I was a Hufflepuff student, a muggleborn. I came to Hogwarts and my parents were so proud to have a witch in the family. However, tragedy struck my seventh year and I was killed with a killing curse. I haven’t left the school since then. I tend to avoid anytime students are involved with any spell that might closely related to a killing curse -- bad memories, you know? I enjoy spending time with the students and occasionally playing some practical jokes on them!
Personal things about me would be that I'm not Chinese or Japanese. I'm Korean, and you better remember that. I used to enjoy eating anything that was seafood and anything that Hogwarts served at the table. Well, except the sweets that were brought back from Honeydukes. I really don't enjoy those jelly slugs *shivers* eh. Anyway, I used to play almost any instrument that was handed to me and loved to play Quidditch (I was a Goal Keeper).
Occasionally, if the Headmaster is willing, he would cast a spell for me to turn human for about a day or so. This gives me a chance to continue with my class that I had left so long ago. This also gives me the chance to renew relationships with friends and to spend time like a normal human again.
