Incredibly awful. I abandoned this anime after five episodes.
It has a good start - destructive earthquakes, lots of death, selfishness, and so on.
However, I laughed when her dad died of an unexploded bomb, and the plot got worse from there.........
Another girl dying of toxic gas, a YouTuber flying in the sky, a British entertainer having nothing to do with the plot, an older man wielding his bow and shooting arrows at his will, a cult having weed........and many other absurdities that can make the audience distract from the fact that this is a disaster anime.
