Forum:DDK Felgrand targeting itself, negate?

http://i.imgur.com/hlkSftG.png

Opponent attacks with DDK Felgrand, I activate Mirror Force in response to his attack, opponent then responds by using DDKF's effect, targeting itself, negating its own effect but makes it unaffected by other card effects.

My opponent argues that DDKF can target itself, that is true.

My argument: if it negates its own effect, wouldn't it also negate the "but it is unaffected by other card effects."? Wouldn't it then be negating its own invincibility, therefore it would still be destroyed by Mirror Force?

I asked a couple guys after my opponent quit the duel (on Dueling Network), one guy says that DDKF's effect would "linger" even though it targeted and negated itself. Is that true? Could a monster's effect "linger" even after its own effect is negated by its own effect? It doesn't make sense.
