The main characters of the series.
    Yumeji Fujiwara 
Voiced by: Nobuhiko Okamoto (JP), Blake Shepard (EN)

A fairly average guy, except that he has the power to see into people's dreams. His encounter with the mysterious Merry Nightmare changes that, and he vows to be her companion and to help her find her way back to the world of dreams. It's hinted that he and Merry have met somewhere before, and because of his abilities and potential, Chaser John Doe speculates that he may be Not Quite Human.

  • Accidental Pervert: Frequently.
  • Achey Scars/I'm Having Soul Pains: Often his right-hand hurts when he leaves a Dream Demon's Daydream. It also hurts when Kyou uses his powers.
  • Ambiguously Human: It's implied that he might be something other than human.
  • Aura Vision: He can see what dreams people experience with his right hand by looking at the color surrounding them.
  • Chick Magnet: To start, he has the obvious affection of Isana, there is a lot of Ship Tease between him and Merry, and there are some mild hints that Yui might like him as well.
  • Chronic Hero Syndrome
  • Curtains Match the Window
  • Fan Boy: Of Toku.
  • Fusion Dance: "Ultra Lucid Gadget" lets him take a Dream Demon into himself and fully access their power and change his appearance to look like the Dream Demon.
    • "Chaser": In addition to John Doe's saw-guillotine, he also gains the belt and cape. He also gets John's mask with ears on the side of his head and his shirt gains a stripe on his right side. Yumeji gains the power of Super Speed.
  • Half-Human Hybrid: Hinted to be this but is really a case of Touched by Vorlons.
  • Heart Is an Awesome Power: Seeing into people's dreams is actually incredibly useful.
  • Heroic BSoD: He gets hit with this after he finds out that Hercules' vessel is his best friend right as Hercules takes over Takateru's mind and body completely. And the only reason Hercules had enough time to do that was because Yumeji promised Takateru that he wouldn't use his 'dream vision' since it made Takateru uncomfortable.
  • I Owe You My Life: His original reason for staying with Merry.
  • Idiot Hair: Even though he's not especially stupid.
  • Invocation: Uses the titles of Dream Demons he's met when using Lucid Gadget.
    Yumeji: "I'll borrow it, <Insert power's name>!"
    or "Lend me your power, <Insert power's name>!"
  • The Lancer: He's not a potent enough combatant to be The Hero, but he can provide excellent support.
  • Living Emotional Crutch: Again, to Merry.
  • Mega Manning: His "Lucid Gadget" ability allows him to replicate the powers of Dream Demons he's previously met. Actually, Yumeji isn't actually recreating their powers in the literal sense, he simply lacks the imagination to create anything original.
    • "Chaser": Replicates the saw-guillotine sword that John Doe wields.
    • "Loneliness": Replicates the giant kokeshi Ichima uses. It can be launched or dropped from nearly every angle.
    • "Lovers": Replicates Chris Evergreen's right hand that can be used as a Rocket Punch.
    • "Chain": Replicates Noir's chain.
    • "Maze": Replicates Landsborough's mechanical clown minion.
    • "Familiar": Yumeji makes a clone of himself like Legion.
    • "Maestro": Replicates a hand puppet that can conduct loud music like what the Achtelnote twins use.
    • "Pharos": Alters the daydream of a Dream Demon.
    • "Hunter": Replicates the weapon wielded by Ren when he fuses with Quartier Latin. Yumeji's Idiot hair also changes to look like a lightning bolt.
    • "Garden": Replicates one of Engi's Sannasubi swords.
    • "Ice Wall": Replicates Hrimthurs' ice.
  • Most Writers Are Writers: Part of the Writing Club. He actually met John and his cat minions in the beginning during his Writer's Block in August.
  • My God, What Have I Done?: By keeping his promise to his friend, he allowed said friend to be completely consumed by the Big Bad. Needless to say, he doesn't take this revelation well.
  • Ordinary High-School Student: Well not including his 'dream vision' ability.
  • Second Year Protagonist: He is a sophomore.
  • Special Odd Hand: Yumeji can see the color of what the person will dream by making a circle with his thumb and index finger of his right hand and looking through it. He has also the ability in daydreams and eventually the real world to create weapons or replicate abilities he has seen with his right hand.
  • Took a Level in Badass:
    • With his Lucid Gadget ability.
    • Gets another one when he used Lucid Gadget in the real world and then Ultra Lucid Gadget.

