For as long as I can remember I was introduced to the beautiful world of anime when I was in 6th standard. The first anime I ever saw was Gakuen Alice. Suddenly a new world of possibilities and hope opened and since then I have never looked back. As a proud otaku, the thing that interests me the most about anime is its never-ending genres- it caters to the emotions and fantasies of millions. An alternate reality where one can let loose their wings and fly.
