Isaku never asked to be the daughter of a yakuza boss, but when her parents died in a car accident when she was 5, her gangster grandfather took her in and raised her as part of the clan. After years of being avoided by her schoolmates because of her family ties, Isaku is finally ready to make her high-school debut, live a normal life, and maybe even find love…until loyal family servant and Isaku’s dedicated guardian, 26-year-old Keiya, enters high school right alongside her and vows to protect her from all of the above! Now she’s got a chain-smoking, pistol-wielding knight-in-shining(?)-armor to deal with, and navigating high school besides? What’s a young lady to do?!
Isaku, the heiress of a yakuza clan, and Keiya, their lieutenant, are sweethearts in love! One’s a girl who just wants to be a normal teenager, and the other’s a gangster that’s masquerading as a high schooler to attend Isaku’s high school to keep her safe (and spend more time with her). Their school life is going pretty swimmingly until…Kajika, lieutenant of the Nodoguro-gumi barges into school! Will this handsome bad boy spell the end of Isaku’s quiet love life?
