BennettTheSage did a great job with this video, he added emotion while also being informative, and he shared some of his personal experiences.
I have not seen the anime for Barefoot Gen yet, but it seems that it will show some examples of what anime is capable of like Grave Of The Fireflies did.
Here is a scene from Episode 126 (Zero × And × Rose) of the anime (animated) television show Hunter x Hunter (2011) of the end of Isaac Netero’s fight against Meruem.
This is how Fandom describes this scene:
Meruem’s claim of checkmate to Netero continues as they fight to the death.
In his final stand, Netero activates his most powerful attack, the Zero Hand, which does little to no damage to the King.
However, it was Meruem who had been in checkmate all along when Netero activates the Poor Man’s Rose.
