The Worlds of Harem Anime

Anime has many sub-genres, like most form of media. One of those are the various Harem Anime and Manga. Where a man or woman is place in a circumstance where various people are chasing after them. Bigger then a love triangle or a love square. This will either end in a pair, a harem, or the hero/ine walking away.

So what happens when the Six Infinity Stones arrive in this world, where they grant powers to people in this fight. Well, the ending will change. The World will shift...

And a new story is born.

So will we start with the world, or with a user of the gem stone?
