i didn't like this drama that lasted for 7
chapters based on nothing cuz deku left the school
i call this a bad writing cuz there's no good reason for this long drama
Except there are several obvious reasons for this drama?
Deku is there best chance to lure out the villains, so he decided to go away from UA because he didn't want anyone else to get hurt.
Deku doubles down on this mentality when Nagant gets hurt and AFO singles him out.
Deku's friends first need to save him from his own self sacrificial impulses as well as personal fears.
They then need to change the minds of the civilians, who have been criticized for being an inactive force throughout the series, making them change their mindset ever so slightly to be accomodating.
That last point in particular is literally one of the core thematic conflicts of the series. 'Can society, or people at large change?'
MHA being a rather soppy shonens answers with a resounding yes ina way that ties several plot threads together.
