Kamiyagawa, holding ichimonji, advanced alone.
The purplish-black miasma surrounding him had begun to thicken, and it required the visual skills of "Autumn's Precision" to discern his surroundings clearly.
He could see some withered trunks scattered around, all in black, twisted and deformed, utterly void of life. The scattered, brittle wood in varying heights resembled numerous desolate graves, all shrouded in an expansive sense of desolation.
"This place reeks of Yomi, shadows of death visible everywhere, lingering on... It must have been the main battlefield of the Lightless Calamity."
As he walked on, the miasma around him grew even denser.
If this abhorrent miasma was the residual aftermath of battle, and the more horrific the battle was during the Lightless Calamity, the heavier the miasma at that spot...
Then Kamiyagawa was likely treading deep within the guts of an old battlefield.
