Feeling ill-prepared for the looming battle against Mash the Dragon King,
Seiya returns
to the underworld to acquire some new skills. But every boon
gained from this dark
realm comes at a cost. While Seiya practices a stealth
ability, Rista turns invisible! As
he hones the power of darkness, disaster
strikes! Will Seiya be able to master these
new techniques before the
drawbacks wipe out his party?!
