Megumi Hanajima is Saki Hanajima's younger brother. Saki and Megumi are almost like twins. Megumi cannot read "waves" like Saki, but he can curse people by simply knowing their names. He wears only black along with Saki, and food is almost always on his mind.
Saki and Megumi are alike in almost every way, even more so on inner traits than outer. Saki usually tells people that she and Megumi don't look alike. In one instance, when the Prince Yuki Fan Club were visiting her, and the president tells her that she and Megumi look so much alike, she replies, "No, I don't think so." His favorite food is odango. He has always cared about Saki, and any friend of Saki's is his friend.
When Saki was deemed a witch at school, he prays for the one person that would love her to hurry and find her. Arisa Uotani once told him he sounded like a lecherous old man when he said her mini-skirt looked good on her.
