Meet the Resolute Vanguard: Heroes of Earth and Beyond

Hello! connects to the others. In this story, a superhero team with various powers works together to save the world, both on Earth and in space, and defend against enemies. By the end, only one of them survives, while the others perish, sacrificing themselves to save the world. However, people mistakenly believe they were villains, though this is far from the truth. In the latter part of the story, the protagonist’s girlfriend is killed by the enemies. Initially, this tragedy leaves him deeply depressed, but he eventually returns to fight against the threats once more. Her role should be impactful, but ultimately she dies. The story should blend drama, superhero elements, and science fiction, and should be written in English. Choose strong, fitting names for the characters that sound English, and start the story like an excellent writer would.
