Main characters

Yamato Danjou (壇上大和 Danjou Yamato?)

The story's main character. His family moves from Nami Island to Tokyo. Yamato is the Tokai regional boxing champion. When Yamato arrives at his new school he is shocked to discover that the class was mostly girls. He soon finds out that there some boys there but that there were only nine. He also learns that the girls are the main power in the school, and becomes enraged by this when he is ordered by some girls to clean the girls washroom. He bluntly denies and snaps back at them telling them to clean the washroom. Soon after Yamato engages in a type of war against the girls where he begins to secure a place of power for the boys and even creates a boxing club. Yamato is shown to be extremely strong and quick, as shown when he is able to put a sizeable dent on the class blackboard with his bare hands and knock out an opponent in 10 seconds. Over time however an assortment of girls throughout the school begins to have crushes on him. He is shown as a popular person later in the manga and has not yet formed any love relationships with anyone in the school. But he and Mogami seem to be growing closer and closer together. After an incident where Mogami's kindness reminds Yamato of his mother, he realizes he may be in love with Mogami. When Danjou tells Mogami that he loves her she is listening to her ipod so she did not hear (from Danjous view). It is later revealed the batteries of the ipod were dead and she did hear him. She later admits that she too loves Danjou.

Maki Mogami (最上 槙 Mogami Maki?)

A classmate of Yamato. She is first seen helping Yamato when he was dealing with city thugs. She even gives him her handkerchief, later when she discovers Yamato's name and that he was attending the same school she was, she flipped him with a throw. It is entirely unclear why she dislikes him but it apparently has to do with a past that Yamato has completely forgotten. Mogami is at first shown to be a bossy and rude person who wants things done her way or no way at all and in quite a few instances strikes Yamato for things that are not his fault. Later she still retains her bossy attitude but has mostly faded to insulting Yamato at every possible chance she can get. Despite this she and Yamato seem to retain a love/hate relationship and get along generally well, even though she seem to get jealous easily when girls pay attention to Yamato. Yet Mogami is still troubled by Yamato's seeming loss of memory over an incident that happened on Yamato's home island; an event Mogami witnessed, but won't speak of. When Danjou tells her he loves her her ipod was out of batteries and hears him, but pretends she didnt and that that i pod was on. Later, she admits to him that she heard him and asks him to say it again. After he tells her again that he loves her, she turns him down. Later, she explains to him that she does like him but as long as he can not remember what happened in the past, their relationship can go no further.
