Description
Merry Nightmare hails from the Dream World, where she functioned as the Gatekeeper safeguarding the boundary between dreams and reality. Her duties involved guarding a vast collection of keys linked to dream demons' domains and regulating orderly passage between realms. Uniquely among dream demons, she possesses her own physical form, eliminating the need for a human vessel in the real world.
Approximately a decade before the main events, a young human named Yumeji Fujiwara accidentally breached the Dream World. During his intrusion, he tampered with the intricate key organization system Merry maintained. While chasing a misplaced key, they encountered the dream demon Rem, triggering a chaotic incident that swapped Rem's right arm with Yumeji's. This event unleashed a vortex that violently expelled both Merry and Yumeji into the human world, stripping them of their memories. Merry materialized with no recollection of her past or purpose, bearing only a distinctive scar on her right wrist that mirrored the wound Yumeji sustained.
Physically, Merry resembles a teenage girl with purple hair and striking green eyes featuring horizontal rectangular pupils that shift between black and white. Her signature outfit comprises a white hat adorned with a pink closed-eye insignia and ribbons, a white overcoat with curled coattails, a midriff-baring camisole top displaying a "Z"-like pattern, a white skirt, black-and-white stockings, and black shoes bearing the same closed-eye symbol. She consistently conceals her scarred right wrist beneath a cloth wrap. Subtle sheep-like characteristics include pointed ears often hidden by her hair.
Personality-wise, Merry bubbles with restless energy and fierce determination, yet frequently stumbles over social tact, delivering poorly timed remarks. Initial reluctance to accept help gradually yields to deep trust in Yumeji after he vows to help her return home. She develops passionate attachments to human experiences, especially doughnuts (which become her trademark favorite) and video games, while displaying a distinct aversion to spicy foods and carbonated drinks. Emotional vulnerability surfaces when she learns her actions might have killed dream demons instead of banishing them, leading to despair and attempts to push companions away.
For ten years, she wandered the human world before literally falling from a tree onto Yumeji, rekindling their connection. They partner to investigate dream demon incursions into reality. Merry combats these entities using hand-to-hand fighting and a specialized keychain capable of forcibly returning dream demons to their realm. Her latent abilities as Gatekeeper awaken more fully under extreme duress, especially when Yumeji is endangered, unleashing reality-altering power that shatters dream dimensions and summons physical gateways between worlds.
Key developments unfold through conflicts. When the dream demon Engi Threepiece attacks and Yumeji shields her, sustaining near-fatal injuries, it triggers a berserk state: Merry's eyes glow red and bracelet-like keys materialize, shattering Engi's weapons and the surrounding dream space. Subsequent story arcs progressively restore her memories, unveiling her original identity and purpose. The final conflict against Rem's plan to merge realities forces Merry to fully embrace her Gatekeeper role. After aiding in preventing the fusion, she bids farewell to Yumeji with a kiss and returns permanently to the Dream World. Though the separation erases humanity's memories of dream demons, Yumeji retains enough impression to write a novel based on their experiences.
Relationships define her journey. Her bond with Yumeji evolves from mutual utility to profound interdependence, rooted in their forgotten childhood encounter and mirrored scars. Interactions with Yumeji's childhood friend Isana Tachibana involve initial jealousy that matures into mutual respect, particularly after recognizing their shared connection through the playground incident that caused Yumeji's scar. Alliances with other dream demons like John Doe and former adversaries like Ichima broaden her perspective on human-demon coexistence.
Employment at the Tachibana family's STO café integrates her into human society, where she occasionally wears a maid uniform. Despite her otherworldly nature, she demonstrates a capacity for human-like aging during her decade in the human world, appearing in child, pre-teen, and teenage forms across flashbacks and the main narrative.
