I really like the concept and the mood.
However, there's barely any animation work here. And what's here is too slow. Way too slow.
These slice of life stories can be slow, because it helps to set the mood. But the animation itself shouldn't be sluggish. It's painful to watch, and hurts me to say because i'm enjoying it.
Even the action scene feels terribly slow.
Also, i think it was a bad way to end this. We know the character respawns when he dies, as it has been shown before in the story, so it's not good to end the animation focusing on his death like he's dying forever, in this dramatized manner.
Keep it light hearted. That had been the tone before he put on the Wanderer outfit.
I did like the expression in his eyes, it's like he's... crestfallen. It's empathic.
