it's dipanjan.as for your answer,we see several ghouls having one kakuhou.as they eat more flesh or increase their power by cannibalism,more kakuhous emerge and the kagune looks symmetrical.if you consider ghouls being a mutant subspecies of mankind,there's a high chance of biological asymmetry.in the end it's pure luck to have dual kakuhous of same(ayato) or different type(hinami).
