Re : Life Disaster
What if someone with massive trust issues were faced with two yanderes? This is what Rex, a 17-year-old boy, faced after being betrayed by his girlfriend, murdered, and transported to another world as a hero, only to be betrayed and murdered again after helping that world.
He returns to Earth, but not the real Earth, but a parallel world called Terra, where humanity has been wiped out by a portal opening, leaving it infested with monsters and magic, despite still using technology. Rex locks himself in his room and chooses to become an introvert due to his severe trust issues, even though his powers remain the same as in the other world.
Because he always looks 17, even though he's 19, the city government forces him to attend school. He obviously chooses online school to avoid dropping out. However, a female schoolmate comes to take care of him at home every day, along with his female neighbor, neither of whom has aged as much as he does.
And this is the story of Rex and the two girls who are with him, who apparently have their own issues for being close to him and ensuring he doesn't leave the house at all costs. However, the problem is, the two yandere girls have the same powers as Rex, which leads to disaster.
