Quick, you have one chance to enter your favorito anime, and change something that happened that you didn't like. Which animê do you enter, and what do you change?

Mello lives and reaches self-redemption.

[Death Note]

Kuroshitsuji

Save Alois!!
I really didn't want him to die :(
But maybe Ciel would die if he didn't die so.. I dunno :s

Hm. Well my favorito animê is Meganebu, but nothing that I didn't like happened in that animê (Except one thing, but if that changed then the whole ending would change)
So I choose my segundo favorito anime, Tsuritama. I'd change ***SPOILER*** Urara becoming their friend???? like he should be taken care of por the government he caused mass hysteria???? he screwed with the whole world???? and now theyre letting him in high school and theyre all friends????? why????? no get rid of him

Not entirely my fave, but I did wish for K project to end without leaving perguntas behind... so many perguntas left behind yet the art was wonderful and the seiyuu list too...
I segundo the notion for Tsuritama on the other hand. I still have the feels...

my fav animê is naruto and of course i would change itachi death i didn't like that at all

Guilty Crown

Inori doesn't die and Shu isn't blind nor does he loses his power or his arm in the end
I never wanted Inori to die so if she lives I would cry in happiness

Mami Tomoe doesn't die in Episode 3.

Fruits Basket, and I would change for Yuki to be with Tohru instead of Kyo

PRETTY CURE.

KIRIYA DIDN'T GO AWAY

Gundam ZZ
Here's what I might change, especially in compilation films:
Make it less campy.
Maintain continuity with Zeta Gundam: A New Translation.
Provide hinting to Sayla's involvement in the series.
Make the show, overall, an easier act to follow.
Alter or remove the infamous Moon-Moon Tribe.

You can watch the show here, starting with either of these episodes:
Episode 1 is a clip show, I recommend skipping it: link
And start with Episode 2 instead: link
After that, maybe you can answer this question: link

Deathnote i want light yagami to live and kill near and spk forces and rule the world with teru mikiami

easy, i would enter Death Note so that i can prevent l and Mello's death. i mean, i would so amor to see them work alongside Near, solve cases together, eat sweets like chocolate XP haha they would have been an epic trio ^_^

I'm between three:
1) I would enter Mirai nikki and Yuno of the first world would live.
OR
2) I would enter Fairy Tail and Juvia wouldn't like Gray.
OR
3) I would enter One Piece and Ace would live.

Fullmetal Alchemist.

***SPOILER***
Hughes Maes death. It would have never happened.

I would enter Kiba: TV Animation and kill Zed before he could screw everything up. Or I would fix the ending so that he and Noah stay together instead of Zed up and leaving.

Death Note!! And I would save L, Matt,and Mello!!!
