Heartwarming / Black Butler

Jack the Ripper Arc

• Ciel giving Madame Red a tender kiss on the cheek. Ciel is known to never let anyone (save Sebastian) touch him. Shows just how much he loves his aunt Anne.
• Ciel laying a red dress over Angelina's body during her funeral. No matter what Grell may say or think, in Ciel's eyes red was truly the color that represented his aunt.
• It's a small thing, but once Grell reveals she identifies as female, none of the characters ever misgender her. For Victorian England, that's rather remarkable.

Indian Butler Arc

• Agni's backstory. The son of a corrupt brahmin, he spent his life indulging himself and casually breaking the law until it came down on him. As they prepared to hang him, Soma - for no reason other than his own whim - jumped onto the gallows platform and saved his life. Agni's Undying Loyalty suddenly makes a lot of sense.
  "And at that moment, God appeared."
• Agni showing the household staff how to safely do their jobs and them all happily working together to make dinner in chapter 17. Aww. Sebastian could really learn a thing or two from Agni when it comes to directing them.

Circus Arc

• In episode 3 of the Book of Circus, one of the Scottland Yard officers buys a bundle of flowers from a little girl because she reminds him of his daughter, Emily. Too bad the girl gets abducted by the Noah circus troupe minutes later and the policeman (and all his colleagues) get brutally murdered for trying to save the girl.
• Sebastian's genuine surprised happiness when fellow Battle Butler Agni reveals that he sees him as a friend.
• The very ending of Kuroshitsuji III: The spirits of Joker, Peter, Wendy, Jumbo, Dagger, Beast, and Doll entering what is presumably Heaven. All while Ciel and Sebastian of all people watch in near awe. Enough said.
  • Alternative interpretation is that those were merely hallucinations Ciel and Sebastian were having. While they still have quite the low opinion of the troupe and humanity in general going by their final pieces of dialogue (Ciel spitting on the troupe's whole plight in his Laughing Mad moment and Sebastian seeing them as creatures willing to trample on others), this makes it appear that even they believe in whatever capacity that the troupe, in death, are at peace.
  • The melody that plays during the scene is one of the softest and sweetest played throughout the whole series.
• Chapter 96.5 (That Butler, Friendly) is probably the most heart-warming thing in the manga. We get to see a little bit of the Circus members' history together when Freckles loses a tooth and, rather than letting Peter tell her that the tooth fairy isn't real, Joker and co. go out and earn a coin to give to Freckles when she wakes up. It gets even more heartwarming when Freckles uses that money to buy them all bread. They recount this story over dinner with Sebastian and Ciel on the two's first night at the circus, and it genuinely seems like the circus members have bonded with them. Becomes sad when you realize that all of these characters die brutally for a cause that was worthless in the end.
• After everyone involved in the kidnappings were slain, Ciel and Sebastian do make an attempt to find and save the orphans that the circus troupe were protecting. Granted, this was out of duty and certainly not out of wanting to help the troupe in any way, but it counts for something nonetheless. It's just a shame about what they find when they reach the orphanage...
• For those who want a touch of fluff or subscribe to the Animated Actor interpretation, this group picture of the duo and the troupe that was released shortly after the anime wrapped up.

Phantomhive Manor Murders Arc

• There's one chapter where the Phantomhive three are talking about how far they've come, and how much they owe Ciel and Sebastian. Doubles as a tearjerker, because none of them have any idea that Sebastian's a demon and they're just being manipulated, but it's still touching to see how they feel.
  • Father Jeremy's smile when Finny reads a play ticket, when we learn that he's actually Sebastian. Who taught Finny to read? Sebastian.
• Ciel taking in Snake, despite lying to him that he was looking for his friends when said friends had attempted to ambush Ciel's mansion and were killed by Ciel's staff. However in later chapters, it's shown that Ciel does geniunely care for Snake, such as the brief encouragement he gives to Snake when other people were mocking his appearance. Also, he told Snake to get on the rescue boats in his place.
• Ciel offering Sebastian a handkerchief so that he can wipe off the tears and snot the staff and Elizabeth cried on him when he "came back from the dead" is a cutely chummy moment, considering that Sebastian is the one that usually takes care of him.

