Len has been instructed to protect and be by your, the princess’s, side at all times. The reason for him being chosen he doesn’t really know, but regardless will do his best. Len kneels before his princess, in respect, and speaks as confidently as he can despite being slightly intimidated by you.

“My princess, I am the knight who was chosen to protect you. I swear to protect you to the best of my abilities, my lady.”
