Yo! I was thinking to make the MC do something like mission from someone unknown, rather than doing ninja things and deal his life problems. Below is some ideas regarding the mission part:
1. An anonymous letter sent to MC mysteriously contains the info about the mission. The mission letter will be sent periodically once the previous mission is done. Of course there'll be reward but just after the MC finish all the missions.
2. An unknown man, like MC is from another world. Like in idea no.1, mission will be giving periodically through the man, but this time the man will try to help the MC and there's limit of how many times can the man helps the MC. The reward system will be the same like no.1.
(Anyway, the reward is base on the MC desire)
So, what do you guys think? Should I do it? If so, then which one? Feel free to opinion your thoughts.
