Regardless of what anybody said, he went away on his own.
This started the great rise of the Shield Hero. He knows in order to survive he can’t trust anyone anymore.
After that, the hero made some acquaintances. And he eventually cleared his good name. In all of the series, I believe that the Twenty-First episode was the most satisfying to watch.
The bitch Myne got what she deserved. I think all of us had enough of her and would have loved to see her neck getting sliced in half, we would have loved seeing her dead and quiet.
Naofumi just HAD to step in and save them, now we’ll have to see her again in the next season or perhaps even after that.
Let’s just hope that they kill her in the next seasons! (All hate Myne)
And just like that Naofumi regained the trust, respect, and honor he had once lost.
