Answer

What about Naega Kira?

Answer

I think it would be '저는 키라 입니다' (Jeo-neun Kira imnida)formally, and '나는 키라이에요' (Na-neun Kira-iyeyo) informally. I am not a native speaker, so this could be wrong, but I believe it is correct. I am not sure if there is a slang-y way of saying who you are, though '요! 키라 집에' (Yo! Kira jib-eh) may work. It translates to 'Yo! Kira in the house', I believe.

Hope this helps.
