Minoru Kagenou has been obsessed with strength for as long as he can remember, and as a result, he has put himself through countless hours of demanding training. However, Minoru makes every effort to blend in with the throng, thus this wish is not motivated by a desire to be seen by others. So, at night, armed with a crowbar, he brutally beats the neighborhood biker gangs while feigning to be an entirely normal student during the day. However, Minoru's ambitions appear to abruptly come to an end when he is involved in a truck accident. He bemoans his helplessness in his dying days, saying that no matter how much he trained, there was nothing he could do to go over his human limitations. But rather than After passing away, Minoru reawakens in a different world where magic is common as Cid, the second child of the aristocratic Kagenou family. As soon as he gained the authority he had been seeking, he adopted the alias "Shadow" and founded Shadow Garden, an organization whose main goal is to battle the mysterious Cult of Diablos, a creation of Cid's. The Cult of Diablos is not as fictitious as Cid had imagined, yet Shadow Garden is expanding in terms of both membership and power.
