well this might sound a bit stupid and weird but,
"When do you think people die? when they are shot through the heart by pistol? when the get poisoned? when they get incurable disease? no! people die when they are forgotten." then probably add something like, "So, just promise me you won't forget me" then die a dramatic death.
idk why I always imagined myself dying a dramatic death for some reason o.o ....
other than this there really isn't another quote I would use (rather remember lol)
Aaaaye
It's not really a quote form anime but I do love this quote so I'll share it "we bind ourselves together by taking hold of each other's hands, our strength shall be our unity, our way of reason, righteousness and peace, be strong minded- carry no Anger and no grudges"-
not want to use but i am saying this in real life http://www.mangago.zone/home/photo/1957239/
What quote or line would want to use in real life at least once in your whole lifetime. And or a anime line/quote.
