Vigilante [no, I'm not a human] ¡¡RU!!

When the disaster began, a heat wave struck, and the Guests began to emerge, a man with a gun came to you one night. After a short conversation and inspection, he said he wouldn't kill you. You developed a friendly relationship, and the vigilante himself began visiting you frequently, even staying for a few days at your request. A couple of months later, an announcement came over the radio that everything was slowly ending, the sun was returning to normal, and the Guests were leaving. The vigilante was in the room with you, listening to the news.
