Eu acho que o título é " Sacred Seven " . O menino (Alma Tandoji) tem um cristal dentro de seu corpo que pode transformá-lo. Um dia, Ruri Alba, uma menina acompanhada por seu mordomo e empregadas domésticas, o visita para ajudá-lo a controlar a pedra com seu poder. A princípio, o garoto se recusou. Mais tarde, o menino aceita a ajuda da menina e se torna um herói que luta contra um monstro de pedra.
Alma Tandoji lives a lonely life. One day, Ruri Alba, a girl accompanied by her butler and maids, visits him. Knowing the power of Sacred Seven is latent within Alma, she asks him to lend her his powers. However, he refuses and drives her away since he injured many with his unusual strength in the past.
Meanwhile, a fiendish Dark Stone creature suddenly appears in this peaceful town in the Kanto region. Only Alma's power of Sacred Seven can fight against it. But Alma just lets his power run amuck and things begin to get worse. Ruri raised her gemstone in order to release his true abilities, My Soul I give to you.
With Ruri's wishes engraved in it, will Alma be able to defeat the Dark Stone?
