Tenshi Na Konamaiki

aka. Cheeky Angel Megumi Amatsuka, a rough and tumble nine-year-old boy, has always aspired to be the "manliest man on earth." After saving a sorcerer from a band of local thugs, Megumi is gifted a book of magic and uses it to summon a genie to fulfill a wish. However, due to an unfortunate twist of fate, the genie reveals itself to be malevolent, resulting in Megumi becoming the "womanliest woman on earth"! Fast forward six years... Megumi is now the most sought-after girl in school, yet beneath her alluring facade lies the same trash-talking, punk-stomping boy.