    Merry Nightmare 
Voiced by: Ayane Sakura (JP), Hilary Haag (EN)

Merry Nightmare is a Dream Demon with severe amnesia. She knows who and what she is (she's a Dream Demon, and for some reason a very powerful one), but she doesn't know how she got from the dreamworld to our world, or why she's stuck here. She is unlike others because she has her own manifestation in the human world. Her only hope of finding a way home is to hunt down other Dream Demons in our world and to find them she needs Yumeji's help. Yumeji has labeled her with the title "Yumekui Merry," or Dream Eater Merry.


STO cafe

    Isana Tachibana 
Voiced by: Ai Kayano (JP), Brittney Karbowski (EN)

Isana is a childhood friend of Yumeji's, a member of the Art Club, and harbors strong feelings for him. She lives with her father and works at the family-owned Maid Cafe, STO Cafe. She quickly befriends Merry, and it is hinted that she and Yumeji met her at some point in their childhood.

    Old Man Tachibana 
Voiced by: Keiji Fujiwara (JP); Andrew Love (EN)

Isana's father, the proprietor of the STO cafe.



    "Chaser" John Doe 
Voiced by: Joji Nakata (JP), Chris Ayres (EN)

A mysterious cat-like Dream Demon that first appears to Yumeji through a recurring dream, having taken an interest in Yumeji and his ability. He is very powerful and owns an impressive army of other cats, which manifest into female kemonomimi during battles. His intentions and loyalties remain unclear, and refers to himself as an "ally of truth", but has nonetheless become something of a mentor figure to Yumeji. He currently inhabits the body of a black cat in the real world.

  • Aloof Ally: Only helps when he deems it necessary.
  • Animal Motifs: Cats.
  • "Awesome McCool" Name: Seriously, Chaser John Doe!
  • Badass Baritone: Both Joji Nakata and Chris Ayres give John a ridiculously awesome baritone.
  • Badass Cape: He even keeps it as a full-on cat!
  • Cats Are Mean: Subverted. He turns out to be an ally.
  • Chainsaw Good: John's weapon is a guillotine-shaped chainsaw-like sword.
  • Cool Mask: He replaces it after Merry breaks the first one.
  • Dark Is Not Evil: He's a sinister figure at first, but it turns out he's one of the good guys.
  • Expressive Mask: His mask can subtly shift between a smile or frown.
  • Funny Animal: He's apparently an anthropomorphic cat.
  • Hero Antagonist: He debuted invading Yumeji's dreams in an effort to take over his body. He later settled for a cat.
  • Improbable Weapon User: Word of Godinvoked says its a cross between a saw and guillotine.
  • In the Hood: He never takes his hood down.
  • It Amused Me: Acts like this at times, such as having Cat Girl nurses treat Yumeji and feigning surprise when he complains.
  • Large Ham
  • Meaningful Name: Like all Dream Demons. He is a nightmare of pursuit ("Chaser"), of being stalked and hunted by a faceless menace ("John Doe") for an unknown reason, across a cityscape that feels familiar, but subtly shifts and changes so you never quite escape, no matter how hard, or long, you run. It's also meaningful in that he is one who hunts after the truth, as a "John Doe" is a pressing question of identity, a mystery needing an answer. He's compelled by his nature to embody his name in many possible ways.
  • Noble Demon: He's surprisingly helpful when it counts.note 

  • Seeker Archetype: Refers to himself as an "ally of truth".
  • Sharing a Body: With a cat.
  • The Smart Guy: A key source of info to the group.
  • Stealth Mentor: All those attacks on Yumeji were preparation for what was to come.
  • Super Speed: He isn't called the "Chaser" just for pursuing the truth.
  • Unusual Ears: The things poking out of his hood.
  • White Mask of Doom: Always wears one. Justified, since it plays into his Meaningful Name.

