Setsuna has an energetic smile and a distinctive style of performing. She's very friendly, charismatic and naturally people oriented. She is easily excitable and full of energy, and she can be moved emotionally very easily. She lights up whenever she is asked a question about her interests, which include anime, manga, video games, and school idols. While she is a very passionate geek and loves to talk about her otaku hobbies with her friends, due to her status as a serious and hard-working student council president, she feels she has to hide them from her mom. When the latter learns about Setsuna, she is happy with it and cheerfully goes to the concert.
