Goth-rock yokai trio superstars "Geryon" are one album and tour away from dwindling from the public eye. Using the funds from their devious employer, "Franz Cifer", they retire in secrecy away in the mountains. Everything is perfect for the three - that is, until one of Franz' henchmen, a small monster named Pudge comes and drags them from their luxurious lifestyles and forces them to tour the most haunted (and dangerous!) venues in the Japanese underworld! It's the roadtrip of an (after)life as the sassy and foxy kitsune front-man Kevin, catankerous and overbearing raven-tengu bassist Kurasu, and slovenly and super-strong kappa drummer Kipp go on tour to repay Franz and make good on their debt.
