Number 17 of the project. Princess Molestia is, like most of the other Wu characters, comedic. Her ability is based on an ability from original LTK - Sun Shangxiang’s ‘marriage’. Personally, I don;t like that ability, because Sun Shangxiang is one of the two female characters depicted in the novel who are not serving only as eye candies. The other is Huang Yueying, a female inventor and mechanic who have scars on her face due to experimental accidents. Sun Shangxiang is the only female warrior in the whole novel, and yet in LTK’s design one of her ability is ‘marriage’?  
But you can’t argue that in actual gameplay, saying the phrase ‘I marry you’ is fun. Similar jokes were in Zhen Ji’s ‘I had a period’ and Da Qiao’s ‘please rest’. LTK can have some dirty jokes, which, ironically, Diao Chan, depicted in the novel as ‘the beauty’, became a high skill floor long range control mage in LTK and is arguably one of the most skill expressive character.  
Back to the main topic. Princess Molestia’s ability is: you duel the target. Whoever wins the duel, would be able to decide if they use ‘marriage’ or not. I would even admit this concept came from Billy Herrington, who was unironically really famous in China, and you would understand the joke if you have indeed watched ‘King of the locker room’. May he rest in peace.
