P3 hits hard and pulls few punches.
In addition to what Zodi said in at least some versions of the story Minato has been experiencing this for a long time.Edit: Also... The **** is up with the protag? Like, "Oh the moon is green and there's puddles of blood and free-standing coffins everywhere... this is perfectly normal." Dude would not last five minutes in a horror movie.
Momento mori. P3 is about our relationship with death, all the way from fear to grim acceptance. Our death and that of others. One of the social links is a young man having to face the fact that he will die before his life has properly begun.
Remember you are mortal. Accept your death, and that of others, but live your life
