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 died. 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. Pleased that Aoba taught him something and likes his voice, Clear sings to him as he goes to sleep. In Platinum Jail, Takahashi informs Toue that Tae refused to help him once again.
The next day, Koujaku is notified by his teammates that Mizuki and the rest of Dry Juice have disappeared. He informs Aoba and they find that all of Dry Juice's tags has been painted over by Morphine's tags. Virus and Trip claim that they don't know what happened to Dry Juice, but promise to contact Aoba if they find any news about them. Noiz then shows up and challenges Aoba to play Rhyme, but Koujaku interferes on Aoba's behalf and starts another scuffle with Noiz. After Akushima arrives with the police, Aoba separates from Koujaku and receives another download of "Silent Oath", showing a character being taken away from the knight. Confused by the game's contents once more, Aoba heads home, only to find Tae is nowhere to be seen. As Aoba discovers unconscious men with Morphine's tags on their necks, Mink makes himself known to Aoba and knocks him out.
