Queen Keina rules the Kingdom of Jin from its capital city of Jinzan. She stands among the defining figures of Myoo's history during one of the Empire's most turbulent eras, when the ancient balance among the kingdoms begins to fracture.
After the assassination of her husband, King Satoru, Keina is left to bear the weight of the crown in a time of profound uncertainty. The loss of the man who had ruled beside her leaves a wound that slowly transforms her grief into anger and resentment.
Convinced that Emperor Eien bears direct responsibility for Satoru's death, Keina's hatred for the ruler of Myoo deepens with each passing day. Consumed by sorrow and driven to find someone to blame, she begins to see the Empire as a threat to Jin's future, gradually losing the wisdom and balance that had once defined her rule.
Unaware that hidden forces are guiding her actions, Keina is drawn into a relentless spiral of anger and vengeance that completely changes the way she governs. As queen, she is ultimately confronted with a choice that will shape the future of Jin: accept the order established by the Empire or pursue a new destiny for her kingdom.
The mother of the Shōmashi Mage Natsumi, Keina remains one of the most controversial figures in the history of Myoo. Her story shows how grief, loss, and manipulation can reshape a person's heart and influence the fate of entire kingdoms.
