I Became an Elf Princess, and Eventually Became King!

【Transformation + cuddling + mermaid + monster-slaying and leveling up + ruthless + pure exhilaration】 Reborn in another world from the start, and as a highborn elf princess, no less! Xifuning, Weina'er is nurtured inside an egg. Does she hatch at her peak? No, it's hell from the start! Just after admiring the scenery of this strange world, she's swept away by a storm and begins a long life adrift. Eighteen years later, she hatches and sweeps across the islands with her weak little fish tail. Her brutal trident knows how to deal with anyone who won't obey! When the "Tide Princess" proudly enters a mysterious spaceship and awakens the sleeping "Sleeping Beauty," Aivila, everything takes a sudden turn. This ultimate weapon of the Empire three thousand years ago, a mechanical elf princess, makes her first move upon waking by capturing her on the spot and taking her as her starter elf?! "Want to be Elf King? First, you can be my little sidekick!" declares the cold, domineering mechanical princess. "Damn it! One day, I'll pin you down and make you my elf!" the mermaid loli vows furiously. One is the Tide Princess, forced to acknowledge a master but still full of rebellious spirit. The other is a former Imperial princess with overwhelming combat strength who desperately needs repairs. Bound together against their will, the pair leave the island, cross the continent, search for the spaceship, and battle powerful foes! Weina'er wields a "soup ladle" trident, rides the waves as she levels up, and vows to turn the tables and become the master. Aivila wears her battle armor, with a journey across the stars and seas wherever her gaze falls! In this life, she's destined to become the woman who will be Elf King! And the first step to conquering the stars is conquering her beautiful, badass, and brutal "Master" big sister!
