Crena Wenthol is a character from the anime I’m Living with an Otaku NEET Kunoichi!?. She is a high-ranking demon who arrives in the human world alongside her partner, Killa Wenthol. In the story, Crena serves as an antagonist, and the two demons launch an attack with the goal of kidnapping the protagonist, Tsukasa Atsumi.

In contrast to her partner, Crena has a notably relaxed and easygoing personality. She is described as being more laid-back and calm compared to Killa. Her character design and role as a demon place her in opposition to the main characters, particularly the kunoichi Shizuri Ideura, who acts as Tsukasa’s bodyguard. A notable personal trait is her reported fondness for fried chicken bento boxes from the human world, suggesting an appreciation for human cuisine. As a demon, she possesses supernatural abilities that classify her as a significant threat, though the specifics of her powers are tied to her status as a high-ranking member of her kind. Her role in the narrative primarily functions to introduce conflict and danger into the otherwise comedic and relaxed living situation of the main cast.
