'... It may seem foolish... But if a spirit truly rests there... the spirits may protect my child as we Sylfinnier have protected its Forest's nature...' — Orland thought with hope.
"Since I believe one must protect who one loves... Your Father thinks of this legend as a beautiful testimony of the unlimited lengths one could reach to protect those beloved to us." — The Duke honourably taught the child what he wanted her to also have as belief.
"!" — Nodding to it immediately, Marianne agreed as the foreigner also responded inside. — 'That's right! I've had this belief since before coming here, mister. One must protect and make them happy, so one also can be happy! Do you see, Marianne? Even the duke knows this! Haha. Ain't he clever~?'
