Where did you find this name? What culture is it used in? When were the people you know with it born?
A bit of quick Googling shows a great variety of references to "Mishika" on the web. It looks to me like it might have three completely separate and independent derivations: Japanese, South Asian, and African-American. Which of these cultures, if any, are you thinking of?
