Ataru Mutsuki, a high school student, possesses a rare ability: whenever he experiences headaches, his intuition becomes incredibly sharp. He is summoned by the Five Senses Detective Agency, a group of Extremers (Extreme Sense Users), individuals who have pushed one of the five senses to its utmost limit. Their aim is to take on the "Brain Breakers," a criminal organization of people with superhuman abilities who commit all kinds of atrocities.

One day, the hero-adoring highschooler Oda Nobunaga, together with his sister stepped into a mysterious other world. There, were all the strongest and famous historical heroes and figures of the Warring Kingdom period. The curtain rises on the battle to decide who the strongest hero is, and who will be the ultimate ruler.
