Reincarnated as Glorfindel and reincarnate in a mixed anime verse?

Tell me what you would do if you were sent to Middle Earth after dying replacing one of the best heroes in this universe; flee, imitate or change sides....

Now what would you do if you were sent to Middle Earth after dying replacing one of the best heroes in this universe during the great adventure that would classify him as a God-killing hero?

- The protagonist has a Character Template System, but if it is random, that is, I will make a roulette in which I will put the characters and whoever comes out...

Warning: The story is Harem! and that does not mean that just for that reason it is bad, because if that were the case, stories like Mushoko Tensei would not be successful, the harem is not the problem, it is an option that you can read and if you don't like it, that's fine and if you like it, it's also Well, they are 'Your' tastes at the end of the day, that's the end of it.

Notice: I do not own anything in this novel, I am only writing it, if the author of the novels or the art so wishes, they will be unsubscribed. It should also be noted that I am not a professional author and that is not a serious hobby. so I won't be updating often, thanks for listening

I think that's all and once again many thanks to the great J.R.R. Tolkien (John Ronald Reuel Tolkien) the creator of the entire Lord of the Rings literary series to Takeru Uduki the creator of Isekai of Cheat Skill and its books also to Reki Kawahara the creator of Sword Art Online and Aka Akasaka the creator of Kaguya- Sama Love is War!, thank you very much for your great works and this fanfic is merely an expression of my fanaticism for the universes you have created.
