Mission Description: A local wealthy person of the village needs you to tutor his son in the ninja arts and ways. The boy shows no real talent or promise and the lord refuses to pay you, but you can at least use it as a way to sharpen your own skill by practicing them with the boy. Also he's at least rather nice so it's not much of a hassle.

Since your D rank isnt giving ryo it can give 150 exp. 300 exp are C rank and up missions

I based them off of these.
