After graduating from the police academy, the police academy group is snatched away by a paper-doll character and sent to correct the opposite world line. They watch Zero's confession get mistaken for a declaration of friendship.
Zero: How can someone kiss me every day and still think of me as a best friend?!
Instructor Onizuka died for unknown reasons at the graduation ceremony. The police academy group swore to uncover the truth.
Before they could find any clues, they were snatched away by Otome Kamishiro, the protagonist of a shonen manga. She said only they could help her save the world and bring the dead back to life.
The way to save the world was to believe in love and courage, and find the villain's true form.
But the villain had the power to travel through time and change the past.
The police academy group discovered that... they had to face their own corrupted versions.
And Otome Kamishiro, a straightforward girl and the strongest fighter of all, coughed up blood after every battle. It turned out her power came at a price.

Because Otome Kamishiro didn't belong to this world, she had to make intimate contact with people from this world to take on its essence.
At first, holding hands and hugging was enough. As time went on, though, it had to become kissing.
Zero was kissed again and again by her, and in the end, he couldn't help confessing his feelings.
Otome: I like Zero best too! I like Zero more than anyone in the world! I want to be your best friend for the rest of my life!
Zero: ...? How can two people who kiss every day be just best friends?!
The four listening in from around the corner: Unmerciful laughter.

Otome Kamishiro felt that Zero had been acting strange lately. He was always saying sentimental things, then dodging her whenever she responded.
The dark version of Zero was even stranger. He said he was jealous that the original could be so close to her, and that he wanted to lock her up.
Dark Zero, that's illegal... Locked in a room, Otome Kamishiro started to feel hungry. With one tug, she broke the chain, then sat openly on the sofa to watch TV and eat.
Dark Zero returned: ???
Otome Kamishiro: Hey, want some pizza? The delivery I just ordered is still hot.
