The Succubus Hero Will Never Submit to the Demon King!

The following is taken from the diary of [Amamiya Liuli: Super Strong and Amazing, Not a Jerk, Definitely Won't Lose to the Demon King, Overflowing with Dominant Energy, The One on Top]:

Day One. Good news: I transmigrated, and my magic aptitude is off the charts.

Bad news: I can't use a single offensive spell.

Day Two. Good news: I'm the Hero.

Bad news: I'm also one of the Four Demon Generals, and the Demon King is my boss. That embarrassing holy sword is completely useless. I can't beat her.

Day Three. Good news: Quit, slack off, run away! (By the way, the Demon King is a white-haired little girl. She's super cute and even acts all clingy with me.)

Bad news: The Demon King got mad out of embarrassment and threw me in a death cell.

Day X. Good news: After a long struggle (so I'm told), I finally escaped the demon realm. No more living in fear beside the Demon King. A romantic life of adventure is about to begin!

Bad news: Why does this white-haired slave girl I bought look so familiar?

Day N. Good news: The Demon King admitted defeat to me today, all on her own (a huge victory!)

"Mew! Wait, don't play with my tail! I'm writing in my diary!"

"Have you forgotten our agreed-upon conditions, Sister Liuli~?"

"Ugh... I'll be on the bottom tonight... Honestly, which one of us is the succubus?"
