TAKAGI Kana

The tale of the reincarnated lovers, Hayase Kazuhiro and Fujiki Yoshito, continues in the third series of "Arashi no Destiny."

Hayase Kazuhiro's life was perfectly normal, except that for as long as he can remember, he's had a recurring dream about a princess named Celestia dying the life of her lover, a knight named Arwyth. Kazuhiro's perfectly normal life gets turned upside down, however, when the new transfer student, Fujiki Yoshito, claims to be Arwyth's reincarnation; and if that's not enough, he also says that Kazuhiro is Celestia. The knight-turned-sorcerer has been searching for Celestia for 1300 years, so, to Kazuhiro's dismay, he's not the least bit put off by a silly little thing like gender. Unfortunately, Arwyth isn't the only one who has been searching for Celestia all these centuries. source: https://www.mangaupdates.com/series/wxxubks/arashi-no-destiny
