I'm Standing on a Million Lives Vol. 9 (manga)

EPIFANIO'S INTRIGUE

The Dragon Priest's ritual has begun, slowly sapping the denizens of Ihar-Nemore of their life force. The land is doomed unless Yotsuya can finally put an end to Epifanio's foul magic. As everyone unites against this common enemy, it seems like the day may yet be won, but things go from bad to worse when an army of giant mantises begins to march through town! Could this, too, be part of the Dragon Priest's dastardly plan?
