Hello. I am Tenjin, the God of learning. I will grant you one skill you wish to aquire. However, you must be specific with your choice as it will increase the chance of the wish being fulfilled, if you are too vague, then you will likely get nothing. For example, saying Arts will yield a 10 percent chance of success; drawing, 50 percent; drawing manga, 80 percent etc. I cannot tell you the exact chances that your wish will succeed, only you will know yourself. And remember, I am the God of learning which means I can only grant you skills that can be learned, I cannot turn back time, or grant you superpowers.
