Alma's power doesn't come with instructions, just collateral damage and regret. When Ruri shows up asking him to be a weapon, the show doesn't pretend this is complicated, it's gorgeous action wrapped around a guy learning that running from your strength is just another way to hurt people. The final episode proves this was always building to something that matters.
Alma Tandoji lives a lonely, solitary life in a port city in the Kanto region. In the past he hurt many people with his unusual strength, and he has sworn off using it. When Ruri, a girl who travels with a butler and maids, asks him to lend her the Sacred Seven power hidden inside him, he turns her away. Then a Dark Stone monster attacks the peaceful town, and only Sacred Seven can fight it. Alma reluctantly calls on his power, but it runs wild and the situation grows even worse. Ruri comes to his aid, raising her gemstone to release his true abilities. Action and science fiction combine across twelve episodes.
