Joining the recently added Heroes in Heroes, Light and Shadow is Eremiya: Bishop of Woe, who can now be challenged in Grand Hero Battles until the daily rollover on 3rd August 2020 (UTC).
For those not familiar, Eremiya is the leader of a group of assassins from New Mystery of the Emblem, serving under Gharnef. She’s probably the last notable villain to be added from the Archanea arc, besides Medeus, the Shadow Dragon.
If you want to know her better, check out her Meet the Heroes page (there are spoilers, but that’s nothing new). Oddly, her images are labelled as “Jeremiah: Hollow Bishop” (Eremiah was her name in the fan translation for a spell). It’s probably just a placeholder though.
Anyway, please keep reading if you want to know her abilities and whatnot.
