"Didina the Fortunate" lived a life that her fellow succubi were incredibly envious of as she was the ruler of the Bloody Arena. Not only did she have authority, the addictive feeling of being at the top was something those in authority would never be able to give up.
Didina didn't need to suck up to anyone in order to become a ruler. Many succubi viewed her as their idol. Didina's harem also contained many other succubi… in the past.
Have the perceptive readers noticed something off? At any rate, succubi weren't limited to only targeting males.
