Sacred Seven

Alma Tandoji, a young man with the power of Sacred Seven, has led a reclusive life due to his unpredictable strength which resulted in injuries to those around him. His life is disrupted by Ruri Alba, who comes from a wealthy background and is accompanied by her staff, and asks him to lend her his powers. A Dark Stone creature suddenly appears in the town of the Kanto region, threatening the community, and Alma's abilities are the only ones capable of fighting it. Ruri attempts to harness his powers by engraving her wishes on a gemstone, but Alma's abilities initially spiral out of control.
