[Pseudo-Crossover] Evolve! Golden Flash!

She is the ninth Chosen Child, entrusted with the vital mission of saving the world. But wait, before we get to that, can someone explain what this cup, supposedly called the Holy Grail, is all about? "Hey, woman, are you the one who summoned me?" ...Why does this golden-haired Pika look so familiar... What the hell, I must have transmigrated the wrong way! Reader's Guide: ★ One-on-one romance. The pairing is with Takaishi Takeru, definitely not Gilgamesh, so please don't ship the wrong couple. The male lead is definitely Gilgamesh. ★ Original heroine, transmigrated Mary Sue, severe chuunibyou, comes with a golden finger, guaranteed happy ending. The goal is to mess with Golden Gil. Gil fans, proceed with caution. ★ All original characters and Digimon remain unchanged. The Holy Grail War characters are just there to make cameo appearances. ★ If you feel uncomfortable while reading, silently call the author an idiot, then smile and click the X. Thanks to my friends for suggesting the title! The author's imagination has gotten so out of hand that I can't tie it all together anymore!
