Megumi is ranked 4th in school and is Jun's older twin sister. She is the daughter of a famous vocalist and music producer and shares her brother's love of music. She is a cute and nice girl with long curly brown hair, who rarely joins in disputes. Megumi is always quiet and refuses to speak because she wants to save her voice for singing. She usually writes on a sketchpad to communicate with others, but will speak when deeply upset (usually in the form of a shout), which generally have devastating after-effects. She rarely speaks to people normally on a consistent basis with the exception of Yahiro, who encourages her to sing. Her singing usually causes all who listen to her to get knocked out, however Yahiro theorizes that she probably sings very well, but that it needs to be in an open area and at a great distance. She proves this theory correct when on an involuntary date with him, she sings to him from the top of the stairs. She initially asks Yahiro out because she was trying to prevent him from sabotaging Tadashi and Akira's relationship and sings to him partly out of pity and partly because of a 'game' they are playing. However, they soon begin to develop feelings for each other, much to Jun and Ryuu's horror. Like Jun, she is very close to Ryuu; she can be fiercely protective of them both, and thinks of Ryuu as much of her family as her brother. Megumi also happens to be bad at sports and dislikes athletic activities.
