Leon City.
After the first Undead successfully advanced to level 11 with the help of the Magic Potion, the remaining Undead found their own advancements just as inevitable.
Moreover, they were keen on "exploiting bugs"; the more inhuman their appearances became after promotion, the stronger they were.
As a result, Leon Territory saw a group of monstrously ugly creatures emerge. Whenever they walked along the streets, the people there would tremble and kneel on the ground, fearing to attract attention from these terrifying beings.
"That lizard pit almost cleaned up, not going anymore?"
"Not going! Disgusting! Lizard shit everywhere."
This game was fun because it was incredibly realistic.
But this game was also not fun, because it was too realistic.
The Undead could never forget the soft, mushy feeling they inadvertently stepped in while eagerly invading the lizardmen's territory, or the sticky substance squeezed out from between their toes.
