Ena is a second-year student at Kamiyama High School, but she only attends part-time night classes. She's the illustrator of the underground music circle 25-ji, Nightcord de. going by the alias "Enanan". Her father was a famous artist. She often draws and posts her drawings online. She has a great sense of social media and would like to get more popular. Kanade saw some of her illustrations online and invited her to join her circle as an illustrator.

Ena is a strong-willed girl. When she draws, she starts living her own world, and disregards everything around her. she thinks that talent is something that she doesn't have but wants. Thus, she claims to hate those that throw it away. She feels inferior and jealous towards those she sees as talented, like Mafuyu. Despite this, she is proud of the illustrations she makes. She gets flustered when her fellow members compliment them, and angry when they do otherwise.She is also described as a "tsundere" by Mizuki. She is also a scared-cat. 

Ena wants attention, as it somewhat gives her comfort and happiness. She is fond of taking selfies of herself and posts them online, and is very proud of them. 

Ena has a mid range voice
