Honkai: Star Rail: From the Start, I Was the Aeon of Elation's Daughter

One day, Aha, the Aeon of Elation who roamed the Star Rail universe, suddenly announced that they had a daughter. The entire cosmos was shaken. People thought that now the Aeon of Elation had a daughter to worry about, they might settle down a little. But who could have guessed... The daughter was even more outrageous than her father. She plucked abilities from the Aeon of Elation and used them to become an Emanator of Elation. After teaming up with her childhood friend, the troublemaker Sparkle, to blow up the planet her father lived on, Yan Ai began wreaking havoc with Sparkle across planets throughout the universe. She helped the Hunt chase the Abundance, made a wish for Destruction, discussed the Dao with Elation, and slept alongside Remembrance. She used the power of Propagation to feed Voracity's endless appetite, then planted Nihility right where Preservation was building a wall. She made tiny Black Towers and filled the space station with them. She stole Cocolia's mech, leaving Cocolia nowhere to turn evil. She smashed Fu Xuan's divination board and brought about a 996 work schedule on the Xianzhou. She stole Aventurine's cornerstone, gnawed on Sunday's chicken wings, helped the IPC seize the Family, and helped the Family drive out the IPC. In short, she did everything the Aeon of Elation did, and everything the Aeon of Elation didn't do. Her motto: gods and mortals are equal, and everyone gets a little fun. Welcome to the Elation!
