Avsnitt 4

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.
