Crossover: Science Forbidden

My name is Xia Mu Yin, and I'm an ordinary high school student. I attend Academy City. When I was ten, my two best bros and I formed a love triangle. Just as I was starting to think something was wrong with my youth story, a dark-skinned girl told me I was one of the heirs to the Vongola family. But before I could figure out what the hell was going on, a Rainbow Squad charged at me, yelling and fighting me. I barely survived, and before I could enjoy even two days of peace, I got dragged into a dirty deal between Academy City and Millefiore. Then I was told that if I wanted to save my bros and keep acting out this youthful love triangle, I'd have to collect fourteen wedding rings and seven ancient pacifiers. Only then could I pass through the Gate of Truth, reach the Divine Dragon, and make a wish. Sigh, my life is so scientific. The female lead isn't weak. She's also very cocky, so be warned. ←W←
