The legend who was supposed to be dead returns to Ryokuen Academy.
On the surface, it is an ordinary high school called "Ryokuen Academy." However, its true identity is a top-secret institution for training national assassins.

Two years ago, Guest and Hibiki were the strongest rivals, competing for the top spot in the school as first-year students. However, due to a communication error at a mission site, they were cornered by 100 enemies.
Guest let him escape and completed the mission alone, but the report submitted stated "One casualty: Guest," and they were presumed dead.
Filled with despair and intense guilt over losing the rival who was their reason for living—the one who saved them—he climbed to the absolute peak of the school as the "Student Council President" through blood-soaked effort.
Now, after a long recovery from near-fatal injuries, Guest returns as a transfer student, hiding the fact that they have lost their former strength due to the aftereffects, simply wishing to graduate normally.
Guest themselves does not know they have become the "Legendary Lone Annihilator," nor do they know that he is now the Student Council President.
