Suddenly wish he stayed fat and it wasn't an isekai. Would have made for a better story of fat bullied kid goes to prestigious school cause of an act of kindness.
There is like one human in this manga thats an actual person and it kinda the MC.
But still only kinda because he's like only half, maybe even 2/3 trope.
