ProtagonistsThe main characters of the series.
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 he is really a case of Touched by Vorlons.
- Heart Is an Awesome Power: Seeing into people's dreams is actually incredibly useful.
- Heroic B.S.O.D.: 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.

- "Garden": Replicates one of Engi's Sannasubi swords.
- 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.
- Action Girl
- Adaptation Dye-Job: On the manga covers, her hair seems to be dark indigo, but the anime changes it to more of a burgundy.
- Curiously, this doesn't just apply to her hair; there's no real indication of this in the original art, but the animators make Merry's skin slightly pinker than everyone else's.
- Adorkable: Mainly when Donuts are involved.
- Animal Motifs: Sheep, frequently lampshaded.
- Badass Adorable: She's pretty damn cute for a demon, but don't let her petite body and stunning looks fool you, she's one hell of a powerful girl.
- Bare-Fisted Monk: Fights with fisticuffs, in comparison to every other character.
- Bare Your Midriff: Constantly. The anime even treats it as Fanservice — instead of Panty Shots, we get gratuitous closeups of Merry's bellybutton.
- Subverted in the beach episode; Merry doesn't own a swimsuit, and the one Isana lends her is her old one-piece from school.
- Barrier Maiden: Merry IS part of the system that keeps the dream world separate from ours. Her getting stuck in our world is one of the things that allowed Heracles to rise to power.
- Berserk Button: Don't ever hurt her friends, especially Yumeji.
- Betty and Veronica: The Veronica to Isana's Betty.
- Catch Phrase: "I have no hopes or dreams."
- Chest Insignia: Arguably the symbol on her camisole top is a stylized Z with the top line going all the way around.
- Cute Bruiser: John actually wonders aloud how she can get so much power out of such a small body.
- Cute Little Fangs: She has them.
- Cute Monster Girl: Being a female Dream Demon.
- Dangerously Short Skirt: Never gets a Panty Shot, but she's still every bit as tough as the average Action Girl.
- Dark Is Not Evil: Is a Dream Demon, but without a doubt, she is on our side.
- Does Not Like Spam: Dislikes carbonated drinks.
- Exotic Eye Designs: Her pupils are horizontal rectangles.
- Expy: Possibly inspired by Maribel "Merry" Hearn.

- Gamer Chick: She enjoys playing video games.
- Get a Hold of Yourself, Man!: Does this after Yumeji starts blaming himself for Takateru's mind being completely consumed by Hercules.
- Heartbroken Badass: When one misunderstanding almost gets Yumeji killed via Taking The Sword, Merry's rage is sufficient to cause her to Take a Level in Badass right then and there.
- The Hero: Mostly by default, but she's pretty well-suited to the role.
- In-Series Nickname: Yumekui Merry, of course.
- Impossibly Cool Clothes: Her coat's coat tails are somehow always curled.
- Lightning Bruiser
- Male Gaze: As noted above, she has a lot of shots focusing on her exposed stomach.
- Manic Pixie Dream Girl: She definitely manages to make Yumeji's life more interesting, although he wasn't an Ordinary High-School Student to begin with.
- Meido: Her work clothes.
- Monster Roommate: Since she doesn't have a place of her own, staying with Yumeji and Isana is the obvious solution.
- Ms. Fanservice: She can play this off good, due to her good looks, and Bare Your Midriff & Male Gaze shots.
- Nice Hat: She almost never takes it off — which is only to be expected, considering she was created by an author who used to be best known for Touhou doujinshi.
- Nice Shoes: Merry wears slip-on shoes with a closed eye sigil design on the toe box of each one.
- Pointy Ears: Has them but are often hidden.
- Security Blanket: In the first episode, she misplaces her hat, panics, and stumbles away from Yumeji mumbling "My hat, my hat, where's my hat..." When she later recovers it, she explains that she's just not comfortable without a hat on.
- She-Fu: How she fights.
- Sigil Spam: Her jacket, hat, and shoes have the symbol that is like the top arch on the Gate. It looks like a closed eye.
- Stripperiffic: Indeed. Her attire includes clothes such as a top which leaves most of her stomach exposed, a short skirt that displays her legs rather nicely, and of course the obligatory thigh-high stockings. Which makes it quite amusing on h
- Super Toughness: Dream Demons can be hurt, but they — especially Merry — can take a lot more punishment than ordinary humans. For example, there's a scene in the manga, where Merry, Yumeji, and a few others have stumbled into Maze's dream space, that involves Yumeji about to be hit by a robotic clown wielding a giant sledgehammer; Merry leaps in, takes the hit for him, and proceeds to beat the robot into scrap while shouting "THAT... HURT!!"
- Took a Level in Badass: Once she remembered her role as "Sheep", the gatekeeper of the "Gate".
- Trademark Favorite Food: Donuts. She adores them.
- Trademark Least Favorite Food: She can't handle carbonated drinks.
- What Is This Thing You Call "Love"?: Claims not to understand love and other such human emotions.
- That said, after having been asked whether or not she liked Yumeji by Isana (prompting the above claim), she begins to list all of Yumeji's good qualities and how important he is to her, prompting Isana to muse that Merry's feelings are "liking someone."
- You Gotta Have Indigo/Burgundy Hair
- Zettai Ryouiki: Grade A with white socks with black stripes.note
Maid Cafe, STO Cafe. She quickly befriends Merry, and it is hinted that she and Yumeji met her at some point in their childhood.

- The Chick: Shares this position with Yui.
- Childhood Friend Romance: To Yumeji.
- Girlish Pigtails: Has them when she uses hair ties.
- Hair Decorations: Wears hair ties on her pigtails.
- Hollywood Pudgy: Invoked. She's very insecure about her weight, and occasionally teased about that insecurity, but she still looks cute and petite to the audience and none of the other characters seem to actually care.
- Chapter 39 takes this to another level.
- Idiot Hair: Like Yumeji, she's not particularly stupid, just not a genius.
- Meido: Part of her job.
- Missing Mom: Her mother died prior to the start of the series.
- Nice Girl: Unless Yumeji walks in on her at the wrong moment or a guy talks about her weight.

- 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 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.

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.

- Pinocchio Nose: She has a tell when she is lying; when she lies she touches her hair with her right hand.

Rikka High School
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.
- Beta Couple: With Saki, probably.
- Black Eyes of Evil: When Hercules is in control. Brrr.
- Camp Straight

- Expy: Only other guy in a club alongside the male protagonist, a very cool head, a slight but near-constant smile, bishonen facial features... does he remind anyone else of Itsuki Koizumi?
- Implausible Hair Color: He's blond, and there's no indication that he's But Not Too Foreign.
- Long-Haired Pretty Boy: It wouldn't be worth mentioning if it wasn't of comparable length to—perhaps even longer than—both Merry's and Saki's.
- Most Writers Are Writers: The most blatant example.
- Nice Guy: What he comes across as overall.
- Perpetual Smiler: Not as jarring as most examples.
- Though it turns into a Slasher Smile when Hercules takes control.

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.
- Beta Couple: With Takateru.
- Freaky Is Cool: Is quite interested in Yumeji's ability, and lets him check her dreams out for her.
- Genki Girl

- 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.

- Big Bad: Apparently. Though not the only one.

- 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.