Luxury Liner Arc

• Chapter 51: Ciel actually blushes when Lizzy hugs him and says she'll go anywhere with him. Awww. This may be the first time he's shown romantic feelings towards her.
• Ciel telling Snake to get onto one of the rescue boats instead of him, even citing that Snake's snake-friends can't survive in the cold water.
• Chapter 62 and 63 are a strange sort, mostly because it shows Ciel and Sebastian busting ass to get to where they are today. It's creepy and yet, it's rather sweet.
  • Ciel gives the demon the name "Sebastian", mentioning that it was the name of his dog. It just seems funny at first, a joke at the demon's expense... until one realizes that dogs are very often loyal and faithful companions.
  • Upon seeing Tanaka again, Ciel calls him "grandpa", then runs up to hug him. They're both so obviously relieved to see each other alive and safe.
• Sebastian's and Ciel's exchange at the end of chapter 65 of the manga. This is the first time we have seen Ciel being genuinely concerned about Sebastian and treating him with kindness. True, Sebastian is a demon, but the little scene at the end is very sweet nevertheless.
• In chapter 66, Ciel cheats during the egg hunt by pretending to have an asthma attack in order to distract Soma and Agni. Their reaction after losing because of his ploy? They are happy Ciel is well.
  • Ciel won just to make Elizabeth happy.

Public School Arc

• In chapter 70 MacMillan going into Ciel's bed to be next to him while they have their talk.
• After learning that Ciel has been aiming for the batter's face in Cricket the crowd starts booing about blue house's poor sportmanship. How does the P4 of the oppossing team, the power based green house, respond? Greenhill gives the crowd a reason you suck speech defending Ciel's actions on the basis that aiming for someone's face requires a lot of practice and the use such underhanded tactics is just proof that blue house really is serious about the tournament winning this year.

Emerald Witch Arc

• Chapter 85, which takes place between the Public School arc and the Emerald Witch arc, has Ciel and Sebastian taking the servants out to London for a day of shopping. It's quite sweet, from Finny's Squee at seeing the sights to Ciel grabbing Bard candy cigarettes to help with his smoking problem.
• Chapter 91, Finny's flashback and speech to Ciel.
  • The story about when Ciel gave Finny his name is really touching. Especially since having a name means so much to Finny: his name has given him a whole new identity and allowed him to become something more then a disposable test subject. "You taught me how to grow," indeed.
  • Finny's backstory in the anime as well. "I just want to go outside!" And now we know why Finny's a gardener.
  • When Sebastian needed to "talk" to Ciel, who was suffering some Heroic BSoD and was scared out of his mind by anyone except Finny, Finny jumped up and stood in front of the bed, refusing to let Sebastian by. Finny knows damn well how powerful Sebastian is but stood up to him anyway, just for his young master.
• In chapter 99, Sieglinde has become a Broken Bird after finding out the horrible truth and accepts Ciel's offer to kill her. However, Ciel never intended to kill her and instead convinces Sieglinde to live and use her gift to create "magical medicine" while escaping the forest with him.
  • Though, it should be noted that The Queen did give Ciel a request to bring Sieglinde to her, so YMMV on whether Ciel was genuinely inspiring Sieglinde, really playing mind games with her, or really would have simply killed her had he not gotten that order.
• Chapter 103: It appears that Wolfram is going to shoot Sieglinde while she and the servants are escaping on the train (and at first glance it looks like he did), but he actually shot down Grethe in order to save Sieglinde. This is followed by him apologizing to Sieglinde about having to lie to her, even saying that it was alright if she hated everyone for what they did and that she doesn't have to forgive him.
  • What would have been his last words to her
  Wolfram: "You're not a witch! You're a normal girl."
• Chapter 104. It gives a small look into Wolf's past and how he was trained from a young age into becoming a cold-blooded soldier for the Germans without even being told of their intentions. He was eventually assigned to be Sieglinde's butler/possible executioner, which he initially takes as an insult to his training until he finds the little girl sleeping peacefully on top of a drawing of him and her. Wolf is reduced to tears and claims that Sieglinde had given him "color in his grey world" and swore to fight for her at all costs. This is followed by him waking up on the train with Sieglinde grasping his hand and crying over him.
  • Just the idea that Sieglinde still cares for Wolfram after everything that happened. Seeing that he was specifically the one who broke her legs (albeit unwillingly) and hid the truth from her like everyone else, she could have easily turned to hatred and allowed him to die right then and there. Instead she's absolutely terrified of him dying and is willing (and able!) to perform a bullet-removal surgery on him.
  • Ulterior motive or not, Ciel actually ordered Sebastian to bring Wolfram on the train so that Sieglinde would have someone to look after/protect her, especially since Ciel could have had one of the other servants take on that role.
• Chapter 106 revolves around Sieglinde and Wolfram reconnecting again once he wakes up from his injuries.
• Chapter 107: Even though Lizzie was willing to attack Ciel for what looked like him cheating on her when he wasn't, she went after Ciel and not Sieglinde because she believed he was the one at fault and not the girl he was with (which, in many situations like this, is not the case). However, once everything is explained Lizzie was very quick to apologize to Ciel, not to mention it seems she has accepted Sieglinde as a friend (even giving her the nickname "Suli-Chan/Sully").
  • Also in 107: Even though the etiquette lessons were needed due to the upcoming audience with the queen it was still nice to see Soma call out Sebastian's harsh tutoring tactics on Sieglinde despite it goeing mute. The second time when Lizzie also notices results in her deciding to have everyone help Sieglinde along.

