ONA
Description
Oni is one of the two central characters of the anime Hentatsu. Her name is written with the Japanese kanji for demon or ogre, which matches her appearance: she is a young woman with a bob haircut, two red horns growing from the top of her head, and a gothic-style outfit. One of her most distinctive physical traits is her right hand, which is colored red from the wrist down. Her exact age is never stated, but the series shows that she is able to drive a car, indicating that she is an adult. She speaks in the Kansai dialect of Japanese, which gives her dialogue a distinct regional character and sets the tone for her casual way of communicating.

Oni has an unusual combination of ordinary modern skills and supernatural abilities. She is highly adept at using a smartphone and operates it with ease, which is one of the ways the series shows her as a contemporary, everyday person. At the same time, she is able to summon a substance called kemurikusa, which she can use as a weapon when attacking. This blend of the mundane and the strange is one of her defining qualities.

Her personality is expressed mainly through conversation. Much of the series consists of Oni talking with the other main character, the cat named Neko, and through these exchanges she comes across as talkative, relaxed, and comfortable in casual social situations. The two of them discuss a variety of lighthearted topics, including stories about dogs and mice, and their small talk also touches on broader subjects such as anime production, past experiences, and various characters. Because the show frequently references the work of its director, her dialogue sometimes serves as a way of connecting the series to those other projects.

In the story, Oni holds a central role: the anime is built around her and Neko spending time in a teahouse and chatting, and their back-and-forth provides the structure and rhythm of the series. She is not driven by a grand goal or a clearly defined external conflict. Her motivation is primarily social, rooted in the enjoyment of conversation, casual banter, and the exchange of stories. The series is not focused on her past, so the origins of her horns, her red hand, or her abilities are never the subject of the narrative, and her history remains largely in the background.

Her key relationship is with Neko, who is her main conversation partner and the character she shares nearly all of her scenes with. The dynamic between them is the heart of the series, and Oni's development happens gradually through their ongoing dialogue rather than through major plot events. Over the course of the show, small details about her habits, her speech, and her way of interacting with others accumulate through these conversations, which is how her character takes shape.
