Having overcome the ferocious battle with the fearsome White Whale, Subaru
Natsuki returns to the Mathers domain.
With the subjugation force that
overcame the deadly combat, and the addition of Julius, their common history
reconciled, together they clash with the Witch Cultists under the command of
Bishop of the Deadly Sins, Petelgeuse Romanee-Conti.
To thwart the
vile schemes of "Sloth" aimed at Emilia and the others, avoid the tragedy he has
witnessed multiple times, and to defy Fate itself, Subaru's "Return by Death"
experiences open the way forward-!
"So, let me ask this of you. -Let me cling
to your back, while you carry me on it."
