Ageze iwe, ati:<<Nje kugukeza ngo unsindire iki cyago cy’inzara!>> R waserera aramwemerera, aramuhaka. Amushyira mu bahinzi be barahingana. Bukeye Rwaserera ajya kureba uko abahinzi be bahinga .Asanga Rubanguka yihagarariye. Amubonye ,aramutonganya,aranamutuka ,ati:<< Dore ngo iyo nyana y’imbwa y’umuganza w’umudeshyi ngo irandeheshereza abahinzi; nkabona iwanyu mwararimbuwe n’inzara ni ubwo bunebwe bwanyu!>>

Agezeyo abitekerereza abaturanyi be, ababwira uko Rwaserera ari umugome waagutswe n’umurengwe bikabije. Amaze kugenda Rwaserera biramubabaza ati:<<Nta w’undi muganza nzongera guhingisha cyangwa ngo muhahire.>> Kuva ubwo,uje kwa Rwaserera guhakwa, akamubaza aho aturuka.Yamubwira ko aturuka i Buganza, akamwirukana. Abanyabuganza babura aho bahahira. Haciyeho iminsi, Rubanguka abagisha inama yo gutera Rwaserera ngo bamunyage ubwo bukungu akangisha. Baranga, bati:<<Nta bwo twakwiteza umuntu ejo bitazatugwa nabi mu batware cyangwa ibwami; abandi barembejwe n’inzara baremera bati: << Tuzamutera ahubwo bazatwice aho kwicwa n’inzara!>>
Nuko ngo bugorobe,barikora baboneza iy’i Rusororo ijoro ryose: umuseke wa mbere utambitse bavuza induru ndende, bati:<<Umwami yatanze Rwaserera !>> Rubanda bakangukira hejuru, abanyanzara bose:babyumvise batanguranwa kwa Rwaserera; mbese igihugu cyose kirashika n’isahinda gitera Rwaserera! Baramusakiza basahura ibyo yari afite byose. Urugo baruha inkongi,ahari iwe haratikira hazize uwo mucanshuro Rubanguka rwa Mhama w’i Kiramuruzi.
