Suddenly Princess

Princess Minerva enters a tournament that offers the winner a fortune. But when her bodyguard gets kidnapped by an evil sorceress, things really start to heat up.

Sshhh! Princess Syalis is trying to get a good night's sleep. Some shut-eye. Forty winks. Catch some Z's. Long ago in olden times when people and demons lived together in—well, disharmony, really—a demon king kidnaps a human princess and imprisons her in his castle. Bereft, the princess's subjects beat their chests in anguish…until a hero arises to spearhead Project Rescue Our Princess! While waiting for her knight in shining armor, what's an imprisoned princess to do...? Teddy-bear guards with bat wings are all very well, but her dungeon cell is bo-o-o-ring! So, she decides to wile away the long hours by sleeping. Now if only she could get comfortable…and didn't suffer from insomnia...

To retrieve the talisman stolen by her beloved, Tiara hunts the night, battling monsters with her awesome shamanic powers. Disguised as an ordinary schoolgirl by day, she arrives at his lair only to find her archrival on the scene... protecting the thief. Dark secrets unravel as Tiara faces these powerful opponents, and her one hope for survival may be to betray her mission.

Doris Ruridou is young princess who had just entered Teito Academy. She is also a Panzer, a person with special abilities and fights with a weapon called a "tool". Shortly after entering, her older sister shows up to teach her how to fight as a Panzer against other Panzers who challenge her.
