World Break: Aria of Curse for a Holy Swordsman

Haimura Moroha has the memories of two past lives. He meets two girls, Ranjou Satsuki and Urushibara Shizuno. Their past and present lives begin to intertwine.

Moroha and Shizuno join the Strikers. Satsuki is frustrated by her lack of ability, but one weekend, she faces down a Metaphysical at the shopping mall.

Edward, one of the six Rank S Saviors, comes to Japan. Meanwhile, Shizuno refuses to talk about her past life, causing friction between her and Moroha.

Chained down by her family, Shizuno has been repressing herself. Edward appears before Moroha, who struggles to set Shizuno free. Moroha's other past life awakens.

Summertime. And beaches! The Strikers at Akane Academy head to the beach for summer camp. Satsuki and Shizuno choose their swimsuits carefully, and Moroha has fun hanging out with Haruka, Tokiko and the others.

Another Metaphysical arrives, and without anyone coming to their aid, Moroha and the Strikers are forced to fight it themselves.

A new student arrives from Russia on exchange, immediately confessing her feelings towards Moroha. Moroha is accommodating, but Shizuno has suspicions.

Lesya's true identity is revealed: she is a maneater -- an assassin. As they take swings at each other, Moroha's holy sword awakens.

Moroha challenges Russia Headquarters to a fight on Lesya's behalf. With Edward's support, they arrive in Russia.

Moroha goes to Russia in pursuit of "Lightning Emperor" Vasilisa, and finally finds her, and is confronted by many of her thugs.

Moroha and the others take a break after their battle in Russia, but the peace doesn't last. Another enemy, apparently waiting for Moroha's absence, has attacked Akane academy.

A massive dragon threatens Akane Academy. The Strikers are prepared to fight against it with their lives.
