Sekai Saionji

Height: 155cm (5’1”)

Also in year 1, class 3, she is Makoto's classmate. Sitting next to him in class, she sees the picture that Makoto has secretly taken of Kotonoha on his mobile phone. She then helps him get close to Kotonoha despite harboring strong feelings for him. Even though she is good-natured her emotions overwhelm her in many situations. She lives with her mother in an apartment. Known to be both a cheerful mood-maker and somewhat of a loudmouth. Her cute appearance and bright personality (as admired by Taisuke) attract a lot of secret fans, but with her frank and outspoken personality, all the boys who've confessed to her so far have been mercilessly rejected.
