Peach Maki is a female character with black hair and brown eyes, working as a popular idol in the Japanese Hell. Her distinctive style incorporates various peach-themed accessories, aligning with her name. The bizarre nature of her idol assignments leads her to question the true meaning of being an idol in this environment. She contends with persistent stalkers, including the feline journalist Goban, who attempts to capture her in compromising situations for gossip stories.

Prior to her death and residence in Hell, she was employed as a store clerk. This background fuels her enduring distaste for shoplifters, a sentiment that persists in her afterlife role. Her professional responsibilities extend beyond performing, as she later establishes and manages an idol office in Hell, overseeing newer idols like Miki.

She frequently collaborates with Hozuki, a high-ranking demon in Hell's administration. They work together to address issues, including punishing wrongdoers, and coordinate during events like the Hell Festival of Lights. Hozuki treats her with respect, maintaining a cordial dynamic. They occasionally participate in matchmaking scenarios during gatherings such as the gods' annual meeting in Izumo.

In official media, including OVAs, she appears in events like the Goldfish Flower Contest despite her aversion to goldfish plants. This aversion recurs, often juxtaposed with her professional obligations as an idol booked for such events. Her character remains consistent across appearances, with no significant alterations to her appearance or core personality traits documented in the available information.

The character does not undergo substantial development or backstory expansion in spin-offs or other extended media beyond these established details. Her role centers on her identity as a Hell-based idol and her interactions within the setting's bureaucratic and supernatural framework.
