The Key to Return Hearts, Ansem the Wise, and the keyblades of hearts theory

[MasterRoxas13 340]

This is a mystery in KH3. Many people have been arguing about if this "key to return hearts", is a keyblade or not. But I have a feeling that it is a fact a keyblade. This KRH ( key to return hearts) is one of the three types keyblades, this keyblade type are the ones made from people's hearts just like the keyblade of people's heart.I have a theory that KRH is a opposite of KPH(similar to how the kingdom key is the opposite of the kingdom Key D.)The keyblade of people's hearts had the power to release hearts, while the keyblade to return hearts, return the hearts of those who do not exist anymore. Now we all know that Ansem the wise was banished to the realm of darkness by his apprentices, then after he escaped, during KH1, he moved to the basements of twilight town gathering knowledge about heartless and nobodies, then he started to use Sora,Riku,Roxas and Namine to get his revenge from what his apprentices did to him. But during 358/2 days I believe that Diz was starting to feel guilty for what he was doing and came up with a idea to bring back Roxas and Namine, since he used those two to meet his goal. The research he found between the time of KH1 and KH2 was a way to find the keyblade to return hearts,so he put the data inside Sora so it can be used to bring back those who cease to exist.The Keyblade of  hearts (Keyblade of return hearts and keyblade of people's hearts) also have the ability to open the other Kingdom Hearts and maybe even close it( the true kingdom hearts can only be opened with the x-blade.) While we know the nature of these two keyblades, we do not known how they were created. However I have a theory that Ansem, the seeker of darkness created the Keyblade of people's heart by gathering the princess of hearts then using the dark keyblade to release their hearts( it was still imperfect due to the fact Kairi's heart was inside Sora during KH1.) I am assuming( since they are opposite) that the only way to find the Keyblade of Return of Hearts is to gather the seven princess of hearts and have them use their powers of light to help Sora create the Keyblade of Return Hearts , or open a portal to the world where the Keyblade of return of hearts is located. Unless the worlds are threaten by the new organization, this would make visiting new worlds almost pointless ( the only flaw I have in these theory).Sora will more then likely use this Keyblade against Master Xehanort and his x-blade( which is a keyblade of the true kingdom hearts). Not sure if Sora will use it as his primary keyblade or just use it temporary after KH3 ( he could just keep both like how King Mickey has both star seeker and Kingdom key D). let me know what you guys think, do you agree with my theory or not. Do you feel like the key to return hearts is a keyblade or not? and if not why?
