|Mayfly||The Path Left by a Soul|
"Yuzuki" is the 25th episode of the season "Three Vessels" and the 77th episode from total.
At first, Yuzuki doesn't believe Ai's words when she said that Yuzuki had died some time back, but later Ai shows Yuzuki the world that she grew up in.
Originally, Yuzuki lived happily with her parents, until her father, a bus driver, died in a bus crash due to faulty brakes. As the bus corporation shirked its responsibility, the whole town accused the Mikage family of murder and being irresponsible. Yuzuki's mother did her best to keep Yuzuki alive and happy, working at the Oikawa Store, but was eventually forced to quit. Sick and without a means to support herself and Yuzuki, she decides to leave and does so with Yuzuki. Its implied that close to death, Yuzuki's mother planned on killing Yuzuki to spare her from suffering any longer, as she appears to be reaching for her neck as she rests in her arms. She stops, however, when a couple of girls show up at the shrine they were staying at. After her mother dies, Yuzuki buries her mother's corpse beneath the full-bloomed cherry blossoms. Yuzuki's eyes turn a deep red at that moment, and walks away; her last moments as a child are seen, lying on the floor embracing the bear her father gave her.
The now older Yuzuki (who is some kind of an illusion) picks up pictures from the floor next to the corpse of who she now knows to be hers and accepts her fate as Hell Girl. As Ai disappears, Yuzuki is clothed in a red kimono similar to Ai's. Akie somehow returns and acts as Yuzuki's aid. At the end of this episode, a message arrives onto Yuzuki's PC, signaling that someone is summoning her. Yuzuki prepares for her first mission as the new Hell Girl.
