Just get a Japanese text book like Genki or Minna no Nihongo and follow the syllabus. A japanese tutor will help if resources permit. There is no shortcuts. We all started from はじめまして、どうぞよろしく.
Also anime makes extremely poor learning material imho. It's very over dramatic and full of broken Japanese with irregular conjugation that hinders more than helps for Japanese beginners. Not to mention hardly anyone actually talks like that in Japan.
