Dream Eater Merry

As Yumeji and the others grow concerned about Mystletainn's strength, Chizuru brings everyone into her daydream to meet Lestion, who explains that the only way to hurt Mystletainn is a special gun which uses the agony from killed dream demons and the despair from humans as ammo. As Lestion leaves to do his own thing, Engi shows her belief in human dreams due to the extraordinary nature of Merry and Yumeji. Later, Chizuru mentions that Lestion will die if he fires the gun, becoming afraid that her memories with Isana may soon be erased. After the final exams are finished, Ijima comes to the café and Engi brings everyone into her daydream in order to use her home field to her advantage, but Mystletainn kidnaps Isana and summons a large tree. Engi uses her strongest attack on Mystletainn, but she survives and deals a critical blow to her. With Merry similarly outmatched, Yumeji takes Engi's sword and charges towards Mystletainn.

As Yumeji becomes frustrated about Isana's situation, Chizuru, who had previously thrown away all her emotions following her parents deaths, becomes conflicted between her desire to protect Isana and her duties towards her dream demon, Leon. Yumeji goes to see Yui and Engi, asking for their help in protecting Isana's dreams. Meanwhile, Landsborough witness Pharos Hercules in action as he kills another dream demon, informing him about Engi and Merry, who Hercules sees as no threat. As Yumeji returns home, he is greeted by Chizuru who informs that Mystletainn plans to target Isana, ignoring Yumeji's question concerning whether she is an ally or not.

Having picked up a sprained ankle during his trip to the beach, Yumeji gets it treated at a clinic, which just so happens to be owned by Yui's family. Meanwhile, Isana becomes concerned on what she wants to do after high school. Speaking through Yui as a vessel, Engi apologises to Yumeji for her actions and explains her situation. As Yumeji fetches Merry to go talk with them, they all find themselves in a maze-like daydream, run by the dream demon Landsborough who is under worship of Hercules.

Traumatised by the attack on Yumeji, Merry unleashes a powerful aura that destroys the dream world's moon, forcing Engi to retreat. Upon returning to the real world, Yumeji doesn't have any external injuries, but when he gets home he starts feeling pain and falls unconscious. As he dreams, Yumeji once again meets John, who treats his mental injuries. Meanwhile at school, Saki brings up how many students like Yumi have been suffering from Dream Loss, in which they give up on their goals. John explains to Yumeji that its because of him that Yumeji can enter other people's daydreams, and reveals Hercules is a dream demon who tempted many others into entering the real world. He also mentions that Hercules may know something about Merry, who allegedly entered the real world without a vessel. After Yumeji's wounds heal, John warns him about a strong dream demon named Mystletainn before he wakes up to a worried Merry.

The president of Yumeji's literature club, Mei Hoshino, has been sending texts with a mysterious boy named Chris Evergreen. Later that day, Yumeji, Mei, fellow club members Takateru Akiyanagi and Saki Kirishima bring Merry along to karaoke, whilst Isana tries to make friends with a transfer student named Chizuru Kawanami. Later that night, when Mei comes to Yumeji's family café having supposedly been stood up by Chris, she suddenly acts weird and texts herself from another phone. Yumeji realises that Mei has become a vessel for Chris, who is actually another dream demon, and chases after her, ending up in her daydream. As Chris prepares to attack him, Merry arrives and defeats him. Before Chris disappears, Mei asks to look at him, and comes off happily from what she sees. From that point, Yumeji decides to work together with Merry to help her find nightmares, and she starts working part-time at the café.

Merry suddenly collapses, so Yumeji takes him home where his friend, Isana Tachibana, and her father help look after her. Merry explains to Yumeji that she had been hunting dream demons, trying to find a way back to the world she came from, only to be met with more questions. Later that night, Merry decides to leave to do things on her own, whilst Yumeji settles his resolve to help her. Meanwhile, a girl named Yumi with dreams of becoming a nurse suddenly ends up in a different dream world with her resident dream demon, Serio. Serio is suddenly killed, which causes Yumi to lose all drive in her goals.
