It is a strange anime that starts out with a good amount of violence.
Opening scene has a young man who is off to go train to be some sort of somewhat mysterious order and he is talking about it with everyone on board the truck they are on. He says that he is going to go and train to come back to rescue his girlfriend or childhood friend from the evil tyrant who rules the area. He seems hopeful that he can do this. There is an older man who says very little on the trip.
Suddenly there is an explosion and the truck crashes. Everyone on board is dead except for the older man. Young boy included. It was raiders. Monsters that wanted easy prey. The old man is surrounded. He flips back his coat revealing a bomb and he says to the monsters that he’ll blow himself up if they try anything. He negotiates his way out and leaves. The monsters begin to happily eat the fresh meat of the people who had died. As they get down into it. Turns out the old man had another explosive planted on the young man’s corpse. It explodes and takes the swarm of monsters out as the old man sets out towards the tyrant’s kingdom.
The childhood friend/love interest of the young man has been made bride/wife to tyrant. She has also been augmented to the fucking gills so she acts as his unwilling guard. And was augmented enough that trained soldiers would probably be fodder to her. I don’t know if it is tech or mind control that is making her do that.
Old man shows up wearing a copy of her childhood friend’s face that he produced with a strange amulet or talisman. Turns out the old man was part of the strange order. He just seems to have some health condition that makes fighting rough on him. Low stamina. He pronounces judgement on tyrant man who laughs and basically snaps his fingers to get the lady childhood friend of the young man to get ready to fight. So him and the lady start throwing down. She is pretty well pressing him into a corner. I can’t remember the whole fight but she either overcomes the mind control or he manages to take her down softly instead of killing her. Tyrant man basically shits himself at that point but he gets what he deserves and dies.
The childhood friend felt indebted and begins to try to follow the old man around. And he eventually tells her to fuck off and he wants to be alone.
But eventually the two end up in a strange village together. Where people are missing or there is some sickness. Which starts out just a bit off before going into full fever dream.
People keep disappearing and things keep happening. And slowly they have to make their way through it to find the truth. A young man in the village travels with them. As things progress it turns out the village was an actual ghost town sustained by the wishes of the spirits there. Some godlike deity or pseudo deity was behind the whole thing because they didn’t want to die. The old man, young man, and girl manages to fuck it up. But after they do the young man realizes he is dead too. The old man affirms this. So he gives the young man his gun. The young man makes the choice to accept death and the village is freed.
The old man stops being so mopey and accepts his bombshell of a travel companion and the two head off to places unknown.
