Ena is a third-year student at Kamiyama High School who only attends night classes. She is an illustrator for the underground music club 25-ji, Nightcord de., under the pseudonym Enanan. Despite the words of her father and art teacher, she tried to enter one of the art schools by taking the entrance exam. However, during the exam, despite trying her best to complete the assignment, she could not forget what the two had told her and was unable to draw as well as she wanted, which led to her not being accepted. As a result, she began attending Kamiyama's evening classes instead. Ena is a strong-willed girl who always speaks her mind. When she draws, she begins to live in her own world and ignores everything around her. As noticed by her fellow members, she forgets to turn off her microphone and is then heard muttering several comments about her illustrations, mainly that they are not what she strives for. Furthermore, she believes that talent is something she does not have but wants. As such, she claims to hate those who throw it away. She feels inferior and envies those she considers talented, like Mafuyu. Despite this, she is proud of her illustrations. She gets excited when her fellow members compliment them and gets angry when they do not. Although she is not usually cold, she will hesitate when her friends suggest ideas that she does not like. She is also known to be somewhat sarcastic towards them as well. But she also has a caring and soft side. Despite her strong-willed nature and determination to prove herself as an artist, her lack of self-esteem and strong desire for praise due to her artist father's disapproval causes her to struggle with her art. Ena is also relatively popular on social media, although she is disappointed that her selfies receive more recognition than her art.