    Yui Kounagi 
Voiced by: Tomoko Akiya (JP), Luci Christian (EN)

Yui is the vessel of the Dream Demon, Engi Threepiece, but unlike possessed persons that were seen thus far, her relationship with her Dream Demon is a sisterly one of mutual respect. Yumeji and Merry first meet Yui at the supermarket, and soon discover that there is more to her than meets the eye (unless it's Yumeji's eye). There are several jabs at her inability to cook, for which she has been labeled "Magical Chemical Cooking Yui" for her foods' severely distinctive and lethal tastes.

    "Garden" Engi Threepiece 
Voiced by: Aya Endo (JP), Shannon Emerick (EN)

The first benevolent Dream Demon Yumeji and Merry meet. She is blinded by revenge towards Hercules, the Dream Demon that brought her older sister Patty there and ended up killing her. For this reason, she came to the real world, where she met Yui Kounagi. She is currently inhabiting Yui's consciousness, with her permission. She wields (several) swords and eventually, befriends Yumeji and the like.

  • Action Girl: And how! She's one of the toughest fighters around.
  • The Big Girl: Definitely a powerful fighter, although she's not as good as Merry.
  • Cool Sword: Her Sannasubi.
  • Cute Monster Girl: She is an angelic knight.
  • Exotic Eye Designs: Triangular pupils.
  • Hair Wings: Hair shaped as wings.
  • Heroic Albino: She has pale skin and white hair.
  • Hunter of His Own Kind: Unlike Merry, she has no way to send Dream Demons back to the dream world, and she has learned to kill Heracles' underlings in cold blood, although she tries to avoid this now that Merry is around.
  • Improbable Hairstyle: Shaped like wings.
  • It's Personal: Her vendetta against Heracles.
  • Lady of War: Is very kind and polite to anyone she's not trying to kill.
  • Nice Job Breaking It, Hero!: Her killing of other Dream Demons in her vengeful crusade actually help Hercules' plan to damage the Gate. He even thanks her himself.
  • Prehensile Hair: Not just shaped like wings, it can actually be used as wings!
  • Revenge Before Reason: After the battle with the Achtelnote twins, she's pretty much hell-bent on killing Heracles even if it means her vessel's life and having to fight her friends. She gets better after Yui calls her out about it.
  • Rapunzel Hair: Her hair is very long and shaped into a pair of wings.
  • Sharing a Body: With Yui.
  • Storm of Blades: Can replicate her sword multiple times to this effect.
  • Sugar And Ice Girl: Displays shades of this.
  • Sword Beam: One of her signature techniques.

    "Sonar" Clione 
A female Dream Demon whose role is to guide humans to their dream. She was abducted by Hercules and was forcefully implanted into Miyuki Akiyanagi. She was forced to serve Hercules to protect her vessel.
  • Bare Your Midriff: Her outfit is cut to expose her torso.
  • Compressed Hair: Her long hair is kept in her hat.
  • Exotic Eye Designs: Her pupils are + shaped.
  • Horned Hairdo: Her hair has this look.
  • Meaningful Name: Sonar is meaningful for her ability to find and track other Dream Demons by her singing.
  • Nice Hat: She wear a big poofy hat.
  • Sensor Character: She can sing to find and track other Dream Demons. In her Daydream, she can analyze other Dream Demons.
  • Stripperific: Because her outfit is cut to expose her torso, her breasts are only covered by a thin strip of cloth.

    Ren Hinaki 
A junior high school boy in the 9th-grade who does good deeds. He is the vessel of "Hunter" Quartier Latin and goes around suppressing rouge Dream Demons.

    "Hunter" Quartier Latin

Rikka High School

Writing Club

    Takateru Akiyanagi 
Voiced by: Shinnosuke Tachibana (JP), Chris Patton (EN)

Another member of the Writing Club, reflected in his odd habit of composing haiku at random moments, often with completely mundane subjects. As the only other male member of the club, he is shown to be good friends with Yumeji, and there seems to be a budding romance between him and Saki. He's also the unwitting vessel to the Big Bad "Pharos" Hercules.

    Saki Kirishima 
Voiced by: Mariya Ise (JP), Shelley Calene-Black (EN)

A close friend of Yumeji and Isana and a fellow member of the Writing Club, she seems to be fascinated by Yumeji's ability to see into dreams. She is quite confident and outgoing most of the time but notably becomes rather timid when she's alone with Takateru, who she is hinted to like.

