider falling in love with Misa and she responds with just being good friends, he's just as happy.
*** Because he's lying there. Remember L is a huge liar. If he was lying about being friends with Light, he's lying about Misa too.
**** Him lying about being friends with Light is can be seen as debatable, and even if he was, it certainly doesn't mean he lies about how his feelings in every single situation. [[FalseDichotomy He doesn't have to be honest or lying 100% of the time.]]
* L washes Light's feet.
* In ''Relight 2'' L pays a secret visit to the Wammy Orphans.
* Everything about Light during the Yotsuba arc... [[spoiler: which makes his return to his evil self that much more heartbreaking]].
* Episode 11, when the entire police force shows up to help Soichiro out of Sakura TV safely. Also a CrowningMomentOfAwesome.
** In that light (no pun intended), the part where [[spoiler: Higuchi is caught]] is also pretty heartwarming, as by this time, all but six of the police had quit because they were afraid of Kira, one quit because he was suspicious of L, [[spoiler: one was killed]], and [[spoiler: one quit because he was not happy with L testing his resolve to stay]]. Light appears surprised at the police's cooperation, and then he and L jointly realize that [[spoiler: the police were led in this action by the two who most recently quit, who subsequently return to the task force.]]
** Perhaps this a strange moment to like, but there was something oddly heartwarming about one part of 'Ridicule', which takes place at Christmas. The task force are still slaving away to catch Kira, Misa's getting drunk and depressed, [[spoiler: the 'three Kiras']] are committing more acts of mass murder, and there's very little goodwill anywhere. But at the same time, Near is celebrating the holiday the way it's supposed to celebrated - playing with his toys (admittedly, he does that anyway) and hanging baubles on a Christmas tree.
* "I feel you are the first friend I've ever had." L calls Light his friend, reaching out to another human being for what's probably the first time in his life. For a while it even seems like Light is reconsidering trying to kill L, then quickly becomes a {{Tearjerker}} when we see that he still wants to.
** Although, considering that L was also lying when he told Light that...
** WordofGod is that L was lying in the manga/anime, but in L:Change the World, it is revealed [[spoiler: that in that universe, L did truly think of Light as a friend and is seen mourning him, since L outlives Light in this AlternateContinuity.]]
** Also episode 26 of the anime is similarly both heartwarming and tearjerker-worthy [[spoiler: Light ''[[AntagonistInMourning misses]]'' Ryuuzaki. He's ''lonely'' without him around.]]
*** Light wobbles a little there, but quickly puts himself back on track. It's clearer in the manga. And it's part of the tragedy - he and L could, perhaps, be friends; it's just that nothing like that could ever compare to [[UtopiaJustifiesTheMeans Light's crusade]]. Not to mention [[WorthyOpponent his abiding need to beat L right into the grave]].
*** It's both heartwarming and sad because it shows that in any other world, in ''any other scenario'', they could have been the best of friends. Alas, it was '''not''' meant to be.
*** It's worth mentioning that his missing Ryuuzaki is probably a little bit of VictoryIsBoring coming into play too. Ryuuzaki was the only one who had truly challenged him on an intellectual level. Part of Light was probably missing the game.
* In episode 25 of the anime, Misa in her Gothic Lolita outfit, walking and singing that song.
** Misa's trust in Light in general is really very touching.
* Unrelated to Light and L, but... in chapter OneHundredAndEight, Near not only is calling all the survivors up again to keep working together, but if you look closely, there's that one shot of him playing as usual... [[spoiler: and he's eating a bar of chocolate, just like Mello used to [[note]]Okay, you find a way to phrase that which doesn't make it clear that Mello dies[[/note]].]]
* Lil' Mikami. "Thank you, Teru!" D'awww.
* In ''L: Change the [=WorLd=]'', "You're a good girl. I believed in you", and "Maki, welcome home. Make tomorrow a good day too."
* Late in the series, Soichiro tells his wife that he'll let her divorce him due to the trouble his involvement in the Kira case has brought the Yagami family. She is shocked and refuses, saying that she'll always stand by him, no matter how bad things get. He slumps in relief and thanks her. Seriously, who wouldn't want a love interest that was ''that'' devoted?
* The task force going out to look for Light [[spoiler:after he flees the Yellow Box Warehouse]], especially since they defy Near to do it.
* The conversation between Light and L on the roof and the subsequent [[BigLippedAlligatorMoment slightly awkward foot-massage scene]] are oddly [[TearJerker/DeathNote sad]] and heartwarming simply because out of context, it seems like L an d Light should be best friends - [[spoiler: too bad Light's about to kill L.]]
* The scene where [[spoiler:Near asks Rester to escort him to Japan, because he's never boarded a plane alone before]]
* The scene in the Yotsuba arc where Misa sits in Light's lap is really sweet.
* The final conversation between L and Soichiro Yagami in the Last Name. L told Soichiro that the latter is a good father to him.
* Aizawa's moment with his wife and daughter in the park after [[spoiler:he quits the task force]].
* During the first movie, when they put cameras in Light's house L, in his usual position is half asleep. The first thing Souichiro does when seeing him is put a blanket on his shoulders. It shows that despite their views on fighting crime, he treats him no different than he would treat his own son.
