Perfectly Ordinary, Tennis Club Manager!

[Announcement: I'm busy in real life, so I'm unpublishing the story and putting it on hiatus. I don't know when I'll be back, but I might add a few extra stories about reuniting with Ace in the future! Thank you so much for staying with me and my girl Xia Lan all this time, and thank you for understanding. I hope we can meet again someday. I'm truly sorry!! I still love you all. I hope every day ahead is happy, healthy, and joyful for all you sweethearts!] On the eve of the college entrance exams, fate played a cruel trick on me and forced me to transmigrate to another world to complete a series of bizarre tasks. [Task One: Rescue the Fire Fist, who is about to be executed] Me, looking stunned: "Who's Fire Fist? He sounds really impressive, but I'm just an ordinary high school girl who can't even hurt a fly!" [Task Two: Eliminate the spiders] Me, thinking hard: "I can probably manage that one... Wait, I don't think 'spiders' means what I thought it meant. What can an utterly average person like me use to take out an A-rank wanted criminal? My tennis racket?!" [Task Three: Get 50 million from the eldest son of the Zoldyck family] Me, gradually losing my sparkle: "I have no choice but to put on a show. I wonder if their kids would like to learn tennis..." [Task N: Stop an alien life-form from destroying Earth] Me: "??? System, can we please be a little more realistic!" After going through eighty-one hardships, I finally completed all the tasks and returned to my own world. The first thing I did after getting home was visit the tennis clubs at various schools, take each tennis boy's hand in turn, and sincerely thank them. "Atobe, thanks for your [World of Ice]. Otherwise, I would have almost melted in Akainu's magma!" "Kuwahara, our Kansai Speed Star! Thanks to your speed, I survived the spiders!" "Mura-nii, you're a god forever! Your [Five Senses Deprivation] was so useful, sob!" The boys, completely baffled: … Hm? Reader's Guide: 1) Also known as "Scientific Tennis Saves the World." A hilarious, lighthearted story. 2) There's a romance, but the plot is mostly silly comedy. The pairing is Fire Fist, one-on-one. 3) The quick transmigration worlds feature Devil Fruits, Nen, the rich folks' PR department, curses, a little stray dog, a bald hero, and tennis killers. 4) The heroine is strong, and her power is scientific tennis! Pre-release: "Well Prepared [Online Game]": Bai Yan takes on a little apprentice in a game. The apprentice is obedient and well-behaved, but never uses voice chat, so they communicate during dungeons by typing. During an important boss fight, Bai Yan asks the apprentice to turn on the microphone. After hesitating for a moment, the apprentice obediently does so. "Master." The apprentice's voice is quiet and slightly cool. Bai Yan is stunned. "...Holy crap! Your voice sounds just like my boss's!" "Does it?" "Yeah, it's uncanny. Come on, call me Master a few more times and make your Master happy!" "...Master." "Good apprentice!" Some time later, during a guild battle. Bai Yan and her apprentice join forces and wreak havoc, winning first place for their guild. Overjoyed, the guild leader suggests treating all the guild members to a real-life gathering. The day everyone meets in person, Bai Yan arrives at the agreed-upon location, excitedly looking everywhere for her mysterious apprentice. But her gaze lands on someone who shouldn't be here. A handsome, tall man in a dark navy suit walks toward her. His shiny black dress shoes stop in front of her. "Bai Yan." After saying her name, he smiles lightly and asks, "Or should I say, Master?" The word "Master" sounds flirtatious, and Bai Yan freezes completely. Wait, why is her direct supervisor here!!! Theme: Perseverance brings victory.