    Mei Hoshino 
Voiced by: Natsumi Takamori (JP), Emily Neves (EN)

President of the Writing Club, and unwitting vessel to Chris Evergreen, one of the first Dream Demons that Yumeji and Merry encounter. Chris appears to her as a pen-pal who she only knows through text messaging. She dreams of becoming a novelist.

  • Armor-Piercing Slap: Delivers an awesome one to Chris, and proceeds to forgive him for what he did to her and encourage him to finish his novel.
  • Blind Without 'Em: Claimed to be unable to clearly see Chris's face, but it's implied that she was only pretending.
  • Club President: Of the Writing Club.
  • Cool Big Sis: Is well-liked and respected by her juniors.
  • Girlish Pigtails: Has them in braids.
  • Hair Decorations: Wears a book shaped one.
  • Interspecies Romance: Although not made explicit in the manga, her relationship with Chris bordered on this, and it's implied that she recognized his true form and accepted him regardless.
  • Meganekko: She is a cute girl wearing glasses.
  • Most Writers Are Writers: Her dream is to become a novelist. This actually becomes an important plot point: the fact that she kept that dream even after Chris was removed from her proves that Dream Demons can, in fact, be sent back to the Dream World rather than being killed.
  • Nice Girl: Very nice and even forgives Chris.
  • Star-Crossed Lovers: With Chris, particularly in the anime.

    "Pharos" Hercules 
Voiced by: Kenta Miyake (JP), David Matranga (EN)

The main antagonist and a very powerful Dream Demon. Very little is known about him, except that he is rallying fellow Dream Demons with the apparent intention of occupying the human world and supplanting the human population. John Doe speculates that this is probably not the full extent of his plan. His human vessel is Takateru, a close friend of Yumeji's.

  • An Axe to Grind: His weapon is a massive battle ax.
  • Arm Cannon: He can turn his left arm into a lighthouse looking one.
  • Big Bad: Apparently. Though not the only one.
  • Cheshire Cat Grin: Seems to be perpetually present.
  • Disc-One Final Boss: He takes up most of the antagonist spot for most of the manga. However, he turned out to be a pawn to Greater-Scope Villain who was just loaning Hercules his power.
  • Dark Messiah: Falls somewhere between this and The Antichrist.
  • Demoted to Extra: In the anime, which despite build-up, is never fought.
  • Evil Laugh: Is very fond of laughing maniacally.
  • Exotic Eye Designs: His eyes resembles either a sun or a shining light.
  • Frozen Face / Perpetual Smiler: A cartoonish black-on-white jagged-mouthed grin.
  • Implacable Man: He can tank a lot.
  • Jerkass / Kick the Dog: Yeah, not like it wasn't completely obvious from the start, but after he takes over Takateru completely, he rubs Yumeji's face in the fact that, by keeping his promise not to use his "dream vision" on Takateru, Yumeji essentially let Hercules completely take over his host. Then he taunts Engi about how weak her sister was, stating that his fight with her was boring to the extreme.
  • Light Is Not Good: Frequently associated with light motifs.
  • Meaningful Name: Pharos is the name of several historical lighthouses, including the great lighthouse of Alexandria. He's a dream of guidance, signaling others in their travels. But he's also a dream of flame (as lighthouses had to be lit by fire) and is a consuming destroyer who wishes to burn brighter. "Hercules" is the most obvious part of his name - he is a nearly godlike warrior, impossibly strong and dangerous to have as a foe. And also, as the original Hercules served others in his trials and only became a demigod, so is this Hercules not the true greatest power and instead turned out to be the Dragon rather than the true villain.
  • Mega Manning: He can replicate powers of Dream Demons he defeated. He calls forth the item of the Dream Demon and creates a fiery copy that fights for him.
    "Recollection of the flame: <insert power name>
  • No-Sell: Ignores Engi's Storm of Blades attack like it was nothing.
  • The Unfought: Due to the Gecko Ending of the anime, the protagonists never come across and fight him, despite being established as the original Big Bad between the sixth and tenth episodes.
  • Visionary Villain: Although he's carefully avoided telling his underlings his true purpose, this guy has a clear idea of what he wants to achieve and how he'll go about it. Said goal is to alter the conscious world so that Dream Demons can exist without host bodies.
  • With Us or Against Us: His general approach to recruiting.
  • We Will Meet Again: His parting words to the main characters after they defeat him. Ironically he's killed by another antagonist upon returning to the dream world.

