Gozuki

First mentioned in Day 161.

A bull-headed demon that is equipped with living body armor that is shaped like large armor.

Appears similar to Mezuki.

While Gozuki are superior in terms of the destructive power of their blows, Mezuki surpass them in terms of speed and like to play with their enemies.

The heavy offensive unleashed by the coordination of these two demons deals a lot of damage and has defeated many adventurers, including those who can make it to the last level of the dungeon.

They are both a strong species to begin with, and they are further strengthened by the effects of the dungeon. I hear that currently they're only taken out about once a month because of their considerable strength.
