The origins of

Obon

can be traced to the Ghost Festival of China. Which, in turn, is a festival with roots in the Taoist

Zhongyuan

and Buddhist

Ullambana.

Given how the very practice of jujutsu itself also holds heavy Buddhist influences, it 's unsurprising that the sorcery clans would naturally regard Obon with all the gravity and significance that such a festival was due.

'So Obon is really important? '

'It is, yes, ' Shiki nods. Tsumiki-san makes a soft sound of understanding, while beside her Megumi-san ' doesn 't visibly react, but it 's clear that he 's also listening intently to her words. 'Obon is specifically meant to honor ancestral spirits and pay respect to the deceased. '
