Sawa Yamauchi (山内 沙羽, Yamauchi Sawa) is Kazuyoshi and Masafumi's childhood friend.


Since middle school, Sawa was popular with boys. She and Kazuyoshi held feelings for each other, but were ultimately unable to openly admit them until it was too late. When they were children, Kazuyoshi asked her whether she would rather marry him or his brother. Sawa chose Kazuyoshi.

During her freshman year of high school, she discovered a boy was stalking her. Soon after, when she received a death threat in the mail, she went to the Usui brothers for advice. As a result of their suggestions, she decided to go buy some self-protection equipment. Kazuyoshi, who had been acting strangely, opted not to go and instead she went with Masafumi. Some time after they went out, they encountered Sawa's supposed friend Yukino - who stabbed Masafumi in the chest. As a result of a conversation with Kazuyoshi, Yukino believed Masafumi was Sawa's boyfriend and acted out of revenge for her own ex-boyfriend dumping her in favor of pursuing Sawa. Shortly after Masafumi's death and his brother's subsequent downward spiral, Sawa and her family moved. She couldn't remain in the same town any longer, as it held too many memories and she kept seeing Masafumi wherever she went.


Sawa is a beautiful girl whose hair style has a hime cut and wavy bangs that curls towards her face. Like most students, she usually wears her uniform which sports a blue coat and a short skirt. She also has a mole under her left eye.


Sawa is a kind and playful girl who will tease her childhood friends. In one instance, she gives Masafumi a bear hug and playfully tell him that she will marry Masafumi when Masafumi reveal his latest software. Though, her comment about Masafumi being the smart one unintentionally made Kazuyoshi jealous. Like Remi Misora, she has a tendency to mix words. In Sawa's case, she has trouble with English words such as "stalker."


  • Kazuyoshi Usui: Sawa and Kazuyoshi are very close. In their past, she chose Kazuyoshi as her future husband. It's not known that she was serious until Kazuyoshi confesses his feelings for Sawa. Sawa reply that she feels the same, and she left him with a broken heart.[1]
  • Masafumi Usui: Like her relationship with Kazuyoshi, she is also close with Masafumi. She has no romantic feelings for Masafumi.


  • "Bro, let's go see the fireworks again sometime, the three of us!"[1][2]
