It is Takeru Ohyama’s first day of his high school life, and his childhood friend Haruko Amaya has come pick him up early in the morning. Takeru is a year younger, and he has his hormones really high and about to burst out.
Takeru tells Haruko that she has become a really cute girl, and Haruko smiles, remembering how silly he can be. On their way to school, Haruko tells Takeru that he has enrolled in a very peculiar kind of high school. It has many differences with regular schools, and Haruko seems a little worried about his friend.
In the end Takeru is more than happy, after all, this is the first year this high school is coeducation. Basically, Takeru knows there will be a lot more girls than guys, and he wants to live a wonderful high school life surrounded by cute girls.
Prety soon, Takeru will find why this school is different, as he finds himself in the middle of a magic battle between students. Suddenly, Takeru sees a girl looking upside down from a tree, she is Kodama Himegami, who is entertained by the fight. Then she realizes that Takeru is watching her uderwear and falls from the tree.
Accidentaly, Kodama kisses Takeru and something strange happens. Somehow, as Takeru runs away, Kodama understands that she has found the enemy she has been looking for.
Now, Takeru understands that this school has very strange rules; they have to dominate an ‘Element’ and fight using certain powers known as ‘Maken’. Takeru is quickly confused, and just to add, he has to fight right away with Kodama.
Kodama is serious, and she really wants to hurt Takeru, but before she does it, someone else appears and saves him. Inaho Kushiya is able to contain Kodama’s power and save Takeru, right after, she says that she is Takeru’s fiancee and hugs Takeru.
Meanwhile, Haruko is confused and angry with Takeru. She visits him and plans to have a long talk with him, but Haruko finds Inaho in the room and both say that the school principal has agreed for them to live together. But not only that, Kodama opens a door and states that she will also live with Takeru, after all, they have something to settle.
Haruko seems to run in anger, but she returns to say that she will also live at Takeru’s place, after all, she is the landlord and has to verify there are not strange activities going on at the student dorms.
Will Takeru find a Maken acceptable for him? What will happen with him, in a school where students get into duels that showcase their magic and combat power?
