The Princess of Convenient Plot Devices, Vol. 5 (Manga)

"Princess Octavia finds Sil--and the intruders holding him captive--in the true Sky Chamber, but as she and her allies attempt their rescue, Sil lashes out with uncharacteristic aggression! Luckily, Octavia is armed with knowledge of Sil's past, and she may know just how to help him regain his senses. And when Duke Nightfellow arrives, the conflict seems to turn in Octavia's favor, too...until one of the enemy Adjutants targets her directly. Her bodyguard, Klifford, duels her assailant, but it turns out Klifford is furious with Octavia!"--
