Hello!

As far as I remember, the free Jonin Medal or Trial Medal is a one-time reward for reaching a level in the game. On the other hand, the 3 Free Trial Jonin Medals that you are talking about were given randomly to players before and it is not a regular reward but a mistake that happened, I might be wrong about the reason why it was given out since it is a long time ago already but to answer your question, you will never get that free trial medals again. Thank you.

Hello!

I believe I already answered that question in my first reply. The Free Jonin Medal Trial can only be obtained one time per account as you reach a certain level. And if you are talking about the 3 Free Jonin Medals that you got before, read my reply above again. Thank you.
