Prince Freya, Vol. 10 (manga)

Queen Mariam and the people of Asha have valiantly seized the upper hand against Lord Gleb and his Siguardian troops in the fight for their freedom - but just when it looks as though victory is within their gasp, Emperor Dimitri himself arrives with Siguardian reinforcements. If Freya has any hope of helping her people win this battle, she’ll need to escape the clutches of the Indigo Knight before it’s too late.
