Dramatical Murder

During work at Junk Shop Mediocrity, Aoba Seragaki goes out on a delivery with his Allmate, Ren, and encounters his childhood friend, Koujaku, and his Allmate, Beni. After a short conversation, Aoba makes his delivery to Yoshie and is forced to stay until nightfall. On his way home, Aoba is harassed by members of the Ribstiez group, Bug Bomb, but is saved by his friend and leader of Dry Juice, Mizuki. Mizuki voices his concerns of Ribstiez being overshadowed by the popular cyber game, Rhyme, and tells Aoba of the mysterious disappearances of several Ribstiez groups, rumored to be the works of the mythical group, Morphine. As they part ways, a Rhyme battle soon starts near Aoba and he observes it before meeting up with his old friends, Virus and Trip. The game is soon interrupted by a police officer, Akushima, causing Aoba to hurry back home.

Directly after Aoba's first attack, his normal personality reappears with no memories of what he just did. The mysterious player has his rabbit Allmates relentlessly attack Aoba and Ren again, which causes Aoba's other personality to resurface and seemly destroy the Rhyme Field, ending the battle. Aoba's and Ren's unconscious bodies are safely taken back to Mediocrity by a man wearing a gas mask, who called Aoba "Master". When they awaken, Aoba and Ren both find themselves with no memories of how the battle ended.

The young man silently purchases an item from Aoba, leaving the shop without identifying himself. When returning home from work that evening, Aoba finds the young man in his bedroom, who reveals to Aoba that he was the person in the rabbit costume that forced him in the Rhyme battle. The teenager demands a rematch with Aoba and threatens to destroy Ren if he doesn't. Clear arrives via veranda to Aoba's room, telling the intruder to not hurt his "Master". Koujaku soon joins the group, and a scuffle initiates between him and the teenager. Tae breaks them up and the group settles down in the kitchen, where the young man introduces himself as Noiz. The next day, Aoba and Koujaku visit Mizuki in hopes of cheering him up, as he has been depressed about losing more of his team members to Rhyme.

Tae denies having any connections to Aoba and asks what Takahashi want from her. Inside, Aoba watches a live interview of the owner of the pleasure area Platinum Jail, Toue, and ridicules the man's speech of "perfect happiness". Once Tae enters the house, she lies to Aoba before both of them return to their bedroom. As Aoba muses over his contentment for his current life, he hears singing outside his window and finds Clear on his rooftop. Clear explains the song he was singing is called the "Jellyfish Song" he made up himself and used to sing to his grandfather, who has passed away. When Clear questions Aoba about why humans live the way they do when they are bound to die, Aoba says that humans want to live their lives happily and leave proof of their existence before they do.

Aoba wakes up in Scratch's hideout and quickly suffers a beating from Mink's men on his orders. As Aoba struggles to break free, his other personality briefly takes over and orders the Scratch members to stop before falling unconscious. When Aoba awakens safely in a bedroom with Ren and his bag, Mink states to Aoba that his aware of Aoba's special "voice" and will help him find Tae if Aoba obeys him in return. Although reluctant, Aoba agrees and heads back to his house, meeting up with Clear and Koujaku. Koujaku is distrustful of Mink since his group is made up of criminals, but relents once Aoba explains that Mink will help him find Tae. The group then discovers that Noiz is spying on them and recruits him to their mission. Despite some tension, the group is able to track down Tae's location and Clear guides them to an abandoned warehouse area. They are attack by hooded men, which turns out to be the missing members of Dry Juice.

As Mizuki breaks down, Aoba is pulled into a Rhyme Field and meets Toue. Toue addresses the baffled Aoba with familiarity, and encourages him to discover who he truly is before disappearing. Aoba awakens in the real world, but quickly collapses after spotting an unconscious Mizuki. At Oval Tower, Takahashi reports to Toue about the data they received on Aoba's powers, and that he had sent the police to apprehend him. Later that night at their house, Tae informs Aoba that Mizuki and the rest of Dry Juice were taken to a hospital, but all of them are in a comatose state. She explains that Mizuki was being controlled by Morphine, who works for Toue, and how she was once a neuroplasticity researcher for Toue's labs twenty years ago. Tae quit once she learned that her research was being abused for Toue's brainwashing experiments, but upon her recent refusal to come back to the research labs, Toue used Mizuki to force her to cooperate.
