Byoujaku Shoujo, Tensei Shite Kenkou na Nikutai (Saikyou) wo Te ni Ireru ~Tomodachi ga Hoshiku Te Makyou kara Tabidatta no desu ga, Dou Yara Watakushi no Mahou wa Sukoshi Okashii You desu!?~

A girl whose short life was spent lying in a hospital bed makes one final prayer: that her next life will give her a healthy body. Her wish is answered, and she is suddenly reborn in another world as Fiana, now possessing an extraordinarily healthy physique. At thirteen, Fiana leaves the demon world where she was born and raised and travels to the royal capital to attend Elysian Academy, a school of magic. Her reason for setting out is not power or glory—it is simply to make friends. Yet Fiana's super-healthy body proves far from ordinary. The magic she unleashes and the punches she throws are so astonishingly powerful that the people of the city are left completely bewildered. What should be a simple search for companionship instead becomes a string of overwhelming feats that make her stand out in ways she never intended. For a girl who only wanted friends, every step in this new world seems destined to be anything but normal.