Blue Cult Arc

• Chapter 111: There's just something incredibly heartwarming about seeing Sebastian the Battle Butler, One-Man Army and soul-eating Demon cooing over a cat, giving it a big hug while letting it play with the silver charm, then taking it into the carriage to give it a good meal, even saying that if Ciel weren't allergic he would take the little one home with him.
  • He also briefly shows a bit of pity towards Ciel for being unable to experience the joy of a holding a cat.
• The look on Sieglinde's face when Sebastian gives her the blood samples for her to test is nothing short of adorable as well as Sebastian himself smiling at the sight. Added sweetness since Sebastian was quite ruthless to her during her etiquette lessons.
  • The fact that she has also been getting quite comfy in her role as a scientist and has even found a way to walk on her own is also nice considering her origin.
• Sebastian commending Agni for having Soma's safety and wellbeing in mind when he caught on to how the duo used Soma indirectly for their latest scheme, even going as far as calling Agni "an exemplar butler".
• Chapter 126. Sweet, naïve, obnoxious Soma knew all along that Ciel doesn't care for him nor even like him, and that Ciel is royally fucked up in the head. He doesn't care- he wants to try to help nurture Ciel's potential for goodness, fully aware he might get hurt because he believes the risks are worth it.
• In his final go, Agni showed what it truly means to be a butler by doing whatever it took, up to sacrificing his own life, to protect the life of his master, to the point that Sebastian showed proper respect for Agni's dedication for Soma.
• In general the overall friendly interactions between Grell and shinigami forensic scientist Othello can count, especially considering how opposite they are of each other.

Blue Memory Arc

• Then entirety of Ch. 131 is probably one of the biggest heartwarmers of the entire series, showing that the real Ciel Phantomhive was once a caring sibling to his younger twin brother, the boy that the manga follows, and loved him dearly. Ch. 132 and Ch. 133 have also showed instances of this.

Blue Revenge Arc

• Mey-Rin being taken in by Ciel and given her first warm meal for the first time in her life softens the Cold Sniper. It was this act of kindness that made her leave her old gang and become incredibly loyal to the young Phantomhive.
• Mey-Rin and Ran Mao not only complete their mission at the manor but also manage to do so without any casualties. And once the maids are awakened and freed they gang up on the bastard that took advantage of them and beat the ever-loving shit out of him.
• The flashbacks showing how Bard was once a loving husband and father back in his earlier years, though becomes sad given said wife and child's fates.
  • Unlike many of the characters in the series who were thrown into hellish circumstances before reaching puberty, Bard seemed to have led a good life up until his family was massacred. He also made it a priority to treat the local Native Americans peacefully and with respect before the attack.
  • In a somber variant, even after a Native tribe slaughtered his family and he killed many of them back in retaliation, Bard does acknowledge that the settlers more and more stole away their land and resources and are therefore far from an innocent party.
• Bard's bonding with the "Miracle Nurse" Ada at the Athena Sanatorium by relating to each other in their war experiences. Even when Ada reveals she's been helping to collect blood Bard sees that she's a genuinely good person who's being forced to assist an evil party, and instead of killing her as ordered (since she's an involved party) he gives her a second chance as long as she stops the collections.
  • Ada returning the favor by helping to revive and heal Bard after he takes a massive back stab from Layla.

