U-Akane, oneminyaka yobudala kaRanma, uqokelwe odadewabo ukuthi asebenzele abashadikazi besebenzisa ukucabanga okunengqondo ukuthi ngoba uRanma ungumfana nje oyisigamu saleso sikhathi futhi u-Akane akabathandi abafana, baphelele ndawonye. Bobabili u-Akane noRanma bayakwenqabela ukuganana ekuqaleni, njengoba bengazange babonwe esiphethweni, kepha-ke ngokuvamile bangaphathwa njengabathembisayo futhi bagcine ukonga noma basizane kweminye imicimbi.

INerima isebenza njengomlando ongemuva we-mo-Re karate-arts mayhem nakho konke ukuqala kwemincintiswano kaRanma, njengoRyoga Hibiki olahlekelwe ingunaphakade owahamba ibanga lonke enqamula eJapane eya ngemuva ngemuva kwendlu yakhe, lapho uRanma achithe khona kathathu emlindile. Lapho ekugcineni ewela khona eSpirit of Drown Piglet, uRyoga, efuna ukuziphindiselela kuRanma, wamamukela kuJusenkyo. Manje lapho efafazwa ngamanzi abandayo uthatha uhlobo lwengulube encane. Engakuqondi lokhu, u-Akane udinga ukuthi le ngulube ibe ngamagama nesilwane asifuyile uPchan, kepha uRanma uyamqonda futhi uyamzonda ngokusebenzisa lesi simo nokugcina lo khiye.
