Is light really Kira?

I'm honestly unsure what's confusing here. Yes, Light is Kira. Any time he zei differently, he was lying to protect his identity.

Yes, Light is Kira.

I don't even care that this vraag is a jaar old. This is now the seconde stupidest vraag on this website. WATCH THE FUCKING ANIME. Light gave up owner ship of his Death Note so that Ryuk would be attached to his father. Light had another Death Note hidden in his pants so that he can keep his memories but it was a Death Note that Didn't belong to him so his life span was able to be shown to humans with the Shinigami eyes and he was able to keep his memories as long as he held onto that Death Note.

I'm only at episode 25 but I think he is Kira. He says he is Kira. Where your confusion comes in is how fast he changed from an upstanding straight A student into a cold blooded murderer somewhere around the 24th, at least I think it's 24th, episode. It shows how power can corrupt and the influence that it has over one's mind. Light would not have been murderous if it weren't for the fact that he had that notebook. The idea sorta startled him when he had lost his memory of it.
