Horror game, but harem plan

Walking corpses, Ranying Academy, drowned corpses at the bottom of the lake, red wedding dresses, alien insects, faceless men... Facing these monsters, the only way to survive is to fight.
Yang Ming turned around and looked behind him, and saw girls such as Ijichi Hongka, Goto Ichiri, Hayasaka Ai, Shinomiya Kaguya, etc.
It would be nice if it was a daily youth game instead of a survival game with monsters and demons running rampant.
At this point, there is no turning back.
The sledgehammers will smash their heads, and the shotguns will blow up everything that stands in their way.
Come on, how can we let a beautiful girl die in a place like this? I want to create a happy world where there is no loss!
