The Lesser Wani is the Wani which competes in senshado; the Wani which commands her tank and her team through the unpredictable realities of sporting competitions and armoured combat
The Greater Wani is the Wani which looks and builds inwardly, cultivating her ladylike beauty and her soul using the external, worldy senshado content as both a catalyst and a tool for the development of her own Internal Grace.
And BOTH are very cute
