[Crossover] Transforms at the Drop of a Hat

Every girl has a few unhappy days each month. Xingzi discovered that her few days each month were even more miserable than everyone else's. What the heck, she randomly transforms into a League of Legends hero. Can't she just be an ordinary middle school student and go to school? She wants to study hard, improve every day, and be someone with ambition, too. Does this world that needs Aunt Flo to save it really deserve to exist? So many people play the game, so why was she the one chosen? She hasn't even played ranked. She's just a scrub who plays normal matches, bot games, and ARAM. P.S. Includes League of Legends elements, shonen manga, shojo manga, and all kinds of manga. Also includes some forum memes, though probably not many. The blurb is all fluff and might have nothing to do with the story. It might just be forum drama. Actually, this terrible author has pretty much quit playing LOL and just watches tournaments now.
