Endfield Doctor, but Able to Use Operator Abilities

What do you mean, I transmigrated into the world of Endfield but became the Arknights Doctor? And what do you mean I can play Arknights inside Arknights?! On top of that, I can use the abilities of the Operators I own. Chen's swordsmanship, Originium Arts, the Lord of Fiends' abilities, Old Man Prime's authority... Wait! Isn't one of those the odd one out? Come on, man! You've got to be kidding me! Is this even still a normal Arknights? But... I guess it's not bad...
