Yumeji Fujiwara

Yumeji is the main character of Yumekui Merry. He is a high school student, and ten years ago, he received the ability to perceive the aura of people's dreams which allows him to predict what kind of dreams they will have.

Personality
Yumeji is a lazy, yet strong-willed and determined person with a heart of gold who is always ready to help others. He is also a member of a writing club at his high school, and is a big fan of the superhero called Guricho. He meets Merry when she falls on top of him as he comes back from his errands, and together, they enter a daydream, a dream that occurs in full daylight. He has firmly decided to help Merry get back to the Dreamworld, even though she is not convinced at the beginning, but they soon end up becoming very good friends.

History
Not much is known about Yumeji's past, but it is said that he might not be a human. In the latest chapters it was revealed that Yumeji is the older brother of Heracles and part dream demon. Chapter 90 reveals that he has been a vessel to an unknown Dream Demon at some point in the distant past, even though he has no memory of the experience.

When he was seven he discovered that he could see the aura of what a person's dream would be.

Plot (Anime)
For several days, Yumeji has been having weird dreams of cats attacking him. He would usually always run from them until the dream ends. However, one night he was having the same dream but it was a little different because there was a whole army of cats attacking him. Just before the dream was about to end, one black cat told him that their boss will appear in front of Yumeji the next time they meet. When Yumeji woke up he was troubled of what the cat had told him. However, despite the dream he continued his daily life. He went to school with his friend Isana who he is living with. While on their way to school, they meet up with Saki and Takakeru (their classmates). Then they all went to school together.

While in school, we see Yumeji with Isana, Saki and Takakeru talking about Yumeji's ability to see people's dreams. He looked at Saki and saw a lot of different colours which determine which dream she is going to have. Then he went to the toilet. There, while washing his hands, he used his ability on himself and saw a black aura around him. This meant that he was going to have another nightmare with the cats attacking him again.

After school, Yumeji went to his after school writing club.



There he talked about his new ideas for a new book which he was writing. He got encouraged by his teacher Ljima who told him that he should always follow his dreams. When the meeting finished, Yumeji headed home. While on his way home, there was a girl who fell on top of him, she was knocked down by crows. He said to her that she should pick her fighting buddies better. Then she said that she wouldn't be friends with birds like that. Then she suddenly notices that her hat was gone and goes off to find it leaving Yumeji behind.

After meeting her, Yumeji continues on his way home. While on his way home he sees the hat that girl was looking for. He picks it up and sees a cat under it. He asked the cat if they met somewhere, then to his surprise he finds himself in the dream he has been having every night. He was shocked because the dream occurred in plain day. There a mysterious dream demon appears. He introduces himself as Chaser John Doe and tells Yumeji that he needs his body in order to come to the real world.

Yumeji terrified by this tries to run away and hides in one house but to his luck John Doe finds him. This seemed like the end for Yumeji, but to his surprise the mysterious girl appears to save him. She introduces herself as Merry Nightmare. She claims that she has been looking for a way to return back to the dream world and asks John Doe to return her home but John Doe was headed the other way (to the real world). Then they begin to fight. While they were fighting Yumeji kept calling Merry's name and helped her defeat John Doe. John Doe left, leaving Merry behind. When Yumeji got out of the daydream he met Merry again in the real world who was demanding him to bring John Doe back. With Yumeji unable to bring him back Merry tries to leave but was stopped by Yumeji. Then she suddenly collapses in Yumeji's hands.

The next day Merry finds herself in Isana's room. She finds out that Yumeji has carried her to his house.

Powers & Abilities
He's able to see what kind of dreams another person will have when he makes a ring with his fingers and looks through them. Different colors he sees determine what dreams will occur although it's only effective 30% of the time. However black auras have a 100% chance of nightmares.

Yumeji also has the ability to use a Dream Demon's signature ability, such as John Doe's saw-guillotine or Chris Evergreen's "Rocket Punch". He names this ability "Lucid Gadget"; and whenever he uses it, his right eye's pupil copies the shape of the corresponding Dream Demon's pupil. As of chapter 88, Yumeji's Lucid Gadget has reached a new state of power allowing him to actually transfer the vessel of the dream demons into himself, which means he can fully copy the entire power of any dream demon instead of just a weaker copy/duplicate of it.

Also, Yumeji is able to enter Daydreams even if he is not a Dream Demon, nor possessed by a Dream Demon. Later in the manga series, John Doe points that this should be impossible and questions Yumeji's humanity.

Finally, Yumeji was able to summon John Doe and his cat army during the battle against Chain Noir, briefly showing the possession of a key-ring similar to Merry's. Chain Noir describes this power as the ability to connect the dream worlds of two different Dream Demons, an ability also shared by Hercules.

It's interesting to note that (so far) Yumeji seems to only be able to use his abilities with his right hand, the same hand that Merry has her scar on, which is also the same hand Yumeji had injured when catching Isana at the playground when they were children. In addition, Kyo Shiragi also has a scar on his right hand, which he appears to have used to send a Dream Demon inside of Sakagami.

Yumeji is immortal in the Dream World.

Yumeji has his own Garden, and finally summons it when fighting Hercules. It is shown to contain a moon, the same as Engi.

Merry Nightmare
Yumeji and Merry have a very strong relationship. When they first met, Yumeji offered to help her get back to the dream world. At first she refused, but as time passed they became really close. Merry sees Yumeji as a person pulling her hand when she needs help. He always encourages Merry when she is in depression. It is also hinted that they may have known each other before, when they were kids.

Isana Tachibana
Yumeji and Isana are like brother and sister, although they are not related by blood. Yumeji always looks for support in Isana. When they were little, they would always help each other. Although Isana gets mad at Yumeji for peeking into the bath when she is taking a shower. When Isana became a dream demon's vessel, Yumeji was desperate to save her dream. After he and Merry revealed the existence of dream demons to her, he became more comfortable talking about it to her.

Takateru Akiyanagi
Yumeji and Takateru are best friends. Yumeji was much reproached for not having been able to prevent Takateru has been possessed by Heracles, but is determined to save him.

Pharos Heracles
Yumeji's arch-nemesis. He is the exact opposite of Yumeji. Yumeji relies on trickery while Heracles uses brute force.

Trivia

 * It is questioned whether Yumeji is a human or a dream demon until Clione reveals he is both.
 * His zodiac sign is Cancer.
 * An ongoing gag is that Yumeji always walks in on Isana when she's taking a bath unintentionally
 * Years ago, when Yumeji explained his ability to read auras to his friends, Takateru asked him to never read his aura, since he found the idea disturbing. Yumeji accepted and is still keeping his promise, thus making Takateru his only close friend he is not checking for signs of Dream Demon possession.
 * Yumeji is revealed to have the same energy signature as Heracles (sound is matched by Clione).
