Comments of chapter undefined of Naruto: Mixed Heritage(Rewrite)

So here's part of the problem with your ranking of missions. D ranks are typically chores, painting, chasing down tora, maybe a delivery to a close by village that is within the land of fire etc... Almost no chance for combat at this level... Your previous mission escorting the merchant should have started as a C rank as any mission with a chance of fighting bandits (normal civies with weapons or ninja school dropouts). No ninja should be fought at this level thus the mission rank increase. You ranked the escort mission as a d which got upgraded to c... where as it should have gone from an initial c to a b B ranks are usually assigned to jōnin or chūnin these missions are common for slightly more experienced genin. Assignments can involve spying or assassinations, and ninja are expected to go up against enemy ninja during the course of the mission. B-rank missions pay between 80,000 and 200,000 ryō.
