Ranma 1/2 (2-in-1 Edition), Volume 14: Alter Egos (Ranma Vol. 27-28 #279-300)

Home is where the heart is, except when it’s invaded by unwanted guests. Ranma’s teacher Miss Hinako falls in love with Akane’s father and moves into the Tendo Dojo. But when Ranma tries to drive her out, Miss Hinako gives Ranma a run for his money! Later, a Ranma imposter takes up residence in the heart of Nodoka, Ranma’s mother. It doesn’t take long for the two “Ranmas” to begin fighting, and not just over their true identities.
