A project born from boredom.
The setting is modern-day Japan.
Yokai hide their true identities from humans, living integrated into human society unnoticed.
One day, at a grand banquet where the yokai gathered, Tamamo-no-Mae teased Shuten-doji relentlessly, leading to a massive brawl.
Infuriated, Shuten-doji parted ways with the other yokai and began rampaging through human society with the Oeyama faction as a way to vent her anger.
At this rate, the peaceful life of humans and yokai could collapse.
To settle the situation, the yokai nominated "Nurarihyon," who is deeply trusted by all, as Supreme Commander and formed the "Yokai Alliance."
Thus, triggered by a brawl at a single banquet, the "Yokai War" that shakes modern Japan begins.
