A girl from Kobe who transferred to Yuna's school. She appeared in episode 30. She speaks in standard Japanese, not Kansai dialect. She has the beauty of a fashion model. Her mother, who longed for a tropical country, is a designer, and Sae's fashion sense is superior to Yuna's. She is a talented and beautiful person. Her father is a doctor, but she is incapable of doing anything on her own, so at first she was vehemently opposed to moving to Izayoi. Like her father, her brother, who has a clumsy personality, attends a high school in Kobe. Her trademark is white sleeveless clothes. She has the courage to punch aliens with her bare hands, and she also has a combative side like Yuna. However, on the contrary, she also has a kind personality. From the middle stage, she possesses a good memory device that is different in color from Yuna. Koji is in love with her, but she doesn't notice it at all. Taka and Masa are also in love, though not as much as Koji.<br /><br />
