King of the Girls
The wife of a zaibatsu of the circuitry industry dies giving birth, forcing him to swear on her dying breath to give his company to their
firstborn.To his dismay, his firstborn, Akira, is a girl. A man of his word, he puts her daughter through the best engineering boarding school from a young age, where she graduates top of the class. The problem is, it was an all boys academy.
The story begins with her returning to her mansion from a wild graduation party, her passed-out best friend, Ichigo, carried by her arm. He is a shy and soft-spoken student who graduated third in class, who Akira took under her wing. Upon meeting his rarely-seen daughter, he is shocked to discover that she is in fact very masculine, very rowdy, and very much a boy, even down to her flat chest (although her other proportions are very feminine). Instead of being ashamed, her father is very proud, congratulating her on her success and independence, and they share shots while he gives her and her friend father-to-son advice about how to make it big at college.
She and her friend arrive at college, and she quickly becomes the talk of the campus, participating in many clubs, getting on the student council, and overall being the shining model of a student. Unfortunately, an unexpected kink hits her life: females. She doesn't understand other women, and more importantly, she is very attracted to them. All of them. From moe to girl-next-door to loli to tsundere, she is enamored by their personalities, and more importantly, their bodies. Taking her father's advice, she decides then and there to put her hand into every pie, and make every girl who she meets her lover.
She fails miserably. At the end of her wits, she partners with Ichigo and his new friends, and the series expounds on their misadventures of acquiring girlfriends, all of them using their objective, calculated skills as engineers to crack the mystery that is a girl.
