Othello(オセロ) is a shōjo manga series by Satomi Ikezawa. It was originally serialized by Kodansha in Bessatsu Friend and collected in seven tankōbon volumes. It is distributed by Del Rey Manga in North America. The story is about a shy, naive Japanese teenager with a split personality. The manga is titled after the board game Othello, and not the Shakespearian play. The game involves a lot of switching back and forth between black and white pieces, representing Yaya and Nana's constant flip-flop.
