Reborn as the younger Twin Sister of Hela in MCU! [Up for Adoption]

A successful nurse gets reincarnated into the MCU universe as Hela's younger Twin sister and initially had an identity crisis but got over it quickly. Both she and Hela will have a different fate than in Canon. Notice! MC will be Kayle with a level cap of 1000 but will not be OP from the get-go! She has a Gamer System that gives rewards from different universes such as Fate/One Piece/ Bleach her love interest will be Brunnhilde the leader of the Valkyrie... In this Fanfic, the Valkyrie doesn't die to Hela. The reason I stated that she isn't OP at the beginning is because she will be fighting in the war of the nine realms sure she has Advanced Armament/Observation Haki and very high-level abilities from Kayle but that doesn't even level the playing field on the battlefields she will be on... It will be a 500-year war... The expected amount of chapters for this Fanfic will be anywhere between 300-500 . Without further ado please enjoy the beginning of this Fanfic!
