The protagonist seems to be completely alone in a dead world (which seems very open), and to interact only with demons and deities, which is good.
According to the cancerous English dubbed trailer, he's been isekai'd to an alternate Tokyo instead of surviving the apocalypse, which is very bad.
If we are lucky it will be like Nocturne and Strange Journey, otherwise that OG Fairy or whatever at 2:07 will never keep her obnoxious bitch hole shut, and she will be part of a party of useless tag along characters who are there just to re-enact animu cliches.
And it better have jap audio. Jesus that fucking English narrating voice was cringeworthy.
