A Girl & Her Guard Dog Volume 9

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?
