Why is this main character so unlikable, he's got zero merit that would place him in the category of a main character, he's not smart, he's not brave, he's not strong, he's not clever, The disembodied voice is more of a main character than he is at this point.
It's like watching doraemon, whenever the mc has any problem whatsoever, instead of trying to solve it himself he just asks the voice and it has yet another deus ex machina lined up to save the day.
