It's called TerrorRune and well....it's based on the horrortale in undertale.
Up above a virus appeared making everyone have cannibalistic tendacies somewhat like zombies and due to this there was placed quarantined that the virus couldn't exist at, which was where monsters lived. Because of this many moved to not gain the virus, unfortunately many infected moved into a certain town where Kris lived, this caused many safezones to be compromised, killing many monsters. Luckily Kris and Susie met up. Susie somehow overcame the virus and now only needs to drink blood once in a while and her appearance changed, Kris meanwhile also gained the Virus and ended up mutating the virus making their eyes look corrupted and this caused many survivors to attack them thinking they were mindless beasts. Eventually they both fell into the deltarune world and Ralsei found them. He explains that the virus came into their home and deformed them into monstrosities and that the two of them are the heroes to help them. I'm their way to find a cure that meet Lancer who is appart of a group of scavangers that poor dead bodies and eat them, however Lancer ranaway when he found out what they were doing and now journeys on his own.
Lancer, who found what they ( ralsei, Kris and susie)were trying to do joined them on their quest. Unfortunately they had to quit as their efforts were stopped by an anonymous force, and that they now live in Ralsei's castle. Waiting.
So that's the basis so far. If prob write the story one day but for now......here are everyone's personalities and who's alive and all that
Kris-alive- somewhat shy but will fight of they have to, they are one of the only surviving humans.
Susie-alive- protective and hardheaded, has mellowed down from easily angered due to meeting Lancer.
Ralsei-alive- his personality is the same but he is more ruthless when it comes to protecting his home, he isn't affected by the virus badly and was only given the mutated form and preference to raw foods.
Lancer-alive- soft spoken and wary, he takes everything seriously and due to unknowing of his dad's and family's whereabouts he has become possessive and clingy to the trio.
Kings- unkown- belived to have perished
Roulxs kaard-???- possibly alive somewhere
Toriel and asgore-dead- Kris had to kill her and asgore after the virus infecting them turning them to try and devaour Kris.
Sans and papyrus- unkown- believed to be in one of the safe zones
Undyne- Dead- eaten alive by alphys and the infected students.
Asriel- ????- possibly in one of the safezones.
