Not manga but an absolute 10/10 ending
The ones who failed at revenge,
the ones who failed at their goals,
the ones who fell before achieving their aspirations,
the ones who didn't succeed...
Those who lost, those who stumbled, those who rotted...
Those who fought with all their might, and sacrificed everything, only to have their work be for naught, yielding fruitless results...
Who died unfairly, or perhaps illogically, tragically, without face, full of regrets...
The story which offers a happy future for them, full of hopes and dreams, Katanagatari, quietly lowers its curtains here.
