All anime has an amazing plot and appeals to you. BUT it's all dubbed by 4Kids Entertainment .
You can enter the world of any anime of your choosing only one time. BUT once you enter that world, your favorite anime character from that universe dies and can NOT come back to life.
Every anime that needs another season gets another season. BUT your favorite anime seizes to exist.
Hetalia becomes real and the leaders of each country is what they are depicted as in the series. BUT you become the new Hitler. (Just to clarify you commit genocide as a more modern Hitler, No you are not world war 2 Hitler so you can't stop the holocaust from happening.)
You are able to live in a harem with all your waifu's/husbando's. BUT you are not aloud to kiss or do anything "sexual" to them or else they'll die instantaneously. (Cuddles are okay)
BUT your least favorite fandom will also get an anime adaptation and be considered better than yours by the anime community.