Anime

• Season one, episode seven where Angela gives Finny a little kiss on the cheek and promises to meet him again. This quickly turns heartbreaking when you realize they never do.
• In episode 1 of season 2, Alois begs Claude not to leave him alone, and Claude holds Alois's face in his hands and declares he'll never leave him alone.
• Season 2 Episode 11: Alois (in Ciel's Body) asking Hannah to tell him that she loves him and give him a hug. Which he's always needed. She does both, which prompts him to cry tears of joy and say "Love is...warm, isn't it?" And this is after all the horrific and humiliating abuse Alois and Claude put her through as well as her own demonic nature.
• The reason Hannah stuck by Alois all this time despite everything? Luka, Alois' adoptive brother, was the first person to show her genuine kindness and gratitude during their contract which led to a total change of heart. She reunites the brothers after fulfilling Alois' contract, and (along with Claude...if only because of Alois' wishes) they are peacefully Together in Death.
• Alois's final wish results in Ciel's immortality. Aww!
  • Not just that, it ultimately saved Ciel from having his soul eaten and put Sebastian, who more or less had been using and corrupting him, into servitude for eternity. Ciel even says something in the lines of feeling a weight being lifted off him.
  • While Sebastian is not happy in the slightest in losing his desired reward, the Kuroshitsuji Red Valentine event shows it actually might not have been worth it as he began entering the Despair Event Horizon from realizing he's now alone and missing both being a butler and Ciel himself. Sebastian might not like it, but it looks like this was the better outcome of the two.
• The OVA "Making of Kuroshitsuji II": The Animated Actors for Grell and Angelina "Red" Dalles appear to be a couple or are at least on very good terms with one another. The two of them arrive together, and despite no longer having a role Angelina shows up on set so she can support Grell (including wiping a footprint off Grell's face after Sebastian kicked her on purpose).
  • Some of the pictures Yana has drawn of the Red Duo long after the JTR storyline has featured them having a girls' night out or being in each other's company. One ticket illustration for a 15th anniversary event also includes the two posing as a couple.
• Another example from said OVA is Sebastian protecting Ciel from falling debris, not even minding that his ankle got broken as long as "his master" was alright. Yet another is when the director allows the cast to give Sebastian a mini birthday party complete with a pretty chocolate cake.
• Small one from season 1, but despite uttering detesting them Sebastian does show a little respect for a dying dog that was deemed bad by a village and was mauled ruthlessly by the other dogs, telling him that he did his job by clinging onto a piece of critical evidence and that he could rest.
  • Though to be fair Sebastian and the group did watch as the mauling went down until Finny put an end to it, and by then it was too late to save the dog's life.
• The ghost of little Prince Richard taking quite the instant liking to Sebastian, even if the sentiment isn't necessarily reciprocated.
• The "Welcome to the Phantomhives" OVA. Removing (or including) that it is a fluffy fanservice episode that puts the viewer in the place of the mystery guest, seeing how kindly most of the other characters treat her is still rather cute. Special mention goes to her turning out to be an assassin sent after Ciel yet Sebastian (though not without grave warning and a possible Stealth Insult) promises to keep the truth a secret, doesn't harm her nor turns her into a Persona Non Grata, and remains just as doting towards her as before.

Movie

• Only if the live-action movie is considered canon, but at least there is a chance that Ciel will grow up and have a family with Elizabeth before having his soul eaten. Too bad that it doesn't just end with Ciel, though.
• In the live-action movie, Sebastian feeding Shiori the antidote before she dies was almost this, until he goes on to say he only revived her because her soul wasn't dark enough and that eating it at that time would be boring/unsatisfying.
  • Though, knowing that despite everything, Shiori is not that far gone yet could count as heartwarming itself.
