However, even in the absence of a demon lord,
Monsters populated the land.
Someone had to do cleanup; That duty fell to the Capitol Knights.

Raised in the way of the sword and honoring;
As soon as she arrived at the Capitol Knights.
Fearless and selfless, she wants to protect the people.
She's about to achieve her dream.

Go in the woods and retrieve the Wand of Oakmana.
A piece of cake for a girl.
She enters the woods and discovers a cave.
In all her childhood she was never seen before, and on closer look,
A young girl who calls herself a "mana spirit".
The spirit has lived in fear of the monsters.
Was Cynthia here to slay the monsters?
Would she take a side quest?
