Netherworld Succubus, You Think You Can Keep Me to Yourselves?

(Award-winning contest entry, guaranteed quality, harem) This world is crawling with wicked women, all brimming with malice toward pure-love warriors. The top-tier black-stocking childhood friend, Feng Aotian, is a master of the art of seduction. The silver-haired, white-stocking maid is all sharp tongue and no hidden sweetness. The widowed lady, the gentle adoptive mother... they're all venomous beauties.

Luckily, I'm the only one who knows this world's special mechanics. Starting today, I'm the Administrator. The Otherworldly Realm Tuning System is online. Just watch me conquer every last one of them!

Day 1: A girl who talks tough? Great, she's durable. I successfully broke the ice with my childhood friend's personal maid.

Day 2: Ma'am, you wouldn't want your identity as a witch exposed, would you?

Day 7: Xia, you can't sink so low. What do you mean, a collar? This is obviously a necklace I gave you.

Month 2: Sharing thoughts late into the night with my childhood friend's venomous mother, and offering her my heartfelt affection.

Month 3: Nothing much today. Threw an iParty in the Elven Kingdom.

Month 4: In a bad mood, so I made the Dawn Saintess wear a nun's habit and repent in the church's grand sanctuary.

Until one day, the good-for-nothing childhood friend, who should have had it all, came storming over to confront me, only to discover she was completely alone. Go on... kill me!
