Age 15, the day I became a lady
In a valley between two loves
On the day of the duel, the one I love...
Road to Versailles
Escape in a hot-air balloon
News of big brother's death in battle
Now, the birth of a beautiful swordslady
Appearance of the mysterious Bat Gang
Love burning in the night fog
Love blooming on the battlefield
I hate the war that killed mother
Midday dance party
Departure for a new life
