The volatile partnership between top heroes Dynamight (Bakugo Katsuki) and Deku (Midoriya Izuku) is pushed to its breaking point when a synchronized strike accidentally destabilizes a crucial reactor core, forcing them into a catastrophic, life or death Inverse Strike to save the city. This near-loss shatters their professional facade, exposing a dependency so profound and dangerous that it alarms the Hero Commission. Their intense rivalry is revealed as a secret, stabilizing symbiosis; Katsuki's possessive jealousy is triggered by the threat of replacement, while Izuku affirms that his control is only effective when anchored to Katsuki's chaos. To manage this "volatile element," the agency imposes the Regulator, a dispassionate analyst determined to quantify and dismantle their codependence through mandatory separation. In response, Bakugo and Midoriya wage a calculated psychological war, using coded communication, aggressive lies about their "competitive possessiveness," and defiant, detailed intimacy to protect their bond. Ultimately, they prove that their unstable, fiercely unified connection their "Necessary Symbiosis" is not a liability to be regulated, but the only force capable of saving the world.

Bakugo Katsuki, known to the world as Dynamight, has built his life on strength, pride, and the expectations of everyone around him. He finds himself working alone and living with a quiet longing he's never admitted to anyone. Admiration and respect were never the kind of love he wanted. He yearned for something softer, something real; love that could reach the parts of him he has always kept hidden. One rainy evening, when he least expects it, fate leads him to someone whose loneliness mirrors his own. Kageyama Reiko has spent her life in giving love that never returned. Quirk less, overlooked, and hyper-independent, she learned early to carry everything alone. Behind her gentle smile are years of unspoken hurt, one-sided loves, and the belief that perhaps love simply wasn't meant for her. But on that same rainy night, with tears she tried to hide, she encounters a man who understands that ache more than anyone else. Two hearts that never knew true love meet by chance and together, Reiko and Katsuki begin to learn what it truly means to know love. Disclaimer-I do not own any of the characters from the manga/anime, I only own the original characters I created for this story.
