UNerima usebenza njengendawo yangasemva yemo-Re karati-buciko besiphithiphithi ngalo lonke ukhuphiswano lwesiqhelo lukaRanma, njengoRyoga Hibiki owalahleka ngonaphakade ohambe isiqingatha sendlela enqumla eJapan esiya ngasemva ngaphambili kwikhaya lakhe, apho uRanma wachitha khona. ndimlindile izihlandlo ezithathu. Apho athi ekugqibeleni awele kwiNtwasahlobo yeNgwagwane, eRyoga, efuna ukuziphindezela kuRanma, wamamkela kuJusenkyo. Ngoku xa etshizwe ngamanzi abandayo uthatha uhlobo lwehagu encinane. Engakuqondi oku, u-Akane ufuna intshontsho lehagu njengamagama kunye nesilwanyana sasekhaya Pchan, kodwa uRanma uyayiqonda kwaye uyamcekisa ngokusebenzisa le meko kunye nokugcina esi sitshixo. Omnye umntu okhuphisana naye nguMousse obona kufutshane, othi abe lidada xa efumile aze awele echibini elingumlingo, okokugqibela kodwa kungaphelelanga apho, kukho umkhulu kaRanma okhohlakeleyo, uHapposai, ochitha ixesha lakhe esiba iipanty zabantwana besikolo.
