This is a story that takes place in a fictional city. On a normal day, Naota and Mayumi are together, and a woman with strange behavior suddenly appears - Haruko.
Naota was hit on the head by a motorcycle, and Naota was rescued by Haruko's "artificial respiration", but then he was hit on the head by a guitar, which also opened the beginning of this story.
After that, some strange things kept appearing on Naota's head, but they were solved one by one under the attack of Haruko and the first TV robot that came out of Naota's head - Kenji.
Especially in times of emergency, Naota thinks of his brother, or the mysterious symbol that appears on Kenji's head, which greatly increases his power and overcomes difficulties.
Later, it was discovered that Haruko came here for the purpose of saving her rival and lover, Yate. Later, an unidentified man who seemed to know Haruko very well appeared - Ama. Luo Yu once wanted to stop Naota from helping Haruko, but in the end Naota still chose Haruko...
