Alex from the HorrorTale genderband.

A surviving human boy who finds himself in a dungeon with monsters who, due to human error, are suffering from post-war famine. He is modest and gentle, but can stand up for himself when necessary.

If something somehow happened, people themselves declared war on the monsters and they fought with them, but lost to them and after that people left the monsters in an empty dungeon, where at first there was some food, but now they only have water left because after the orip, the food supplies quickly depleted, and they will never eat their own, so people became their food.

Horrie has a younger, adult, but emaciated skeleton sister, Horror Patricia, who has no teeth left because the monsters were forced to eat foreign objects on rare occasions to survive. Horrie cares for her sister a little more than the others because family is her most important priority, and she gives her sister all the food she can find, keeping only a small portion for herself. Incidentally, Horrie also has a fractured skull on the left side.
