Sacred Seven

Alma Tandoji keeps distant from others due to a past incident. One night, Ruri Aiba appears at his door. She pleads with him to battle against creatures called the Dark Stone.

Two vehicles scream down the road. Chief researcher, Yuji Kenmi, who ensures the power of the Sacred Seven is not used for evil, is in one. Suddenly, a mysterious man appears.

The students are hard at work for tomorrow's school festival. Alma is helping when a Dark Stone slides onto campus. Kagami hides this from Ruri so the festival won't be cancelled.

The Rock Club is headed to the beach! There’s a legend that the local pyramid is dedicated to the rock gods, much to Wakana’s delight. But Alma senses a Dark Stone inside.

Using Fei’s blood, Naito has created a serum to stop the Dark Stone progression within his body. But the process is too much for Fei. They need a new source for the serum…

Naito has escaped with Ruri, but the transmitter Kenmi placed reveals the possible location of Naito’s hideout. Alma catches up to Kagami, who asks him to investigate the site.

Ruri cannot trust Kenmi due to Naito’s words leading Kagami to investigate. Oni-gawara needs to be fixed, using a stone from Kamakura that express the true heart of a boy and girl.

Alma’s relationship with Ruri gets him teased by his classmates. Slowly, Alma is finding his place at the academy. Wakana is elated that people see him for who he is.

Five years ago, as Ruri’s family, their butler Kagami, and his son spend a fun-filled Christmas week together, Ruri and Aoi have a fight that changes the destiny of the two girls.

Ruri, the current CEO of Aiba Foundation, has been arrested. Alma meets up with Kagami and are attacked by Kenmi’s soldiers.

Kenmi’s laughter echoes through the forest. He’s absorbed Number 0’s energy and plans to consume Alma. Their last battle surrounding the Sacred Seven has begun.
