Actually both of the person that got transfer or isekaid have no latent powers only normal person transferred to another world.
it just happened Akito was transported in the timeline of the Miko, the Miko Immediately Fell in Love with him.
even though I miko has the ability to resurrect him, she can only resurrect people who had been dead by 3 hrs,
which when the Miko came, the guy has been dead for 3 days already and rotting.
thus she made a wish, that in her life, she wants him to redo everything so she might save his life