    Kyou Shiragi/Rem 
A boy who appeared before Isana and Yui. He later enrolled in Rikka High School in Yumeji's class. He is later revealed to be a Dream Demon who was behind Hercules and bringing Dream Demons to reality.



    "Maze" Landsborough 
Voiced by: Hiroyuki Yoshino (JP), Greg Ayres (EN)

A notable recurring antagonist, and an underling of Hercules, whom he serves under with pride. While not the biggest direct threat and notably cowardly, his tricks and creations can be quite dangerous on their own. Merry has sent him back to the Dream World.

  • Co-Dragons: Shares the position with Chain, though relying on trickery.
  • Cyclops: He only has one eye and when in control of his host closes one eye.
  • Demonic Possession / Grand Theft Me: Unlike some of the more benevolent Dream Demons, he completely took over his host's body without permission. This eventually caused him trouble, since a host personality not given freedom once in awhile is liable to surface at exactly the wrong moments.
  • Demoted to Extra: Like his boss in the anime, with even his sole fight scene being cut down, removing even his clown Mooks that he used in the original manga.
  • Dirty Coward: Once Merry and Engi get past his tricks, he's an easy target and most likely would've kicked his ass long ago. It's only because of his human host that they lay off from destroying him. Too bad for him, Merry found a way around this problem and locked the gate to their human hosts.
  • Exotic Eye Designs: His pupils resemble the Tick-Tack-Toe symbol (#).
  • For the Evulz: Enjoyed screwing with his host's everyday life and generally acting like an asshole.
  • Genre Savvy: Attacks Yumeji while he's developing Lucid Gadget, and lampshades it by stating that only TV characters give their opponents the chance to prepare.
  • Human Shield: Used his host – more specifically, his host's hopes and dreams – as a shield; having become the embodiment of his host's dreams, killing Landsborough would leave his host an empty shell.
  • Meaningful Name: Uses his power to trap people in a maze.
  • Monster Clown: Both himself and his mooks.
  • Squishy Wizard: By his own admission. Still, claims to be tougher than ordinary humans, but Yumeji isn't an ordinary human.

    "Chain" Noir 
A Dream Demon who faithfully serves Hercules, she operated through the body of a very young girl named Hina who is friends with Minato, the latter whom Yumeji and Merry had previously saved from another Dream Demon. She works alongside "Maze" Landsborough to take down Yumeji and Merry, but they both end up getting sent back to the Dream World. She is portrayed as sadistic and wears revealing clothing, for which she is usually remembered.

A Dream Demon who served Hercules. He was the first Dream Demon killed by Engi.

    "Familiar" Legion 
A Dream Demon that is multiple Dream Demons with one main self. He tried to take over the bodies of 67 humans in Rikka High School with Isana as the main body but were stopped by Merry with help from Yumeji, Mameyama, and Hiroshi.

Kyou Shiragi's

    "Maestro" Achtelnote 
Twin female Dream Demons, Aeolian and Ionian. They wanted Nao to be their shared vessel but were defeated by Merry and Engi.
  • Coordinated Clothes: They wear the same outfit.
  • Exotic Eye Designs: Their pupils resemble music staffs with a whole rest.
  • Hand Puppet: Both twins each have one that holds an F-clef and use them to attack with music. Destroying them makes the twins unable to do anything.
  • Identical Twin ID Tag: Aeolian's hair is more length down than Ionian's who is more rolled shorter. Aeolian also has her hand puppet in her left hand while Ionian wield her hand puppet with her right.
  • Meaningful Name/Musical Theme Naming: Maestro is the Italian word for "master" or "teacher" used for calling a conductor. Achtelnote is German for 8th note. Aeolian refers to the Aeolian mode or the Aeolian harmony. Ionian refers to the Ionian mode or the Ionian School of Music.
  • Musical Assassin: Both sisters can use music as attacks through their hand puppets.
  • Single-Minded Twins
  • Tag Team Twins

    "Ice Wall" Hrimthurs 
A yeti-like Dream Demon that crossed over. Tried to eat Minato, Hina, and Ken.
