Ranma 1/2 (2-in-1 Edition), Volume 16: Miscellaneous Mayhem (Ranma Vol. 31-32 #323-344)

Ryoga + new disciple Akari + Akane + a magical umbrella = a complicated equation of dueling love. Next there’s a swimming contest between Akane and Miss Hinako that leaves one of them taking a dive. Then, a legendary dôgi - armor said to endow its wearer with ultimate power - is given to Ranma, Genma and Soun. But when the dôgi picks Akane to be its wearer, it soon comes between her and Ranma! It’s now or never for Ranma to confess his true feelings for Akane, but will he?
