Allen's father figure who died when he was around ten or so. After he called Mana back as Akuma, his father cursed him, granting Allen the power to see Akuma's tormented souls. Then Allen's Innocence activated for the first time and he destroyed Mana, which in turn led Allen to become an Exorcist.
Before his death Mana worked as a traveling entertainer. Despite Allen thinking about him every now and then during the series, very little is actually known about him until the later chapters reveal that he was the 14th Noah's twin brother who stayed by his side till he died, before further revealing that he and Nea were once the same person - the previous Millennium Earl before the Earl split apart.
- Angsty Surviving Twin: The loss of his twin brother Nea did a real number on his psyche. Especially since its implied either he or the Earl's Suit killed and devoured Nea.
- Broken Tears: http://mangafox.pw/d-gray-man-chapter-219/30/ Just look at his face when Nea dies.
- Death by Origin Story: Or not.
- Disappeared Dad: He died when Allen was around ten, leaving him with no one but his master, Cross. However, it's later revealed Mana apparently didn't exactly die and became/absorbed by the Earl.
- The Faceless: His face is almost never shown in full without make-up in the manga. We get a single panel silhouette of him (as a boy) in normal clothes in the manga with his brother until chapter 214 in a flashback as a small child. He looks exactly like a younger version of the Earl's human form..
- Flower Motifs: In one of Hoshino's Instagram's posts, she mentioned how poppy flowers represent Mana and his brother.
- Ill Girl: Male version of this trope. He seems to have been quite sickly as a child.
- Long Haired Prettyboy: When he was younger.
- Monster from Beyond the Veil: When Allen brought him back as an Akuma.
- Mysterious Parent: Is turning out to be way more important to the plot than we were led to believe at first. He turns out to be the Millennium Earl.
- Nice Hat: Flashbacks show he wore a top hat.
- Monster Clown: Maybe. As the Earl, definitely.
- Posthumous Character: He died long before the start of the series and we only see him in Allen's flashbacks. However, if revelations much later on indicate this might not be true at all.
- Sad Clown: Being responsible for killing your twin/part of yourself before forgetting you did that and then trying to desperately search for your twin who is no where to be found does that...
- Sanity Slippage: According to Cross, after Mana's brother was killed by Millennium Earl he kind of lost it. Which is a huge understatement after the author gets into detail about Allen's backstory in Reverse Novel 3. Turns out that Allen didn't actually have a name in the beginning. He takes up that after Mana calls him Allen, mistaking him as his dead dog. It gets even worse, in chapter 220 a younger Mana is shown crying at his reflection in a mirror, thinking Nea is there and apologising over and over again for devouring him. Mana proceeds to scream and claw at his face till the skin is torn and smashes his hands against the mirror, rejecting how things turned out this way, to the point where the Earl/Adam persona took over and said that 'Nea' and 'Mana's' existence were illusions and that there was only the Millennium Earl, before using a ball of dark matter to destroy his face and memories so they wouldn't be reminded of 'Nea' and 'Mana' anymore.
- Split at Birth: He and Nea actually form the Earl together, they were just two halves of him born separately.
- Split Personality: Implied. Mana seems to be in conflict with his Earl persona, and is unstable because his other half is missing.
- Supernatural Gold Eyes: Even in human form, both Mana and Nea have gold eyes.
- Unable to Cry: Mana mentions when he first meets Allen, he no longer has any tears left even though he's sad.
A kind-looking, cheerful priest on the Black Order HQ.
In reality a strange-looking creature called "Apocryphos", a living Innocence whose role is to protect the Heart at all costs. He is powerful enough to scare a Noah. Seems to be the "Third Side of the War", Marian had previously referred to. Confirmed to be the real culprit behind Cross's attempted murder, but his motives and his relation with him have yet to be explained. Currently chasing Allen to perform something that most definitely is bad news.
- The Assimilator: Has this in mind for Allen.
- Beware the Nice Ones
- Big-Bad Ensemble: He's the newest antagonist; completely independent and loyal only to the Heart, but right up there with the Earl and the 14th.
- Body Horror: His feather-related power.
- Fake Memories: He can implant those in witnesses apparently. While it also works on Kanda, his Healing Factor is able to counter it.
- Feather Motif: And not anywhere that feathers should naturally be.
- Humanoid Abomination: Sentient energy that looks like The Blank, anyone?
- One-Winged Angel: Goes from a kind priest to a weird Blank-ish thing
- Scary Shiny Glasses
- Shout-Out: To Vash The Stampede, Father Anderson (as well as Incognito from the same series), and after being "tooned" by Jasdevi, Charlotte.
- Slasher Smile
- Story-Breaker Power: He singlehandedly counts as "The third side of the war" and in his 2 chapters of combat, it shows. He completely manhandles Tyki and Howard, knocks out Road in 1 hit, regenerates from having a candle shoved through his eye in seconds and is not just immune to, but can also disable Innocences. On top of all this, he can afflict people with a feather-like substance that blinds the affected party and disables their Innonence. He´s the "Grim Reaper when it comes to Noahs".
- The Blank: His real form which does not look right at all, being a white being with no nose and black schlera. But as of Chapter 217, he's been turned by Jasdevi into a Toon form, which is strangely satisfying.
- Winged Humanoid: Briefly displays this, though he doesn't exactly use said wings to fly...
