Seirei Gensouki - Spirit Chronicles S01E12 - Fated Reunion

The moment the carriage carrying Celia arrives at the great temple where the wedding is being held, a dark figure darts toward her, threading nimbly through the crowd. The figure who so easily overpowers the knights acting as guards in order to steal Celia away is Rio. In the face of Rio's straight-forward emotions, asking Celia once again what her will in the matter is, she finally speaks her true feelings... Then, a beam of light shoots upward from the royal capital. The same thing happens in other places in the Strahl region until six pillars of light pierce the sky...!
